High Purity Self Generating Nitrogen Service Cart

(HP-SGNSC)

Electric Driven
P/N: 130010-100
NSN: 3655-01-621-3781

High Pressure Purity Nitrogen Carts

This Nitrogen Servicing Cart is a self-contained, enclosed, skid mount, electric driven designed to produce gaseous Nitrogen at a flow of 30 Standard Cubic Feet per Minute (SCFM), at purity of 99.5% or better, and a pressure of 5,000 Pounds per Square Inch Gauge (psig) to the flight line and the maintenance shops to support multiple airframes. The nitrogen servicing cart can be used to perform the following functions:
• The low pressure side of the nitrogen cart provides a source of Nitrogen at controlled pressures of 0-400 PSI to service aircraft tires or other components.
• The high pressure side of the nitrogen cart provides a source of Nitrogen at controlled pressures of 0-5000 PSI to service aircraft high pressure nitrogen system and components.
• Fill up on-board storage bottles with 5,000 PSIG pure 99.5% Nitrogen or better in less than 45 minutes at ambient
temperature.

*
Features:
• Automated PLC controlled Nitrogen generation and filling with minimum operator interaction limited to “ON” and “OFF” operation.
• Sophisticated automatic and continuous Nitrogen purity control and calibration with on-board purity analyzer
• Full operation and maintenance diagnostic via Human Machine Interface (HMI) touch screen with fault logs and
troubleshooting aid.
• Unlike any other Nitrogen generators in the market, HII 100% Oil-less feed and high pressure air compressors
eliminate the need for oil separators, as a result extending the life of the Nitrogen separation membranes, eliminating oil filter change, maintenance resulting in reduction of the overall life cycle cost of the HPSGNSC.

High Purity Nitrogen Applications

• Aerospace & Motor Industries for charging of tires, aircraft accumulators, struts etc.
• In Food and beverage industries, nitrogen is applied to flood the products with Nitrogen that takes out the oxygen and prolongs the product lifetime and freshness significantly because these organisms cannot develop. Furthermore, chemical degradation of food caused by oxidation can be eliminated or stopped.
• Analytical chemistry for Liquid chromatography–mass spectrometry and Gas Chromatography where a stable inert and continuous supply of Nitrogen is necessary.
• Chemical and petrochemical industries for the provision of inert environment aimed at ensuring general industrial safety during cleaning and protection of process vessels. Nitrogen is also used for pipelines pressure testing, chemical agents transportation, and regeneration of used catalysts in technological processes.
• Electronics industry, in which Nitrogen serves as an antioxidant in the manufacturing of semi-conductors and electric circuits, heat treatment of finished products, as well as in blowing and cleaning.
• Glass industry, where nitrogen proves efficient and cost effective way as a cooling agent for bow oven electrodes, oxidation inhibitor during process procedures, as well as air cooler.
• Metallurgy utilizes nitrogen as a method of protecting ferrous and non-ferrous metals during annealing. Besides, nitrogen is very helpful in such standard industry processes as neutral tempering, cementing, hard brazing, stress relieving, cyanide hardening, metal-powder sintering and extrusion die cooling.
• Paint-and-varnish industry uses nitrogen for the creation of an inert environment in process vessels to ensure safety, as well as for oxygen displacement during packing in order to prevent polymerization of drying oils.
• Petroleum industry, where nitrogen is used to create an inert environment for preventing explosions and for improving fire safety, to support transportation and transfer of hydrocarbons. Furthermore, nitrogen is used for pipelines testing and purging, cleaning technological vessels and cleaning liquefied gas carriers and hydrocarbon storage facilities.
• Pharmaceutical industry, where nitrogen finds many applications in pharmaceuticals packaging, to ensuring against explosion, improving fire safety in activities where fine dispersed substances are used.
• Hypoxic air fire prevention system to produce air with a low oxygen and high nitrogen content.
