N2 GEN Portable Nitrogen Generator from South-Tek Systems Completes Military EMIP Review


South-Tek Systems N2 GEN portable Nitrogen Generator series successfully completed a review by the military-based Expedited Modernization Initiative Procedure (EMIP).

Wilmington, N.C., December 28, 2009 -- South-Tek Systems, designer and manufacturer of Nitrogen Generators, has successfully completed a review of its N2 GEN series of portable Nitrogen Generation systems by the military based Expedited Modernization Initiative Procedure (EMIP).  Only a dozen technologies a year are chosen to go through the EMIP review process, which involves an extensive application and submission method for each technology.

The N2 GEN Series Nitrogen Generator gives U.S. warfighters the capability of producing inert Nitrogen gas, an element critical to maintenance in the field or at the maintenance facility.  The N2 GEN eliminates the safety and logistical issues involved with transporting high pressure gas cylinders.

According to the official EMIP website, "The Expedited Modernization Initiative Procedure (EMIP) is a multi-phased and continuous market research process" conducted by the U.S. Military with the goal of educating Government representatives about new technologies for vehicles and fleets.  "EMIP is primarily designed to suggest improvements to the current and future fleet of tactical wheeled vehicles and other systems. EMIP seeks to identify an industry's investments in proven, advanced, commercial technologies at the component, and subsystem levels, at a Technology Readiness Level (TRL) 7, or better."

TRL 7 readiness level requires demonstration of an actual system prototype in an operational environment such as a vehicle, aircraft, or space. 

EMIP seeks technologies that will improve the capabilities of current and future military vehicles and places emphasis on technologies that address solutions in warfighting capabilities that include safety, survivability, reliability/maintainability/sustainability (RMS), distribution/mission enhancements (DME), and mobility.

For the past four years, the N2 GEN portable Nitrogen Generator from South-Tek Systems has been incorporated into Humvee mounted optical labs and mobile maintenance trailers.  It has been deployed in combat venues in both Iraq and Afghanistan.

In particular, the N2 GEN supports safety capabilities that are sought through the EMIP process, reducing non-combat casualties by eliminating the need for transporting high pressure cylinders of compressed Nitrogen gas to maintenance sites.  The RMS capabilities of the N2 GEN reduce operator maintenance tasks by reducing paperwork and eliminating the need to transport gas cylinders or arms to and from maintenance depots and sites.

"Providing Nitrogen in the field of active duty is a particularly complicated problem because compressed Nitrogen is not readily available," says Charles Metzler of South-Tek's Military/Industrial Division.  "We feel that completing this review process will help South-Tek Systems bring the N2 GEN to the attention of those who need it the most."

Fuel Tank Safety Using Nitrogen Generators

Fuel tanks are closed or sealed pressure vessels carrying highly flammable gases for the purposes of providing fuel to a source such as an aircraft.  Such fuel tanks run a high risk of fire or explosion when the following three factors are in play:
  1. Heat as an ignition source,
  2. Fuel as the contents of the vessel, and
  3. Oxygen to initiate and sustain the fire
Eliminating one of these three factors prevents the potential for fire or explosion.  Since a fuel tank carries fuel - one of the three vital factors - that one cannot be eliminated.  If it is not possible to eliminate the heat or ignition source, then it is necessary to eliminate or significantly reduce the presence of Oxygen in the tank.

The process of reducing Oxygen from the fuel tank is called inerting.  One way to accomplish an inert atmosphere is to pump Nitrogen gas into the tank in order to displace the Oxygen and reduce its content to a level below the threshold required for combustion.  Nitrogen is a cool, dry, inert gas that acts as a safe replacement for Oxygen within a pressure vessel such as a fuel tank.

A Nitrogen Generator provides a great advantage when used for inerting fuel tanks.  N2 Generators supply a steady stream of Nitrogen gas on-demand and on-site in a safe and reliable system.  In comparison to a high pressure Nitrogen gas cylinder, there are a number of advantages including:
  • increased safety, 
  • increased reliability, 
  • decreased costs over time,
  • decreased dependency on gas company deliveries,
  • increased savings on Nitrogen gas that is otherwise lost to evaporation during delivery and storage in high pressure cylinders
  • increased self sufficiency when gas company contracts can be eliminated and N2 gas generated on-site.
South-Tek Systems specializes in designing and manufacturing Nitrogen Generators used in a wide range of applications, including fuel tank inerting.  South-Tek employs a Flow Verification Program to ensure that each client is appropriately suited with the most efficient Nitrogen Generator for their particular application.

Heat Treating Safety with A Nitrogen Generator

Heat treatment of metals requires the presence of N2 gas for both safety during the process of treatment and quality of the final product.  Nitrogen is used to quickly cool a metal that has been heated to extreme temperatures in order to alter its properties, often for conditioning and hardening.  It is also used for blanketing purposes in order to provide a safe and neutral atmosphere for treatment.

See more information about Heat Treating with Nitrogen Gas.

Metals and alloys are heat treated to enhance their strength and build up their resistance to wear and corrosion.  Metals can also be tempered to increase flexibility or to relax stresses.  Heat treatment application results in high quality parts that can be supplied at competitive prices, especially when Nitrogen gas is generated on-site for blanketing purposes to reduce oxidation and absorb hydrogen.

A Nitrogen Generator from South-Tek Systems is effective at producing high purity N2 gas on demand using a simple and reliable process.  The use of a Nitrogen Generator in heat treatment of metals streamlines the process, making it more safe, reliable, and cost-effective.

There are a number of techniques that can be applied to heat treating metals using Nitrogen gas as a blanketing agent for both safety and quality concerns and/or a forced air cooling agent for heated metals.
  • Quenching
  • Tempering
  • Annealing
  • Hardening
  • Galvanising
  • Normalising
  • Sintering
