Nitrogen Gas Company South-Tek Systems Hires New Engineer Patrick Sigmon

South-Tek Systems, a leading nitrogen gas company, welcomes mechanical engineer Patrick Sigmon to its engineering department.  Mr. Sigmon has a focus on CAD Drawing and Design work and the South-Tek team is excited to have him join with them full time in June 2012.

Wilmington, N.C., May 2012 -- South-Tek Systems is excited to welcome new mechanical engineer Patrick Sigmon to their Engineering Department. This leading Nitrogen Gas company engineers and manufactures nitrogen generating systems for use with a wide variety of applications across many industries worldwide. Mr. Sigmon represents the most recent hire during an expansion of the South-Tek Systems Engineering Team over the last year.

The Engineering Department at South-Tek Systems is the driving force behind the design and functionality of every Nitrogen Generating System developed at the company. Products range from compact and portable N2 generators to high pressure systems. Each model fulfills a specific pressure and purity requirement for use with applications including electronics manufacturing, food packaging, power plants, military uses, and more. The engineers at South-Tek Systems also work to develop products aimed at particular markets. Some of these products include the N2Blast® Corrosion Inhibiting System for Fire Protection Systems, the BeerBlast® Mixed Gas Dispense System, and the TireBlast® Nitrogen Tire Inflation System

Mr. Sigmon joins the South-Tek Systems Engineering Department with a Mechanical Engineering Technology degree from Cape Fear Community College and an emphasis on Computer Aided Design (CAD) Drawing. He has previous corporate experience performing CAD work in an engineering firm based in Wilmington, N.C. The opportunity to join with South-Tek Systems, a growing international company, upon obtaining his degree is exciting for Mr. Sigmon. The company looks forward to seeing his talents applied to their design and engineering projects.

South-Tek Systems designs and installs Nitrogen Generators for companies and industries of all sizes, from food packaging and wine making, to power plants and military field operations. Their N2 gas generating systems and extensive experience has them working them around the world, most recently at an Iraqi Government-owned oil company in Basra. South-Tek Systems completed a PSA Nitrogen Generator industrial installation at the South Refinery Company in Basra as part of a modernization project for the refinery and as part of a larger attempt at moving toward economic self-sufficiency for the country. South-Tek is also a GSA contract holder, providing approved products and services to federal employees, military officials, and agencies worldwide.

As South-Tek Systems continues its growth and expansion, their engineers are hard at work delivering Nitrogen Gas generating systems as well as advanced monitoring and management systems for quality control and regulation. Patrick Sigmon will be a welcome addition to the South-Tek team.

Controlled Atmosphere Storage for Fruits and Vegetables

The storage of fruits and vegetables, and particularly produce such as apples and pears, can be optimized with the use of Controlled Atmosphere Storage.  This process works by maintaining specific settings for elements including temperature, oxygen, carbon dioxide, and humidity.  The controlled atmosphere allows produce to remain fresh and crisp longer because the ripening process is significantly slowed.

Fruits and vegetables that "breathe" ripen through the process of taking in oxygen and giving off carbon dioxide.  By controlling how much oxygen and carbon dioxide circulates throughout the storage room, the ripening process can be altered to ensure that fruits are still fresh by the time they reach their destination.  We've written about this slowed ripening process in a previous blog post here: Controlled Atmosphere Storage Using Nitrogen

Using Nitrogen for Controlled Atmosphere Storage

Nitrogen gas is used to control the atmosphere of the storage room because it is an inert gas that can displace and reduce the presence of oxygen which also decreases the humidity level.  Limiting oxygen and humidity using nitrogen gas will help slow the fruit's ripening process and preserve freshness for a longer period of time.

Nitrogen generating systems installed at the point of process for Controlled Atmosphere Storage are a safe and reliable alternative to liquid N2 gas stored in high pressure cylinders.  South-Tek Systems is a leading manufacturer of Nitrogen Generators used in a wide variety of applications, including food packaging, modified atmosphere packaging, and controlled atmosphere storage.
