Optics Purge with Nitrogen

Optical instruments rely on nitrogen for a process known as "purging." This process ensures that the optical lenses remain fog-proof or water-proof. Purging with N2 gas can apply to a variety of optical instruments, including night vision goggles, binoculars, cameras, microscopes, telescopes and more.

Many of the products that rely on nitrogen gas for optical purging are used by the U.S. military. Soldiers in the field rely on a variety of optical equipment for a number of operations. For example, soldiers regularly rely on night vision goggles to guard bases, plan maneuvers and scout out the enemy. In order to keep their goggles from fogging, soldiers must regularly purge them with nitrogen to eliminate contaminants and moisture. Compact, portable Nitrogen Generators are designed specifically for this purpose. These generators provide a lightweight, safe and reliable solution to optics purging in the field.

See news about the N2-GEN portable Nitrogen Generator completing the U.S. military EMIP review process.

Using nitrogen doesn't just prevent the optical equipment's lenses from fogging on the outside. The benefits of using nitrogen to purge optical equipment also include preventing internal fogging, creating a waterproof environment, and preventing the formation of mold and mildew. Filling optical equipment with nitrogen replaces the naturally occurring oxygen and prevents the accumulation of moisture, which can not only fog the equipment, but can also lead to the development of mold or fungus.

After the equipment is purged with nitrogen, it can then be sealed to further prevent any accumulation of moisture. The sealing process makes nitrogen-purged equipment waterproof, preventing moisture from entering the area around the lenses and putting a proactive halt to the growth of microorganisms that thrive in moist environments. Mold, fungus and mildew develop most rapidly in warm, moist enclosed spaces. Using nitrogen to purge and then seal optical equipment is the most effective solution to preventing these unwanted effects. And the most cost-effective, reliable way to purge optical equipment could be with a portable Nitrogen Generator from South-Tek Systems. Whether being used in military operations, field research, or mass-production factories and laboratories, South-Tek Systems can deliver an on-site Nitrogen Generation System that provides you with a never-ending supply of high-purity N2 for safe, effective use.

South-Tek System's portable Nitrogen Generator can offer easy, quick optical purging for uses in a variety of industrial, military or consumer settings.

Nitrogen Gas Use in the Aerospace Industry

In the aerospace industry, nitrogen gas can be used to pressurize certain components of industrial autoclaves. Because nitrogen is an inert gas which prevents the possibility of combustion, it is an ideal choice for systems that operate under high temperatures or high pressure.

See: Nitrogen Gas and Aerospace Manufacturing

Autoclaves apply heat and pressure to the workload placed inside of them. There are two common types of autoclaves: ones that utilize steam and ones that utilize heated gas. For workloads that can be exposed to moisture, steam is usually an acceptable choice. However, for workloads that require a dry atmosphere, gas is the optimal choice. Furthermore, applying gas to the pressurization of the autoclave ensures greater control and regulation of the heating atmosphere.

With gas pressurization in industrial autoclaves, nitrogen provides a more versatile operation by eliminating the presence of air, moisture and other contaminants. Because nitrogen is non-combustible, it provides a safe alternative to compressed air.

Nitrogen can also be used in ejector pumps when processing aerospace parts in autoclaves. Nitrogen can be introduced to remove nearly all of the air in a safe and effective manner. Because safety is a great concern during the manufacturing and processing of autoclave curing, nitrogen is a popular choice due to its inert properties.

Nitrogen can also be a cost-effective solution for large and expensive workloads. Because nitrogen is readily available, even possible to generate from the surrounding air we breathe, it's an accessible gas to use for large-scale projects.

To learn about how nitrogen gas can benefit aerospace industrial manufacturing as well as other industrial and commercial applications, visit the South-Tek Systems' nitrogen gas applications or call 888-526-6284.

Nitrogen Gas for Transmission Lines

When you combine the presence of oxygen, moisture, and certain other materials, corrosion can occur. This corrosion can cause long-term damage and ruin the structure and operation of various mechanical and industrial components. Transmission lines are no exception.

In addition to corrosion, transmission lines can also be vulnerable to voltage arcs and oxidization when oxygen and moisture are present. Not only will these problems jeopardize the integrity of the lines, the equipment and broadcasted end product can also be compromised.

The best way to prevent these inconvenient and often costly issues is to utilize Nitrogen gas. By positively pressurizing the transmission line with supervisory Nitrogen generated by South-Tek's N2-GEN® TL Series - Arc Suppression System, the dew point within the line can be kept lower than the temperature of the line itself. This effectively displaces the oxygen and moisture and greatly reduces the risk of voltage arcs, corrosion and other problematic reactions.

This system can also be equipped with our AutoPurge System and BlastOff Leak Detection System, to further enhance your Nitrogen Generator's performance. The AutoPurge System is designed to control positive pressure within the transmission line and maximize the life of the overall Nitrogen Generation System. The BlastOff Leak Detection System comes standard equipped with every N2-GEN Nitrogen Generator from South-Tek Systems. It allows the user to know immediately when there is a leak or when the system is running excessively to compensate for the leak. This can help detect leaks before they become significant and alert the user so they can address the issue right away.

You can learn more about the N2-GEN® TL Series - Arc Suppression System and other Nitrogen Generation products by visiting our website, downloading the N2-GEN Arc Suppression System Brochure, or by contacting us directly at 888-526-6284.

Prevent Threat of Film Oxidization & Separation

Believe it or not, Americans are still pretty regular consumers of film, which is why production facilities must continue to maintain optimal levels of manufacturing and storage to ensure the quality of their products.

Did you know that last year, 35 million rolls of film sold in North America? Not only that, but 13 million blank VHS and cassette tapes sold in America, too, proving that not everyone relies on Netflix and Pandora for their entertainment needs(source). Although most of the world has turned to digital media for capturing images and sounds, data from the Consumer Electronics Association and research firm NPD prove that the film manufacturing industry is alive and kicking.

In order for manufacturing plants to produce quality film products, the atmosphere of the facility must be optimized for the unique needs of film production. In most scenarios, nitrogen gas is used for this optimization. Nitrogen is released into the atmosphere of the production facility, creating a clean, dry, inert environment. The major concern when it comes to film manufacturing is the elimination of moisture during the printing process. Moisture can cause film to oxidize or separate, ruining the film product and causing the facility to lose money.

How Does Nitrogen Work to Prevent Oxidation?

As Nitrogen is released into the atmosphere, it effectively displaces moisture and oxygen. And since the dew point of nitrogen is extremely low (between -40 and -100 degrees F), there's virtually no chance of the nitrogen liquefying.  Because nitrogen is also an inert gas, it is considered one of the safest gases you can use in industrial applications.

To receieve the full benefit of using nitrogen in your film manufacturing facility, consider investing in a Nitrogen Generation System. Unlike having to rely on expensive, high-pressure cylinders, a Nitrogen Generator actually pulls Nitrogen from the air we breathe. These generators provide high-purity Nitrogen on-demand, 24/7. No more handling dangerous cylinders and no more risk of running out during peak operational hours.

South-Tek Systems is a leading manufacturer of Nitrogen Generators. We have a full range of systems, with model series for just about any type of industrial or manufacturing application. For more information on how a Nitrogen Generator from South-Tek Systems can improve the safety and efficiency of your facility, please call (888) 526-6284.

Use of Nitrogen Generators at Power Plants

Close-up of N2-GEN LPS225 Installation
Power plants use Nitrogen Generators for multiple applications.  Here, we'll discuss some of the more common applications as well the reasons that plant managers choose Nitrogen Generators as their preferred N2 gas source.

Power Plant Applications

Nitrogen Purge for HRSG Wet and Dry Boiler Lay-Up - Corrosion is a real threat to the performance, safety, and longevity of boilers and boiler tubes at power plants. Nitrogen is an inert gas that protects against the corrosion of inner walls of boiler tubes, condensers and wetted parts. N2 gas works to displace the presence of oxygen, one of the key players in the corrosion triangle, thereby effectively inhibiting the formation of corrosion. When the boiler units are offline during a lay-up, Nitrogen Generators provide an N2 blanket in the boiler drums.
Case Study: A Power Plant in Northeastern United States recently installed a South-Tek Systems' Nitrogen Generator in two of their combined cycle facilities after realizing the possibility of corrosion in their boilers. The capacities of the plants are 407 / 500 Megawatts and are used for dry and wet lay-ups with one volume purge every 24 hours. One of the facilities is a peaking facility, so the Nitrogen Generator will run more frequently. When the units are offline, they provide a N2 blanket in the boiler drums. The Nitrogen Generator is also used to blanket on the tube side of the feedwater heater during extended outages. Their other plant is a base loaded plant, so the Nitrogen Generator is used for boiler drum blanketing when the unit is offline for an extended period of time. With a Nitrogen Generator in place, operations are running smoothly and their concern for corrosion no longer exists.
Ammonia Purge - Some Power Plants use Nitrogen Generators for blanketing ammonia storage tanks. Nitrogen is connected to the ammonia storage tank's vapor space to provide a nitrogen blanket on the system. The intent of using a nitrogen blanketing system on aqueous ammonia tanks is to prevent the ingress of air to the tank vapor space during low ambient temperature conditions when the vapor pressure of the ammonia drops below atmospheric pressure.

Natural Gas Purge - An increasing number of Power Plants are utilizing natural gas. When a leak occurs, the site evacuates natural gas using Nitrogen within the piping system before repairs are made to reduce the possibility of explosions. When performing this procedure, the nitrogen fill valve is opened to pressurize the pipe. A pressure gauge is used to monitor pressure loss and check for leaks. Precautions are taken when releasing the purged gas into the atmosphere such as proper ventilation. Being inert, Nitrogen reduces the risk of explosions and extends the life of Power Plant equipment.

Why Use a Nitrogen Generator?

Nitrogen Generator equipment is increasingly used in power plant applications due to the ability to produce an unlimited supply of Nitrogen on-demand at the facility, eliminating missed deliveries, escalating costs and contracts. This equipment is also a convenient, safe, and more reliable alternative to delivery and handling of bulky, compressed gas cylinders or tanks.

Using Nitrogen in Animal Feed Storage

When it comes to storing perishable products like animal feed, oxidation and moisture control are ongoing concerns for facility managers. The use of Nitrogen gas in animal feed storage can prevent oxygen from entering the storage atmosphere and greatly reduce the chance of moisture entering the containers.

How Does Nitrogen Gas Help with Animal Feed Storage?

By displacing moisture and reducing the oxygen levels in feed storage, facilities can prevent the product from going bad and also lengthen the feed's shelf life. After all, it may take days or weeks before the feed reaches the consumers, so maintaining optimal storage conditions is a must. Nitrogen works to preserve the feed's quality and lengthen shelf life by taking the place of oxygen in the packaging and/or storage material. This can be done through the assembly process by pumping Nitrogen into the containers from a direct line.

Why Use a Nitrogen Generator?

In years past, many animal feed facilities relied on expensive gas cylinders to store their Nitrogen supply. This usually required high-dollar yearly contracts with gas suppliers. Also, it left the facilities vulnerable to run-outs during peak production times. Modernly, more facilities are turning to on-demand Nitrogen through revolutionary Nitrogen generators. These generators are installed at the point of process in the facility and produce Nitrogen gas from the surrounding air. Because the Nitrogen supply is directly pulled from the air we breathe, there's little to no chance of ever running out. This not only keeps the facility operating efficiently and safely, it can save the facility hundreds of thousands of dollars annually.

Contact South-Tek Systems 

South-Tek Systems is a leading manufacturer of Nitrogen Generators. We offer a wide selection of N2 generation systems to suit a variety of industrial and manufacturing applications. Animal feed storage is just one of the many applications in which Nitrogen generators can be used. Wine storage, absorbent materials production, metal parts production, fire protection systems and laboratory applications are some of the other industries that can benefit from an on-site Nitrogen Generator.

Contact South-Tek Systems today to learn more or to request a free cost analysis for your facility. You might be surprised to see just how much money your company can save by switching to a Nitrogen Generator. Call (888) 526-6284 to learn more about how a Nitrogen Generator can benefit your storage facility.

Bottling with N2 Gas

In the food and beverage industry, bottling is used for a wide array of storage solutions. From bottled beverages to medicines to cleaning products and more, there are lots of modern products that are packaged and stored in bottles. To prevent the product inside the bottle from going bad, manufacturers often use Nitrogen gas to displace oxygen and moisture. The most efficient way to do this is with the use of a Nitrogen Generator (See more: Bottle Manufacturing with Nitrogen Gas).

Nitrogen Generators create an on-demand supply of N2 gas from the surrounding air. This prevents the risk of accidental run-out during critical operation times and can be significantly less expensive than relying on high-priced contracts with gas suppliers.

Because Nitrogen is a dry, inert gas, it is the best choice for preserving and storing bottled products. Here are just a couple reasons why:
  • The dew point of Nitrogen is extremely low, which means there is very little chance of moisture developing within the bottle when Nitrogen is used to displace the oxygen. 
  • Its inert properties prevent it from being combustible, which makes it a very safe gas to work with in a manufacturing environment.
Without the use of Nitrogen, the risk of oxidization is greatly increased. Oxidization is a reaction that occurs when oxygen and moisture are present. In the bottling process, if moisture and oxygen are present, the quality of the bottled product can be compromised. Mold may grow, the product may lose its effectiveness, taste may be altered or carbonation could be affected. By using Nitrogen to displace the unwanted elements, the product can be preserved to increase shelf life and the consumer can be satisfied.

A Nitrogen Generator installed at the point of process allows the bottling facility to reduce production costs, maintain environmental safety and help keep the operation running smoothly. Many manufacturing facilities are surprised to learn just how much money they can save by switching to a Nitrogen Generator from South-Tek Systems. South-Tek Systems is one of the leading manufacturers of on-demand Nitrogen generation systems. They offer free cost analyses to help facilities see how much they could potentially save by switching from high-pressure N2 cylinders to an on-site N2 Generator.

Absorbents and Nitrogen Generation

Nitrogen is commonly used in a wide variety of manufacturing and industrial applications. One such use for this safe, dry gas is to create a low moisture environment for manufacturing.

An environment that is low in moisture is often critical to the successful production of various products. Absorbent products, for example, typically require zero to very little moisture in order to be produced effectively. Nitrogen can be used to safely and efficiently reduce moisture in the manufacturing environment to ensure the absorbent products are created with the best quality before being shipped to outlets and consumers. Disposable diapers, sanitary pads or other products used to absorb moisture are some of the most common examples of products that require low moisture environments to be produced.  Learn more about Nitrogen Use with Absorbent Products.

So where does Nitrogen come into play? 

Because Nitrogen gas is non-combustible, it can be used to safely inert transportation lines and storage vessels within a manufacturing facility while the absorbent material is assembled into the final product. Companies that use Nitrogen either receive their supply from a Nitrogen gas supplier or they can choose to invest in a Nitrogen generation system that produces high purity N2 gas at the point of process without the hassle of refills and cylinder changeouts. Over the years, more companies have chosen to install Nitrogen generators, as these provide a more efficient way to access Nitrogen gas.

Benefits of a Nitrogen Generation System

Other benefits of a Nitrogen generation system include:
  • eliminating the risk of running out of N2 gas during peak production times,
  • eliminating the need to handle high-pressure Nitrogen cylinders
  • producing a more cost-effective solution to manufacturing needs
With an on-site N2 generator, the supply of Nitrogen is created from the surrounding air, which means the facility will have an on-demand Nitrogen supply.

Significantly Reduce Production Costs

Back in 2008, one diaper manufacturing facility switched to a Nitrogen generator from South-Tek Systems. They also purchased three new air compressors and added an air handling room to their plant. Before the installation, this company was paying between $300,000 and $350,000 per year for their Nitrogen gas costs. After installing the Nitrogen gas generator from South-Tek System, their cost was dramatically reduced to less than $30,000 per year.

In these tough economic times, reducing manufacturing costs is something nearly all companies are concerned about. Because manufacturing has long been a cornerstone of the U.S. economy, it makes sense for facilities to seek out the newest and most advanced technologies to help keep production moving efficiently and at a low cost. By switching to a Nitrogen generator, a typical manufacturing facility is likely to see a major boost to their bottom line. This can not only work as an important part of an overall cost-reduction plan, it could pave the way for further economic growth in other areas, including employee salaries, new hires, increased production, expansion and more.

Just think of what your company could do with an extra $320,000 per year!

Maintaining Clean, Dry Metal Parts using Nitrogen Gas

In the metals manufacturing industry, maintaining a clean, dry environment is critical. The presence of moisture can lead to rust, oxidization, or corrosion, all of which can damage the metal parts and reduce the quality of metal products. The best way to eliminate the risk of moisture is through the application of nitrogen gas - a clean, dry, inert gas.

When metal parts are manufactured, they are often covered in dirt and small bits of debris leftover from the production process. These impurities have to be washed away before the parts are packaged and shipped to the customers. After the parts are washed, they need to be dried quickly to prevent moisture from accumulating and reacting with oxygen. This reaction is what causes oxidization, corrosion or rust.

Most facilities use Nitrogen gas in the drying process instead of compressed air, as it does not create the same, unwanted reaction when it encounters water. Nitrogen displaces the presence of Oxygen, eliminating it completely, and thereby eliminating any harmful reaction with water and breaking up the corrosion triangle.

The drying process using N2 gas provides a completely moisture-free environment for the metal parts, as it displaces existing Oxygen molecules with dry Nitrogen gas. The dry quality of Nitrogen is due to the fact that nitrogen's dew point (the point at which it becomes a liquid) is extremely low. The dew point of Nitrogen typically ranges between -40 and -100 degrees F, which means it's virtually impossible for it to liquefy in a controlled manufacturing setting.

The only drawback to using Nitrogen for metal manufacturing is the safety risk associated with handling high-pressure Nitrogen cylinders. Thankfully, +South-Tek Systems  provides a more modernized, efficient, and safe method for Nitrogen application - Nitrogen Generation Systems. Instead of having to rely on the gas company to bring your Nitrogen supply to you, a Nitrogen Generator from South-Tek Systems can provide you with high-purity N2 gas on-demand, 24/7. Because Nitrogen Generators create Nitrogen from the surrounding air, there's little chance that your facility will run out and those expensive and dangerous N2 cylinders will become a thing of the past.

To learn more about how Nitrogen Gas can benefit your facility and help inhibit metal corrosion, call South-Tek Systems at (888) 526-6284.

Nitrogen Gas for Food Packaging

In the food packaging industry, the use of nitrogen can be applied to a number of different processes. Not only is nitrogen a safe, inert gas - with a nitrogen generation system, it can be generated from the surrounding air without your facility ever having to worry about changing out expensive high-pressure cylinders.

Here's a look at some of the many ways the food packaging field can benefit from nitrogen gas:

1. Purging

Food packaging facilities often use a purging technique to displace oxygen from the storage container. This is typically done before the packaging is sealed, making sure that little to no oxygen is trapped in the container. This helps preserve the food's freshness, taste and shelf life. See more: Nitrogen Purging with a Nitrogen Generator
2. "Padding"

Nitrogen can also be used to "pad" the contents of a food package to prevent the package from collapsing and damaging the food products within it. Items like potato chip bags are often padded with nitrogen to maintain the right level of pressure and keep the chips from breaking during transport.

3. Modified Atmosphere Packaging

Modified atmosphere packaging is a type of purging process in which the internal composition of a package is altered to improve shelf life. This is commonly done in the food packaging industry, but it is also common in the packaging of pharmaceuticals. This process lowers the amount of oxygen in order to slow the growth of aerobic organisms as well as oxidation reactions. The displaced oxygen is very commonly replaced with nitrogen, although carbon dioxide is used in some industries. See more: Modified Atmosphere Packaging (MAP)
4. Vertical Form Fill

Vertical form fill packaging is a specific type of padding process in which a package is created and then inflated with a gas such as nitrogen. In facilities that use assembly line packaging machines, vertical form fill sealing is commonly used to store foods in plastic bag containers. During the final process of vertical form filling, an inert gas (commonly nitrogen) is used to inflate the bag. This is helpful in protecting the foods or liquids during transport. See more: Vertical Form Fill Packaging with Nitrogen
5. Controlled Atmosphere Storage

In controlled atmosphere storage, the air composition surrounding the food product is regulated. Additionally, the temperature and humidity levels are controlled to prevent decomposition and enhance the product's shelf life. The two main products that benefit from controlled atmosphere storage include fresh fruits and dry commodities like grains, oilseed and legumes. The use of nitrogen in this scenario helps control the threat of insects and other pests, which cannot exist indefinitely without the presence of oxygen. See more: Controlled Atmosphere Storage Using Nitrogen
The most effective and economical way to use nitrogen in food packaging is typically through a nitrogen generator. Instead of having to rely on high-pressure, expensive nitrogen cylinders, a nitrogen generator creates its own supply of nitrogen from the surrounding air. This helps facilities maintain the supply of nitrogen they need to function at optimal levels while also reducing the risk of combustion from other types of gases. Nitrogen's dry, inert properties have made it the more popular choice for food packaging as well as other manufacturing and storage industries.

Nitrogen Blanketing System

Tank blanketing is a process used by various industries to prevent air, moisture and other contaminants from entering a storage container. This is done by introducing an inert gas into the container, which displaces oxygen and thereby reduces or eliminates the risk of moisture condensation and other elements that could compromise the quality of the product.

Benefits of Using Nitrogen Gas

Nitrogen is considered the most effective gas for use in tank blanketing, due to its non-combustible properties. Some of the most common uses for blanketing with nitrogen include:
  • the prevention of oxidization in cooking oils and other liquids
  • preparation of products for transport
  • final packaging of food products
  • prevention of harmful contaminants entering the storage space. 
Oxidization is a major concern for many industrial facilities, as the presence of oxygen can react unfavorably with different materials, thereby altering the product's quality. The presence of oxygen can significantly affect the quality, taste or functionality of various products, which is why tank blanketing is such an important part of the manufacturing and packaging industries.

Nitrogen Generators in the Lab

In a working laboratory, maintaining ideal atmospheric conditions is crucial. Not only does a laboratory need to have a clean, controlled environment, it also needs to be safe - particularly those laboratories that house hazardous materials.

One of the most common ways labs maintain a clean, safe, controlled atmosphere is through the application of Nitrogen gas. The ideal way to handle this kind of atmosphere blanketing is by using Nitrogen Generator systems that create their own supply of high purity N2 gas from the surrounding air right at the point of process. Labs that use a Nitrogen Generator system will never have to rely on high-pressure gas cylinders. Facility managers won't have to waste time and money changing them out, ordering more, or storing them. And because labs often require a large amount of Nitrogen to maintain the correct atmospheric conditions, having a Generator in the lab can save time, money and improve the functionality of the facility and its equipment.

Speaking of equipment, labs are full of highly-sensitive, expensive devices that scientists and technicians rely on to conduct their research and produce certain conditions. In order to maintain the value, functionality and safety of the equipment, the surrounding atmosphere must be controlled. Nitrogen allows for more control in a laboratory environment, since it is clean, dry and inert. Nitrogen gas is applied to control the levels of oxygen, humidity, and temperature for a wide range of lab equipment. Cell incubators, IVF incubators, dry boxes, glove boxes, and mass spectrometers are some of the most common types of equipment that need specific atmospheric conditions in order to maintain their optimal level of use.

Without Nitrogen gas (or another agent that diminishes the presence of oxygen), moisture can occur, leading to contamination, corrosion, mildew, or other damaging effects. Nitrogen gas can also help maintain certain temperatures, which is important in a lab environment, as many materials have different reactions depending on how much heat is present.

Because oxygen can be harmful if it reacts with other gases or materials, displacing the oxygen in certain conditions can create a more stable, safe environment for lab work. Nitrogen is a clean, dry, inert gas that can reduce or eliminate the risk of combustion, corrosion, oxidation and other unfavorable effects.

Unfortunately, some facilities still rely on using tanks of liquid nitrogen that require delivery, storage and handling of hazardous cylinders. Thankfully, South-Tek Systems has a line of high-quality, affordable Nitrogen Generators available for laboratories and medical facilities. Through either simple PSA or Membrane technology, South-Tek Systems' Nitrogen Generators do not have to rely on high-pressure storage tanks. Rather, these generators produce their own never-ending supply of Nitrogen from the air we breathe. This will reduce the risk of running out of gas at inopportune times, giving your facility a steady stream of Nitrogen on-demand.

Call South-Tek Systems to learn more about our N2 GEN® equipment and how it can benefit your lab operation today: (888) 526-6284.

Use of N2 Gas in Medical and Pharmaceutical Industries

Nitrogen gas has a wide variety of uses across a range of multiple industries. From food storage to electronics manufacturing to corrosion prevention, Nitrogen can be used to keep products dry and sterile, improve their durability and even provide a safer, cleaner environment for industrial workers. Another common application for Nitrogen gas is within the medical and pharmaceutical industries. These industries utilize N2 gas to reduce the presence of oxygen in situations where combustion is a major concern. This is done through a process called blanketing.

Through blanketing, the environment is made inert so that the risk of fire and/or explosions is greatly reduced or eliminated altogether. Because oxygen is a key ingredient for combustion, eliminating the presence of oxygen by displacing it with N2 gas significantly improves the safety of the manufacturing facility.

In addition to reducing or eliminating the risk of combustion, blanketing with Nitrogen can also help preserve or improve the quality of the pharmaceuticals and other medical products. Blanketing with N2 gas essentially displaces the oxygen present with Nitrogen, so there is little to no chance of oxygen's harmful side effects. Corrosion, rust, oxidation and other significant reactions can occur when oxygen is present and reacts with other materials. This can seriously alter or damage the products being handled or manufactured. In the pharmaceutical and medical industries, it is imperative that conditions for the safe handling and manufacturing of products be preserved.

Here are a couple of specific examples of nitrogen uses in the medical and pharmaceutical industries:
  1. Nitrogen is often used in the packaging of medical supplies (Nitrogen helps maintain sterility and cleanliness of the product). Nitrogen is used to purge oxygen from the packaging before it is sealed, creating an environment made of high purity N2 gas, which will also help preserve and protect the product during transport. Test kits for doctors' offices, blood supplies, specimen containers and other medical devices are some examples of items frequently packaged with N2 gas.
  2. Nitrogen is often used in the transferring of pharmaceutical products. The use of a safe, inert gas to transfer liquid or powder pharmaceutical materials is necessary, as these materials can be hazardous if improperly handled.
Nitrogen Generators are systems that safely produce high purity Nitrogen gas and are often used for medical equipment in laboratories or hospitals.  Nitrogen Generators are safer and easier to handle than high-pressure cylinders. These generators can be used to control the level of oxygen in the workspace, lab or throughout an entire facility.

Nitrogen Generators are highly efficient, as they create their own supply of nitrogen from the surrounding air. With an onsite Nitrogen Generator from leading manufacturer South-Tek Systems, your facilities manager won't have to bother with changing out expensive, high-pressure cylinders. This not only improves the safety of your facility, it reduces costs and can help your lab operate at a higher level of efficiency.

For more information on how a Nitrogen Generator can benefit your medical or pharmaceutical facility, call South-Tek Systems at (888) 526-6284 or send your inquiry through our onsite contact form.

Food Storage with Nitrogen

Nitrogen can be used in manufacturing, industrial, commercial and retail applications, making it a pretty versatile gas. One of the many ways Nitrogen has benefited our lives is through its use in the food storage industry.

In the food storage and packaging industry, Nitrogen plays a critical role in preserving the product's freshness, flavor and texture.  N2 gas is a clean, dry and inert gas (which means it's very safe when handled properly) that can reduce or eliminate the presence of oxygen (which is an essential factor in the decay of organic matter).

With some exceptions, food and beverages that are purchased in grocery stores were likely packaged days or even weeks before they arrived on the shelves. In order to maintain the food's quality while in the packaging facility, and preserve its quality even after it's shipped, packaging facilities rely on optimized storing methods - which often include the use of Nitrogen gas.

Nitrogen displaces the presence of oxygen, but it can also be used in blanketing applications, which is a process in which the interior of the packaging is padded with Nitrogen gas to prevent crushed and broken food products like crackers, chips and other more fragile items.

Produce can also be effectively preserved by using nitrogen in packaging facilities. Nitrogen can help create an atmosphere in which levels of humidity and oxygen are controlled to decelerate the ripening process in fruits and vegetables. Apples, pears, bananas, tomatoes, and so on can have significantly different flavors and textures when they are overripe. By using Nitrogen to alter the atmospheric conditions in a food processing or storing plant, these items can have a much longer shelf life and, more importantly, they can maintain their good, fresh taste for consumers to enjoy.

One of the more common and most cost effective methods for introducing Nitrogen in such applications is to install a Nitrogen Generator from South-Tek Systems. Nitrogen Generators create high purity Nitrogen gas from the air we breathe, which means the supply will never run out and facility operators can free themselves from the tedious and hazardous task of storing high-pressure N2 gas storage tanks.

Biofuel Storage with Nitrogen

In recent years, the biofuel industry has seen tremendous growth. In 2011, Biofuels Digest reported a growing demand for alternative fuels, as evidenced by the results of the 2011 Bioenergy Business Outlook Survey. Not only did the survey reveal a growing demand for the biofuels market, it found that further growth is expected by 85 percent of industry executives (Source: Source: Biofuels industry increasingly bullish about 2011; cite "rising demand for alternative fuels" in Business Outlook Survey). Now more than ever, the need for safe, efficient biofuel storage is rising.

As the production of alternative fuels becomes more widespread, facilities that handle, transport and store these fuels will need to optimize their methods to ensure safety. Methanol, a key component of biofuel, can be extremely hazardous if improperly stored. When stored in tanks, for instance, methanol has a tendency to form flammable vapors. To ensure the safety of these storage tanks, Nitrogen is often utilized to prevent the formation of these vapors. By introducing Nitrogen into the extra space in methanol tanks, the presence of oxygen can be effectively eliminated. This process is known as atmosphere blanketing, or tank blanketing.

The process of tank blanketing using a dry, inert gas such as Nitrogen, can effectively reduce the risk of combustion, corrosion and other dangerous effects. Oxygen is an essential factor in combustion as well as oxidization, which can lead to corrosion. By eliminating the presence of oxygen, these problems are far less likely to occur.

While combustion is obviously a major safety concern, oxidization and corrosion can also cause negative effects. The presence of oxygen in biodiesel and methanol tanks can negatively affect the quality of the fuels. By practicing tank blanketing techniques, the quality of the biofuels can be preserved. Get more details on Biofuel Storage Tank Purging with Nitrogen Gas.

South-Tek Systems can further aid in a biofuel storage facility's operations by installing a Nitrogen Generator, which produces high purity Nitrogen from the surrounding air. Having an on-site Nitrogen Generator eliminates the need for purchasing, storing and handling high pressure nitrogen cylinders. This can be a cost effective alternative to having stored Nitrogen. With a Nitrogen Generator, facilities that rely on N2 gas for their essential operations can benefit from having a never-ending supply on demand while maintaining a safe, inert atmosphere for blanketing applications.

Exhaust Dilution with Nitrogen Gas

Exhaust dilution is an important process used extensively in manufacturing and industrial applications. The process works by emitting gas particles from mechanical engines and diluting phase pneumatic conveying of materials through a system of pipes.  This process cools the surrounding atmosphere and eliminates the presence of oxygen, alleviating a huge safety concern.

Without such a process in place, excess heat and dust can build up and oxygen can react with hazardous materials causing imbalances in pressure and even explosions. Additionally, the presence of oxygen can create unwanted damage through oxidization, a reaction that occurs when condensation forms along the mechanical equipment.

By using Nitrogen gas in an exhaust dilution process, the presence of oxygen can be eliminated, preventing oxidization and serious safety hazards. Because Nitrogen is a clean, dry and inert gas, it can help diffuse or dilute the materials found in a pneumatic conveying system without the unwanted presence of oxygen. Nitrogen is commonly used in pneumatic conveying systems to help transport materials, particularly closed-loop systems. In these systems, the gas is recycled and conserved as the transport medium.

Safety is a major concern when it comes to the operation of a pneumatic convey system. Some types of materials that are transported through these systems are explosive, especially in high concentrations. By using an inert gas such as Nitrogen, a pneumatic conveying system can function at the optimal level of safety. Through exhaust dilution with Nitrogen, these dangerous materials can be effectively transported and your facility and equipment can continue to operate successfully.

To learn more about Nitrogen for exhaust dilution, as well as other common industrial applications for Nitrogen, contact South-Tek Systems - a leading provider of Nitrogen Generators.

Other industrial applications for nitrogen include aerospace manufacturing, burst testing, nanolabs and there are many more. No matter what type of facility you run, it is likely that Nitrogen can help your business run more safely and efficiently. Call us at 888-526-6284 to learn more.

HVAC Manufacturing Using Nitrogen Gas

HVAC manufacturing involves processes that are sensitive to oxygen exposure - particularly the processes of brazing and leak testing.

Why Is Nitrogen Gas Important for HVAC Manufacturing?

Brazing is a heat treating method of joining two pieces of metal together by melting a metallic filler to form a strong and resilient bond while preserving the existing metal components.  Nitrogen is an important component during the brazing of copper coil for HVAC equipment.  Applying a steady stream of N2 gas during the brazing process prevents oxidation caused by exposure to oxygen.  Oxidation compromises the integrity of the bond and the metals, affecting the overall performance and life expectancy of the system.

Leak testing for refrigerant is a mandatory process for all HVAC systems with a charge of between 3 and 30kg (once a year) or more than 30kg (twice a year) and is regulated by the Environmental Protection Agency (EPA).  Nitrogen is the preferred gas for pressurized leak testing due to its inert nature and its ability to eliminate the presence of oxygen that can allow moisture to form that might cause oxidation and corrosion of the metal piping.

What is a Reliable and Economical Source for Continuous Nitrogen Gas Flow?

The need for Nitrogen gas for both brazing and leak testing during HVAC Manufacturing requires a steady, continuous flow without the possibility for running out during the session.  The best solution for this is to utilize a Nitrogen Generator that produces high purity N2 gas by separating the Nitrogen molecules from the atmosphere and storing them in an attached tank.  Nitrogen gas is available on demand, directly at the point of process.

South-Tek Systems is a leading manufacturer of Nitrogen Generating equipment, including the N2 GEN Series for industrial applications such as HVAC Manufacturing, brazing, and pressure leak testing.  Contact the experts at South-Tek today to learn how their Nitrogen Generators can benefit your operation: 888-526-6284.
