Humidity Control With Nitrogen Gas

Optics Clean Room
Controlling and maintaining humidity levels in an enclosed environment or vessel is a crucial component of controlled atmospheres such as clean rooms, archives, and dry boxes.  We've written earlier posts relating to this topic including Nitrogen Gas Uses for Clean Rooms and Dry Boxes Use Nitrogen Gas to Prevent Moisture.

Nitrogen gas is used to control humidity in enclosed environments because it is a safe, dry, inert gas that is found naturally in the air we breathe.  Using a simple PSA Generator or Membrane Generator technology to separate and isolate the N2 molecules, a Nitrogen Generator collects the resulting high purity N2 gas in an attached storage tank ready for use.

By controlling the levels of Nitrogen Gas introduced into an enclosed vessel or room, oxygen levels will be reduced and the N2 gas can absorb moisture, thereby helping to maintain a dry and less humid atmosphere.

A Nitrogen Generator is capable of producing varying levels of N2 output and purities, depending on the application.  South-Tek Systems uses a Nitrogen Flow Meter to monitor the flow rate requirements of a particular application, whether it's a clean room, dry box, or valuable archive storage area, and then provides the optimal Nitrogen Generating System for that application.

South-Tek Systems designs and manufactures a range of Nitrogen Generating Systems including:

Portable Nitrogen Generators
Compact Nitrogen Generators
Tank Mounted N2 Systems
and more!

Controlled Atmosphere Storage Using Nitrogen

Controlled Atmosphere Storage Apples
Nitrogen gas is widely used in food packaging processes and in food storage in order to preserve freshness, taste, texture, and flavor for longer periods of time.  We've written about the benefits of Nitrogen for the food and wine industry - particularly with food and beverage packaging - in earlier posts including Keeping Food Fresh with a Nitrogen Generator and Modified Atmosphere Packaging (MAP).

Controlled Atmosphere Storage of Fruit and Produce

Nitrogen gas can also be used for creating and maintaining a Controlled Atmosphere (CA) for food storage, specifically for fruits such as apples and pears that "breathe" by taking in oxygen and giving off carbon dioxide in the ripening process.  By creating a storage atmosphere that carefully controls temperature, oxygen, carbon dioxide and humidity levels, apples, pears, and other produce can remain fresh and crisp much longer because the ripening process will be significantly slowed.

Why Use a Nitrogen Generator for Controlled Atmosphere Storage?

Nitrogen is often used in the Controlled Atmosphere Storage of fruits.  Using a Nitrogen Generator to supply the appropriate levels of N2 gas, the CA Storage Room experiences a reduced amount of oxygen and humidity to hold off the ripening process and preserve and maintain the freshness of the fruit.

A Nitrogen Generator is an ideal way to help manage a Controlled Atmosphere Storage Room.  The PSA Generator or Membrane Generator technology produces high purity N2 gas directly from the air without use of chemicals or other harmful toxins.  An N2 Generator ensures you will never run out of gas and eliminates the need for costly gas deliveries and handling & storage of high pressure gas cylinders.

Contact South-Tek Systems

South-Tek Systems is a engineer and manufacturer of Nitrogen Generators used in a wide variety of industries, including Controlled Atmosphere Food Storage.  Contact South-Tek Systems today to learn how your company can benefit from using a Nitrogen Generator for your CA Storage Room: 888-526-6284.

Nitrogen for Corrosion - A Safe and Reliable Solution

Nitrogen presents a safe and reliable solution for corrosion prevention.  Corrosion can be a major issue for any industry or operating system that combines metal, moisture, and exposure to oxygen or metal exposed to acids, bases, salts, oils, solid and liquid chemicals, and some gaseous materials.  Corrosion can eat right through metal, starting with pinhole leaks and leading to inefficient or inadequate operation of the system - and ultimately system failure.

Industries at risk for corrosion include facilities such as power generating plants that utilize cooling towers or other water related cooling mechanisms as well as HVAC systems, Fire Protection Systems (FPS), chemical processing, water treatment, and more.

How Can Nitrogen Prevent Corrosion?

Nitrogen gas is particularly effective at preventing and inhibiting corrosion in enclosed metal vessels such as piping systems or tubing that may come into contact with moisture and also be exposed to oxygen.  Prime examples of this would be the boiler tubes and condensers in power plant cooling towers and the dry or pre-action sprinkler system in fire protection systems.

Power Plant Cooling Towers

Submerged metal parts of cooling towers, such as boiler tubes and condensers, are at risk of exposure to oxygen during shut downs and layups.  When exposed to O2, corrosion can spread rampantly if not actively prevented.  Even with all the water drained, residual moisture is inevitable and corrosion can take hold from there.

A solution here would be to purge all wetted parts with Nitrogen gas to eliminate the presence of oxygen and prevent the risk of developing corrosion.  The most efficient way to apply Nitrogen in this situation is to use a Nitrogen Generator.  This allows for a continuous N2 purge without risk of running out of gas.

Fire Protection Systems

Dry or preaction fire protection systems are generally commercial sprinkler systems that run a supervisory gas through the pipes rather than water.  The water is constrained by a valve held in place by the pressure of the gas.  These systems require testing with water and inevitably residual moisture will be left behind within the pipes.  This situation presents a great risk for microbiologically influenced corrosion (MIC), a form of corrosion that starts with water-forming bacteria that can spread quickly and destructively throughout the system.

Using Nitrogen as the supervisory gas in dry or preaction FPS eliminates the threat of MIC corrosion by eliminating the presence of oxygen - one of the elements necessary for oxidation (corrosion).  As with power plants, a Nitrogen Generator is the most efficient, reliable, and effective method for applying N2 gas in a steady, continuous supply as needed.  A Nitrogen Generator supplies high purity N2 gas on-site and on-demand with easy operation and minimal upkeep.

Corrosion Prevention


Pinhole Leaks in Dry FPS System

Corrosion poses a major threat to any metal object that is exposed to both moisture and oxygen.  This goes for metal piping, a metal protective covering or encasement, a metal roof - anything made from metal that is exposed to the elements.  The contact of both moisture and oxygen with the unprotected metal starts the corrosion process, also known as oxidation, that can create pinhole leaks in the metal and, ultimately, cause deterioration and breakdown of the object.

Corrosion prevention is essential to the performance of the metal substance, assuming it serves a useful purpose such as conveyor and/or protector.  Without corrosion prevention, an operator is at risk of timely and expensive repairs to the object - whether it be a pipe, an encasement, or a roof - and is potentially looking at complete shut-down of operations while the repairs (or full system replacement) are made.

Solution for Corrosion Prevention

A reliable solution to corrosion prevention comes in the form of Nitrogen gas.  Nitrogen is found naturally in the air all around us and, when isolated, serves as a dry, inert gas that can eliminate the presence of oxygen in an enclosed vessel such as a piping system designed to convey water.

A Nitrogen Generator can supply literally endless amounts of N2 gas at the appropriate output level needed for a particular application.  It uses a simple PSA Generator or Membrane Technology to isolate Nitrogen from the air around us.  The high purity N2 gas is stored in an attached storage tank and hooked up to the gas line for use.  A Nitrogen Generator eliminates any worry of running out of N2 gas or of handling high pressure gas cylinders.


How Can Nitrogen Help With Corrosion Prevention?

Here are a couple example applications of how Nitrogen gas can aid in corrosion prevention:

Dry or Pre-Action Fire Prevention System (FPS) - a dry or pre-action FPS is designed with a valve that keeps water out of the piping.  The valve is held in place by the pressure of supervisory compressed air pumped through the system. When the system's temperature gauge registers enough heat to release the compressed air, the decreased pressure allows the valve to release and send water through the pipes to the sprinkler heads.  This type of system is susceptible to corrosion because of the moisture that stays behind after system testing or operation.  This moisture combined with the compressed air within the metal piping will is enough to start the corrosion process.

Using Nitrogen as the supervisory gas in a dry or pre-action FPS instead of oxygen is extremely effective in corrosion prevention.  The MICBlast Corrosion Inhibiting System with an internal Nitrogen Generator is specifically designed for FPS corrosion prevention and can help ensure that an FPS can void pinhole leaks caused by microbiologically influenced corrosion (MIC).

Power Plants - Power plants utilize boiler tubes and condensers that are often made of metal and exposed to moisture.  During a layup or plant shut down, these wetted parts can be drained but residual moisture inevitably remains and, with the exposure of oxygen, the process of corrosion immediately begins. 

A Nitrogen Generator can produce Nitrogen for power plants at a fraction of the cost of using high pressure cylinders.  Plus, N2 gas can be generated on-site and on demand without risk of running out.  This is extremely beneficial for the power plant industry who can face high risks and costly repairs due to corrosion.

Nitrogen for the Beverage Industry

Nitrogen is a useful and important gas for the beverage industry - from breweries to winemakers to restaurants and bars.  N2 gas can be applied in a number of ways to help preserve the product, streamline the production process, eliminate the threat of oxidation which could alter the taste and freshness of the beverage, or simply help deliver the best possible drink to a consumer.

How is Nitrogen Used in the Beverage Industry?

Nitrogen gas is a safe, clean, dry, inert gas that is typically used for purging but can also be used for preservation or can be blended with CO2 for the optimal level of carbonation.

We've discussed the value of Nitrogen in the Winemaking process in previous posts:
Whether it's sparging, blanketing, or flushing, Nitrogen can be used in wine transfer, bottling, and topping.  It's also used with the end product in terms of preserving an open bottle of wine and preventing oxidation.  South-Tek Systems manufactures the WineLast™ Wine Bottle Nitrogen Purging System ideal for restaurants and bars serving wine by the glass who need to maintain freshness in the open bottles.

Breweries use Nitrogen to control oxidation and maintain freshness throughout the brewing process and in the bottling and canning stages.

Restaurants, pubs, and bars use Nitrogen mixed with CO2 to produce the optimal beer gas blend for draft beer recommended by brewers.  This mixed beer gas pushes the beverage from the keg to the taps to produce a ideally carbonated draft pour.  This process eliminates over-foaming, allowing estbalishment owners to reap more profits from their draft beer service in addition to serving high quality beverages from the first glass from the keg to the last.

South-Tek Systems engineers and manufactures the BeerBlast™ Mixed Beer Gas Dispense System for restaurants, bars, and event centers to produce this ideal beer gas blend and optimize their draft beer service.

N2 Packaging Using a Nitrogen Generator

There are a vast number of industries who require careful and precise packaging for their products.  The packaging system they use affects the integrity and overall quality of the product.  Packaging may prevent breakage or crushing of the product or it may ensure a sterile environment to maintain optimum safety.

Some industries that require careful packaging of their products include:


  • Medical and Dental Supplies
  • Surgical Supplies
  • Chemicals
  • Food and Beverage
  • Pharmaceuticals
  • Personal Care
  • Beauty Aids
  • Oils and Lubricants
  • Household Cleaning
  • Electronics

Nitrogen Purge for Packaging

A Nitrogen (N2) Purge for packaging is a safe, reliable, and cost efficient solution to protecting packaged goods.  Nitrogen gas can protect against damage, breakage, or crushing as well as add strength to the container.  Nitrogen can also increase the shelf life of packaged goods, maintain a sterile environment, and preserve the flavor and color of your product. (See: Nitrogen Use with Medical Device Packaging and Save Money, Preserve Quality Using Nitrogen for Food Packaging.)

How Does Nitrogen Packaging Protect Your Product?

Nitrogen is a clean, dry, inert gas that can be applied to an environment to take the place of oxygen.  Oxygen can be a factor in corrosion, combustion, decay, bacteria growth and other processes that will undermine the quality and integrity of a product.  By replacing oxygen using a Nitrogen purge within a sealed package, the packaged product will last longer, stay clean and protected, and will have preserved taste, color, flavor, and texture.

Using a Nitrogen Generator for N2 Packaging

A Nitrogen Generator can be used to administer a Nitrogen purge for packaging in a more efficient and cost-saving manner compared to using high pressure N2 cylinders.  South-Tek Systems engineers and manufactures Nitrogen Generators for use with any kind of packaging needs - food, medical, electronic, and more.

Modified Atmosphere Packaging (MAP)

Modified Air Packaging - or MAP - is a process used primarily in the food packaging industry to keep food fresh, preserve taste and texture, and ensure safe delivery and storage.

Why Do We Need Modified Air Packaging?

The biggest threat to food packaging and preservation is oxygen.  Oxygen reacts with the food causing oxidation and affecting the quality, taste, texture, and safety of the product. If oxygen can be safely reduced or eliminated within the packaging during transportation and storage (without adding any other harmful elements to achieve this), then the food will be good as new when it reaches it's destination.

One of the best ways to reduce the level of oxygen within food packaging is to use Modified Atmosphere Packaging which is to replace the oxygen with an inert gas, generally Nitrogen.  This method increases the shelf life of processed foods without the need for vacuum packaging, preservatives, or freezing that might ultimately affect the end quality of the food.

Using a Nitrogen Generator for Modified Air Packaging

Using a Nitrogen Generator for the Modified Air Packaging process is an efficient and economical way to apply N2 gas.  A Nitrogen Generator produces high purity N2 gas on-site and on-demand without risk of running out and without the need for handling and storing extra high pressure N2 gas cylinders.  Nitrogen Generators use a simple PSA Generator or Membrane Generator Technology to separate and capture the N2 molecules directly from the air around us.

South-Tek Systems is a leading designer and engineer of Nitrogen Generators.  Using their unique Flow Verification Program, clients are fitted with the most appropriate sized N2 Generator for their specific application, providing efficient operation and confidence in getting the job done right.

Nitrogen Purging with a Nitrogen Generator

Nitrogen gas is often used for purging, a process that is utilized in a wide range of industries - from Gas & Oil to Winemaking and Food Packaging.

Nitrogen gas is a clean, dry, inert gas that makes up 79% of the air we breathe.  A Nitrogen Generator effectively separates and isolates the N2 molecules from the air, allowing it to be applied to an atmosphere that requires little to no oxygen for safety or preservation purposes.


Nitrogen Purging Can Eliminate Oxygen

In certain situations, Oxygen can be a highly dangerous presence, providing a vital element for combustion or corrosion.  In order to displace Oxygen and eliminate these threats, a high volume of Nitrogen gas is pumped into an atmosphere, vessel or closed system of piping with a continuous, uninterrupted flow.

Situations where combustion is a threat include aircraft fuel tanks, chemical processing, and oil and gas wells.

Situations where corrosion is a threat include a power plant boiler, HRSG layup, and fire protection systems.

Nitrogen Purging for Safety and Quality

Nitrogen purging affects not only the safety of an atmosphere, but also the quality of the overall system or final product.  As mentioned earlier, N2 gas is applied to scenarios where combustion or corrosion can undermine the safety and performance of a system or process.

But Nitrogen purging is also used to ensure the quality of a product, as in Modified Atmosphere Packaging (MAP) used with food packaging.  MAP is used to minimize the Oxygen within packaging to prevent spoilage and preserve properties such as aroma, flavor and texture of the packaged foods.

Nitrogen purging is also used with Medical Device Packaging to maintain sterility, freshness, and shelf life in an effort to preserve cleanliness and get the most accurate test results possible.

Economical and Effective N2 Purging with a Nitrogen Generator

Since N2 purging requires a continuous and uninterrupted flow of N2 gas, a Nitrogen Generator is the most economical and effective source of N2 available.  Where high pressure N2 cylinders need to be switched out with stored extras to maintain a flow - always with the threat of running out during peak use - a Nitrogen Generator supplies a steady source of high purity N2 gas on-demand at any given time.

South-Tek Systems engineers and manufactures Nitrogen Generators for applications in a wide range of industries, including all the applications mentioned here as well as many others.  Contact South-Tek Systems to learn how your business can benefit from having a Nitrogen Generator on-site: 888-526-6284.

Nitrogen for Power Plant Gas Turbine Purging

Power plant gas turbine natural gas fuel lines need to be purged during commissioning or during periodic start-up. Typically, the purge pressure required is approximately 600 PSI to provide sufficient purging during this process.

Nitrogen, being inert and extremely dry, has proven to be a safe, reliable, economical, “green” solution to providing such high pressure purge to meet the gas turbine manufacturers’ or plant operations recommended start-up procedures.

Using Nitrogen For Natural Gas Line Purging

Nitrogen has been used for years to purge high pressure lines power plant gas turbines and similar applications. Nitrogen, which makes up 79% of the air we breathe, is the perfect “green” solution for purging gas turbines. Nitrogen is inert and when you generate your own Nitrogen at your facility you can also boost the Nitrogen for storage in high pressure cylinders for later use.
  
How a Nitrogen Generator Benefits the Power Plant

In the past, power plants have purchased either banks of high pressure cylinders or liquid bulk Nitrogen to provide this form of purging protection. Today, with the installation of a Nitrogen Generator at your facility, you can generate your own nitrogen at a fraction of the cost versus purchasing Nitrogen cylinders or bulk liquid Nitrogen. Plus you can generate the Nitrogen on demand, and never run out. The Nitrogen Generator simply separates mechanically, the Nitrogen molecules from the other molecules found within the air and stores the Nitrogen until needed for your process use.

South-Tek Systems offers a complete line of reliable, cost effective Nitrogen Generators sized for your application. Using our Flow Verification Program, we are able to ascertain the specific flow rates of Nitrogen required for your facility and a Nitrogen Generator can be sized and installed at your facility accordingly, allowing you to realize the significant cost savings yielded by this technology.

Eliminating Bacteria Using Nitrogen Gas

What Is Bacteria?

Bacteria are microorganisms that grow in soil, water, and organic matter as well as living plants, animals, and people.  While most bacteria are harmless (and some are even beneficial), there are a few strains of bacteria that are pathogenic and can cause harmful bacterial infections.  Bacteria can grow and divide extremely rapidly, especially in the presence of available nutrients.

How Can I Prevent Bacteria Formation?

Bacteria, as well as mold and mildew, can start to form, grow, and reproduce in the presence of oxygen, warmth, and moisture.  Removing oxygen from an atmosphere for packaging or storage eliminates the potential for harmful bacteria growth.  This can be applied to food packaging and storage as well as chemical processing and even to sterilization for cleanrooms and medical device packaging.

Nitrogen is a clean, dry, inert gas that is often used to absorb moisture and displace oxygen in an environment.  The application of N2 gas effectively removes oxygen and prevents bacteria formation as well mold and mildew.

Why Use a Nitrogen Generator for Bacteria Elimination?

Using a Nitrogen Generator to eliminate and prevent harmful bacteria is an efficient, reliable, and cost effective solution compared to using high pressure N2 gas cylinders or bulk liquid Nitrogen.  Using a simple, straightforward PSA Generator or Membrane Generator technology to isolate and capture N2 molecules from the air we breathe, a Nitrogen Generator essentially produces high purity Nitrogen from thin air.  It is reliable and safe, easy to maintain, and won't ever run out of N2 gas.

Nitrogen Gas Uses for Clean Rooms

A cleanroom may be used in manufacturing, in the pharmaceutical industry, or in a scientific research lab.  It provides a controlled atmosphere to reduce contaminants such as airborne particles and dust.  The essence of a cleanroom is to reduce environmental contaminants by controlling air flow rates and direction, pressurization, temperature, and humidity.  This provides the cleanest possible environment for manufacturing, packaging, testing, or research.

Clean rooms may utilize inert gas systems to maintain a specific air pressure and to control humidity levels.  Nitrogen is often used as the inert gas in this scenario. 

The dry, inert properties of Nitrogen gas make it an ideal substance for other cleanroom uses.  These may include:
  • Drying parts being used in the clean room
  • Blowing off an assembled system or piece of equipment before it leaves the clean room
  • Purging a product, system, or piece of equipment for packaging
Nitrogen Generators for Cleanrooms

Nitrogen Generators are an alternative to bulk liquid N2 or high pressure gas cylinders.  A Nitrogen Generator produces high purity N2 gas on-site and on-demand and may be customized according to the flow rate capacity of the cleanroom.  It is a safe, reliable, and cost efficient source of Nitrogen gas, ideal for cleanrooms because of their need for a continuous controlled environment.

Nitrogen Use with Medical Device Packaging

The packaging of medical devices and supplies such as test kits for doctor's offices, blood supplies, instruments, and containers presents a challenge for sterilization, preservation, and extended shelf life.  Sterile packaging is a crucial factor for medical technology and devices but the packaging must also be optimal for transportation, storage, and end use.


Packaging for Medical Supplies and Devices - Challenges and Solutions

Medical supplies and devices are constantly being transported from office, hospital, or clinic to labs, or from suppliers to buyers where they are stored until needed for use.  It is imperative to maintain a sterile atmosphere within the medical supply and device packaging during transportation and storage - right up until the moment the package is opened for the end user.  Often, a medical supply being packaged is perishable and must be preserved at it's freshest state for the duration of the transportation and storage.

The challenge here is to maintain sterility, freshness, and shelf life so as to preserve the integrity of the product, to get the most accurate test results, and to extend the shelf life of medical devices and supplies.

Nitrogen gas is a clean, dry, inert gas used effectively for sterilization, preservation, and atmosphere blanketing.  Nitrogen provides an ideal solution to the challenges presented in medical device packaging.

Optimal Preservation with Nitrogen Gas

Nitrogen may be applied during medical device packaging to eliminate the presence of oxygen.  If oxygen comes into contact with perishable medical supplies, it may affect the nature of the product as well as any test results associated with it.  Nitrogen displaces the oxygen and maintains a dry, sterile atmosphere within the packaging.  Also, by eliminating oxygen, Nitrogen gas will prevent humidity levels which can affect the shelf life of stored medical devices.

A Nitrogen Generator is a safe and reliable way to administer N2 gas for medical packaging.  Especially when compared to high pressure cylinders, a Nitrogen Generator is cost effective, easily manageable, produces high purity N2 gas on-site and on-demand, and won't ever run out of gas.  Using a simple PSA Generator or Membrane Generator technology, a Nitrogen Generator is the best solution for sterile medical device packaging.

South-Tek Systems Contracts With the U.S. Military

South-Tek Systems, a company dedicated to designing and manufacturing Nitrogen Generators, has been awarded defense contracts with the U.S. military to supply their Nitrogen Generator products to different sectors of the military, including the Marine Corps.

South-Tek Systems is featured in a Wilmington, N.C. Star-News report about local southeastern North Carolina businesses who are benefiting from defense contracts with the U.S. military.  The article states that approximately 325 Wilmington area businesses hold defense contracts to do business with the military and "that the word only recently has gotten out about the enormous opportunities to make money from the U.S. government."

Charles Metzler, industrial and military sales manager for South-Tek Systems, was quoted in the article regarding his experience in getting qualified to sell to the U.S. government and then actually securing defense contracts.  South-Tek makes a big and deliberate push to promote their Nitrogen Generators to the military bases and has had success in getting their products into the hands of the Marine Corps.

Nitrogen Generators produce Nitrogen gas on-site and on-demand using a simple technology that separates and captures the N2 gas present in the air around us.  They are meant to replace delivery of hundreds of high pressure cylinders of the gas and are more efficient, reliable, and cost effective.  Nitrogen is "the most widely used gas on the market," says Metzler, and Nitrogen Generators make it easier to produce high purity N2 gas as-needed.

South-Tek Systems manufactures a range of Nitrogen Generators from the compact, portable N2 GEN Series, to the skid mounted S Series, to the high pressure HP Series.  Their generators can accommodate a wide variety of applications and can be used for the military both in the field and on the base.

Save Money, Preserve Quality Using Nitrogen for Food Packaging

Companies that specialize in food packaging require a solution for keeping the food fresh, preserving the taste and texture, and ensuring safe delivery throughout its journey from the warehouse to the shelf to the consumer.

Preserving Quality

An ideal solution to solve each of these issues is Nitrogen gas.  Using Nitrogen to blanket food packaging helps to eliminate the presence of oxygen.  Oxygen reacts with the food causing oxidation and affecting the quality, taste, texture, and safety of the product.  Food packaging companies use Nitrogen for modified atmosphere blanketing (MAP) or controlled atmosphere (CA) to eliminate oxygen that might cause bacteria or virus growth and keep food safe and preserved for consumption later in its shelf life.

Learn more about Food Packaging Using Nitrogen Gas.

Saving Money

Because large quantities of Nitrogen are required for atmosphere blanketing with food packaging, the most ideal method for administering the gas is with a Nitrogen Generator.  Nitrogen Generators help companies save money and work efficiently because they produce Nitrogen literally from thin air and will not run out of the gas supply.  Avoid costly run-outs, switching tanks, N2 gas company contracts, high pressure cylinder delivery, handling and storage all with a Nitrogen Generator.  Depending on the size and model Nitrogen Generator a company needs, they may see a return on investment (ROI) in 18-24 months, plus they eliminate the hassle of dealing with the gas company, storing extra cylinders, and potentially running out of gas at a critical point.

Wine Bottling Using Nitrogen

Wine Making Process

The process of making wine involves many steps, from growing the grapes to picking them and crushing them to get the juice or "must."  The must is then pressed, the juices extracted and poured into a vat. The next step involves settling - letting the juices settle so that the grape sediment separates and drops to the bottom of the vat.  The juices are then divided up and transferred among different vats where they will settle even more.  The next step is fermentation where yeast is added to convert the natural sugars into alcohol.  Finally, the wine is ready to be bottled.

Nitrogen Use During Wine Bottling

Nitrogen gas is a clean, dry, inert gas that is safe to handle and easily accessed with a Nitrogen Generator.  Nitrogen comprises 79% of the air we breathe and a Generator uses a simple technology to mechanically separate the Nitrogen molecules from the other molecules found in the air, isolating the Nitrogen gas in a storage tank until needed.

Nitrogen is used in the bottling phase of wine making in a couple of different ways:
  1. Sterilizing the bottles - Nitrogen is used to flush the wine bottles before and after bottling to sterilize them.  Using Nitrogen helps eliminate the need to use water in the bottles before adding the wine.
  2. Flushing the hoses - Nitrogen is pumped through hoses, pumps, and tubing just prior to bottling for sterilization and to flush out the oxygen.
  3.  Reducing Oxidation - The turbulence that results from bottling has the potential to mix a lot of air in with the wine, increasing the risk of oxidation that will turn wine stale before its time.  Oxygen reacts with a microbe found in wine and starts converting the ethyl alcohol in the wine into acetic acid, turning wine into a more vinegar-like substance.  Nitrogen works to displace the oxygen and preserve the wine during bottling.

Use of Nitrogen during wine bottling has many advantages, especially when produced using a Nitrogen Generator as an alternative to N2 gas cylinders.  The high pressure cylinders need to be handled with extreme caution and require that you rely on a gas company for refilling.  You also run the risk of running out of N2 gas with a cylinder.  A Nitrogen Generator is safe, reliable, won't run out of gas, produces N2 on an as-needed basis, and is even more cost effective than using cylinders.  You can ensure that your wine will not risk oxidation during bottling with a  Nitrogen Generator.

You may be surprised to note that Nitrogen gas can be used during many phases of wine making, not just bottling.  Nitrogen is used throughout the process of wine making, particularly during the settling phase, to eliminate the presence of oxygen and to protect against possible oxidation.  Nitrogen can also be used during the wine drinking phase to preserve open bottles of wine for a longer period of time by purging them of oxygen (see: WineLast™ Nitrogen Purging System, WineLast™ - Keep Your Wine Fresh & Tasting Great Longer)

Nitrogen Uses in the Wine Industry

Wine Barrels & Nitrogen Inerting
The amount and length of time that oxygen (found predominantly in the air all around us) is exposed to wine can influence wine quality, stability, and longevity. Nitrogen gas is used widely throughout the wine industry to eliminate the exposure of oxygen to wine for a number of applications including:
  • Bottling
  • Topping
  • Sparging
  • Flushing
  • Storage
  • Transfer from Storage to Bottling
  • and more!
Nitrogen is the preferred inert gas for these wine-making processes because of its low solubility in wine as well as for its ability to eliminate the presence of oxygen and to prevent oxygen from coming into contact with the wine throughout the many stages of production.

The problem of prolonged exposure to oxygen is that it causes oxidation, effectively turning wine into a vinegar-like substance over time.  The oxygen reacts with a microbe found in wine and starts converting the ethyl alcohol in the wine into acetic acid - the main component of vinegar!

Here are the ways Nitrogen as an inert gas is used to prevent oxygen exposure during wine making, storage, and bottling:
  1. Sparging: this is when Nitrogen (N2) is applied in the form of very fine gas bubbles in order to remove dissolved oxygen from the wine.
  2. Blanketing: the process of applying an inert Gas such as Nitrogen into a vessel to displace the oxygen is used during wine-making often to top the head space in partially filled tanks, barrels, or other containers.
  3. Flushing: just prior to bottling, air must be flushed from hoses, filter housing pumps, and the fill bowl by using a displacement gas such as Nitrogen.
Sparging, blanketing, and flushing are used during the processing stages of wine making for the following uses:
  1. Wine Transfer: when transferring wine from one container to another, Nitrogen should be pumped through the vessels for blanketing and hoses should be flushed to remove oxygen.  It may also be necessary to use sparging of the wine at this point to remove any oxygen that has already dissolved in wine.
  2. Topping: this is the process of replacing evaporated wine in the barrel. The "head space" in the barrel, also called "ullage," should be flushed with Nitrogen and then blanketed to eliminate oxygen.
  3.  Bottling: oxidation is a particular risk during wine bottling due to the turbulence and mixing of wine with air in the filling process.  It is important to flush wine bottles with Nitrogen prior to and after filling.
Nitrogen Generators are an efficient and cost effective way to eliminate the threat of oxidation during wine production and bottling and to preserve the quality of the wine.  Nitrogen Generators replace the need for handling high pressure N2 cylinders and expensive gas company contracts.  They are safe, reliable, easy to operate, never run out of Nitrogen, and generate Nitrogen as needed so they can accommodate seasonal or fluctuating production schedules.

    Protect Power Plant Boiler With Nitrogen

    A boiler is a main and crucial component of a power generating station such as a combined cycle power plant.  The boiler contains wetted parts that are at threat of corrosion during layups and outages when they may be exposed to oxygen. Corrosion due to the presence of both moisture and oxygen on uncoated, scratched or worn steel parts develops and spreads very quickly, threatening the integrity of the boiler system and resulting in time consuming and costly repairs.

    Maintain and Protect Boiler with Nitrogen

    The power plant boiler needs to be maintained and protected to prevent oxidation or corrosion.  Proper maintenance and protection may extend the service life of the boiler significantly.  While products exist to apply protective coatings to the steel and chemical inhibitors exist to prevent corrosion, these are neither fully reliable nor environmentally friendly options.  They may also be expensive, requiring regular coatings and applications.

    Using Nitrogen gas to inert the wetted parts of the power plant boiler is both a reliable and environmentally friendly solution to fight and prevent corrosion.  Nitrogen is a clean, dry, inert gas that, when pumped through the system, works to absorb excess moisture and displace oxygen, thereby eliminating the factors necessary for corrosion to develop.

    A Nitrogen Generator is Safe, Reliable & Cost Effective

    Applying N2 gas to the wetted parts of your power plant boiler using a Nitrogen Generator is also safe and cost effective, requiring a one-time installment and minimal annual maintenance.  It is easy to operate and the professionals at South-Tek Systems can ensure that you are fitted with the most appropriate sized Generator for your needs through the Flow Verification Program.

    South-Tek Systems engineers and manufactures Nitrogen Generators for a variety of applications across diverse industries, including the energy and power plant industry (See: South-Tek Systems Supplies Nitrogen Generators for Power Plant).

    Nitrogen for HRSG Layup

    An HRSG (heat recovery steam generator) used in a combined cycle power station or cogeneration power plant is an essential element for energy production in these plants. It is imperative to maintain the HRSG component during layups while at the same time limiting its exposure to oxygen and keeping it free from corrosion that can be detrimental to the overall performance of the HRSG and the power plant. In fact, proper maintenance of the HRSG can be the best determining factor of the longevity and reliability of the plant.

    How To Maintain the HRSG

    When a power plant undergoes regularly scheduled layups for maintenance and upgrades, the HRSG must be properly maintained.  One of the biggest dangers during this time is exposure to oxygen which, when mixed with moisture and steel, can quickly cause corrosion, or oxidation.  Preventing this exposure to oxygen is imperative to maintaining the integrity of the unit and extending the life of the power plant.

    Chemical inhibitors have traditionally been used to prevent block the introduction of oxygen.  However, these materials can be dangerous to handle and harmful for the environment.

    Nitrogen Use During HRSG Layup

    An alternative to using chemical inhibitors is to use clean, dry, inert Nitrogen gas pumped through the tubes and wetted parts.  This process of inerting the HRSG using Nitrogen gas is a reliable and environmentally friendly solution to preventing oxidation and corrosion.

    A Nitrogen Generator is a safe and cost effective alternative to using high pressure N2 gas cylinders to deliver Nitrogen to the system.  Nitrogen Generators are installed one time, are easy to maintain and operate, and are extremely effective at preventing corrosion.

    Nitrogen for Power Plant Outages and Layups

    Power plant outages occur when one or more power generation units have to shut down for routine maintenance, repairs, or upgrades. It is inevitable in the life-cycle of a power plant to have shutdowns or outages but there are concerns for the preservation of the equipment during these layup stages.

    What Happens During A Power Plant Layup?

    When a power plant boiler is drained for maintenance or upgrades, residual water will likely remain in the boiler tubes and condensers.  This water will mix with the oxygen from the air it is exposed to during the layup and any worn or scratched parts of the steel tubing that are affected by this mix are immediately susceptible to corrosion, or oxidation, of the tubing.

    This corrosion of the wetted parts of a power plant that occurs during outages and layups can cause pinhole leaks, threatening the integrity of the parts, leading to further damage and costly and time consuming repairs.

    Once the process of corrosion begins, it spreads rapidly throughout the susceptible parts of the system.  These are the parts that mix unprotected (scratched or worn) steel tubing, moisture, and oxygen.  Galvanic corrosion and microbiologically influenced corrosion can both spread quickly and cause real damage to the inner workings of the power plant.

    How to Protect the Power Plant During Outages

    Power plants and their susceptible parts can be protected from the development of corrosion during outage and layups.  One solution is to inert the wetted parts (boiler tubing, condensers, etc) using Nitrogen gas.  The process of inerting will displace the oxygen with Nitrogen, eliminating an environment where corrosion can occur.

    Nitrogen is a clean, safe, inert gas that can be provided conveniently and reliably by a Nitrogen Generator.  South-Tek Systems is an engineering and manufacturing company dedicated to Nitrogen Generators.  They possess the knowledge and experience to apply the use of Nitrogen Generators with power plant facilities (See: South-Tek Systems Supplies Nitrogen Generators for Power Plant). 

    A Nitrogen Generator is a cost effective, safe, and reliable alternative to high pressure N2 cylinders.  Not only are they an environmentally friendly choice, but, once installed, they require minimal maintenance.  They use a simple PSA Generator technology that produces Nitrogen literally from the air around us. 

    South-Tek Systems can fit your power plant facility with a properly sized Nitrogen Generator for your needs using the unique Flow Verification Program.

    Power Plant Corrosion Control


    Corrosion of wetted parts in power plant facilities - such as in boiler tube inner walls and condensers - presents a very real threat to the performance of the entire power plant.  Corrosion, or oxidation, can compromise the integrity of the boiler tubes and condensers resulting in leaks, cracks, and, ultimately, failure.  It is crucial to implement power plant corrosion control to protect the wetted parts, reduce costly and time consuming maintenance, and optimize the performance of the facility.

    How Does Power Plant Corrosion Occur?

    Corrosion in power plants occurs when three things come into contact:
    1. steel
    2. oxygen
    3. water
    The most common area for corrosion to develop is within the wetted parts where all three of these elements come into contact.  Steel tubing that is exposed to moisture from water and oxygen from the air will develop oxidation or galvanic corrosion.

    When a power plant boiler goes through a drain-down for repairs or maintenance, it is inevitable that both residual moisture will remain and the tubing will be exposed to oxygen from the air.  The result is the ideal formula for the development of corrosion.

    Power Plant Corrosion Control

    One solution to prevent the development of corrosion is to use inert nitrogen gas to displace oxygen.  Nitrogen gas pumped through the system works to eliminate oxygen AND absorb moisture to prevent the development of corrosion.  Nitrogen is an inert, clean, dry gas that has become a more popular alternative to chemical inhibitors because it is an environmentally friendly option.

    There are two ways to obtain a Nitrogen gas supply: high pressure gas cylinders and Nitrogen Generators.  Nitrogen Generators are the optimal choice because they produce a steady stream of nitrogen gas, on-site and on-demand.  Once you install a Nitrogen Generator in your facility, there will be no change-outs, no gas company contracts, and only minimal maintenance.  They are a safe, reliable, and cost effective option for power plant corrosion control.

    Contact South-Tek Systems for Your Nitrogen Generator

    South-Tek Systems engineers and manufactures Nitrogen Generators for use with various applications across a variety of industries, including Power Plants.  They have direct experience in this field (see: South-Tek to Supply Nitrogen Generators at Combined Cycle Power Plant) and can assist with designing and providing the ideal generator for your plant - from a small industrial boiler, to an HRSG combined cycle power plant, to a large gas, oil, or coal fired power plant.

    Prevent Corrosion in Power Plant Boiler Tube

    Boiler tubes used in power generating plants and the heating and ventilating industry are part of the  tubing components of utility and industrial boilers. The boiler tubes are generally constructed of steel, are heated and exposed to water within the boiler to generate steam.  In the case of a power generating plant, this steam plays a vital role in the production of electricity.

    Due to the construction and use of power plant boiler tubes, these integral pieces of equipment are susceptible to corrosion resulting in poor performance, costly repairs, and, ultimately, failure.

    Why Are Power Plant Boiler Tubes Affected By Corrosion?

    The combination of steel, water, and dissolved oxygen in the boiler water initiates the corrosion, or oxidation, of the boiler tubes.  This corrosion leads to grooving in the tubes and eventually cracking that causes the failure.

    Although the boiler is a closed vessel, it has been found that oxygen is introduced during the addition of water (make-up water) after a drain down for interior projects or repairs.  This water treatment method aerates the boiler water and actually promotes boiler tube corrosion.

    How To Prevent Boiler Tube Corrosion

    The elimination of one of the above elements - steel, water, or oxygen - can help prevent this type of corrosion and damage to the power plant boiler tubes.  

    Since steel is the optimal material for boiler tube construction because of its ability to handle heat and water is of course necessary to the power generating process, it would be ideal to eliminate oxygen from this equation.

    One solution for eliminating oxygen is to inert the atmosphere in the boiler using nitrogen.  Nitrogen inerting works to displace the presence of oxygen in the vessel with nitrogen gas.  Nitrogen is a clean, dry, safe gas often used for the purpose of eliminating oxygen where the presence of oxygen can cause either combustion or corrosion.

    Nitrogen Generator for Boiler Tube Corrosion Prevention


    South-Tek Systems designs and manufactures Nitrogen Generators for the purpose of purging and inerting for a wide variety of industries and applications.  Nitrogen is a safe, reliable, cost effective solution for maintaining power plants to keep them running smoothly and efficiently for maximum performance.

    Nitrogen Generators provide an easier and more ideal alternative to high pressure nitrogen cylinders.  A generator can safely and reliably produce high purity N2 gas on-site and on-demand for a fraction of the cost of the managing high pressure cylinders.

    Nitrogen Use with Pneumatic Tools

    Pneumatic Tools, also known as air tools, are tools powered by a compressor that forces air into a tank where it becomes pressurized.  The tool is then hooked up to a pneumatic air hose attached to the tank through an air valve.  Once the tool is connected to the hose and the valve is opened, the pressurized air is then forced into the tool.

    Pneumatic tools are widely used for industrial purposes but have also crossed over into household use.

    Traditionally, the air compressor powering the pneumatic tool is gas powered.  However, there is a growing movement to use Nitrogen gas to power these tools.  The benefits are that you can eliminate the exhaust smell and residue associated with the gas powered version and power the tool with compressed Nitrogen gas that will be used to drive the release valve or firing pin.

    Using a Nitrogen Generator, the N2 gas for the tool can be recycled and used over and over.  This is a safe, clean, efficient alternative to the gas powered compressor.  It is also cost-efficient, requiring a one-time purchase with no cylinders to refill.  A Nitrogen Generator produces high purity N2 gas on-demand and on-site.

    Plastics Extrusion with Nitrogen Treatment

    Plastics Extrusion is the process of melting raw plastic material to create a long, continuous shape which may be used for piping, tubing, weather stripping, and more.  Plastics Extrusion can also be used in the recycling process where the plastic material to be recycled is melted into long strips, cooled, and then shaped for new materials or cut into resins and packaged.

    The cooling stage of Plastic Extrusion can be made more streamlined and efficient using Nitrogen gas as a cooling agent.  Nitrogen - a clean, dry, inert gas - has the ability to cool very quickly and set the desired shape for the plastic being treated.  It is a safe and effective method to apply to the Plastics Extrusion process.

    See more info on Plastic Extrusion Nitrogen Gas Purge.

    When using Nitrogen gas during Plastic Extrusion, consider investing in a Nitrogen Generator to ensure a continuous supply of Nitrogen on-demand and on-site as needed.  A Nitrogen Generator produces high purity N2 gas in a more safe and convenient package compared with high pressure N2 gas cylinders.

    You'll never run out of Nitrogen again with a Nitrogen Generator plus it yields a high Return on Investment (ROI) especially compared to cylinders supplied through a gas company contract.

    Nitrogen for Power Plants

    Threat of Corrosion to Power Plant Equipment

    Corrosion, as we all know, shortens the life of power plant process equipment. The internal protection from corrosion of boiler tubes, condensers, and wetted parts within small industrial boilers, HRSG combined cycle power plants, and large gas, oil, and coal fired power plants is extremely important during short term layups, right on to the long term plant outages. Without a form of protection, during the shutdown, corrosion can occur on these wetted parts at an alarming rate.

    Chemical Solution - Harmful to the Environment

    One solution, if the water is able to be circulated within these power plant parts during shut down, is to inject chemical inhibitors into the water stream. But introducing such chemicals into the system has become less desirable as the disposal of such presents environmental issues. If the water is drained from the wetted parts, residual water remains within, and along with oxygen (air) introduced during the draining process, corrosion begins.

    Nitrogen Solution - The Environmentally Friendly Answer

    Nitrogen has been used for years to protect against corrosion in power plant equipment and similar applications. Nitrogen, which makes up 79% of the air we breathe, is the perfect “green” solution for corrosion protection in power plant equipment. Nitrogen is inert and, by displacing the oxygen within the wetted parts with a low pressure slow flow Nitrogen purge, you ultimately inhibit the oxidation/corrosion process.

    In the past, power plants have purchased either banks of high pressure cylinders or liquid bulk Nitrogen to provide this form of corrosion protection. Today, with the installation of a Nitrogen Generator at your facility, you can generate your own nitrogen at a fraction of the cost versus purchasing Nitrogen cylinders or bulk liquid Nitrogen. Plus you can generate the Nitrogen on demand, and never run out.

    How Does a Nitrogen Generator Benefit the Power Plant?

    The Nitrogen Generator simply separates mechanically, the Nitrogen molecules from the other molecules found within the air and stores the Nitrogen until needed for your process use. South-Tek Systems offers a complete line of reliable, cost effective Nitrogen Generators sized for your application. By using our Flow Rate Verification System and knowing the flow rates of Nitrogen required, a Nitrogen Generator can be sized and installed at your facility accordingly, allowing you to realize the significant cost savings yielded by this technology.

     PSA N2 Series Nitrogen Generators

    South-Tek Systems' Pressure Swing Adsorption (PSA) Technology in our N2-Series Nitrogen Generators produces high purity N2 gas in a safe, reliable, convenient, and cost effective process.  These systems provide great benefits to the power industry and are easy to integrate and maintain.
