Specification :
â Air-Tech Engineersâ , is a leading manufacturer, supplier, and exporter of world class quality Nitrogen Gas Generators in India. Our world class Nitrogen Gas Generator works on Pressure Swing Adsorption ( PSA) technology, which separates nitrogen and oxygen molecules from rich compressed air. Commercial nitrogen production process usually employ carbon molecular sieves as adsorbents. In Pressure Swing Adsorption ( PSA) technology, the oxygen is adsorbed to its equilibrium value much faster than nitrogen because oxygen molecules which is smaller in size ( kinetic diameter 3.46 A.o) diffuses much faster in carbon molecular sieves than nitrogen ( kinetic diameter 3.64 A.o) . Air-Techâ s Nitrogen Gas Generators are custom made and can be adjusted to give the desired nitrogen purity for your process and application. Air-Techâ s Nitrogen Gas Generator produces Nitrogen purity in the range of 98% to 99.9999% can be achieved through our various models of nitrogen gas generators stated below.
Nitrogen Gas Generator Model - ATLP :
This is the basic and simplest model of Nitrogen Gas Generator, Which produces commercial grade Nitrogen from 98.0% to 99.5 % purity.
Gas Composition Model ATLP
Nitrogen From 98 to 99.5%
Oxygen 0.5%
Hydrogen Nil
Dew Point ( -) 40 Deg.C to ( -) 80 Deg.C
Application of Nitrogen Gas Generator:
v Storage against Oxygen and Moisture.
v Packing against Oxidation Contamination in Food, Dairy, Pharmaceutical.
Nitrogen Gas Generator Model - ATHP :
This is High Purity Nitrogen Gas Generator, Which produces commercial grade Nitrogen upto from 99.0% to 99.9 % purity.
Gas Composition Model ATHP
Nitrogen From 99.0% to 99.9%
Oxygen Upto 0.1%
Hydrogen Nil
Dew Point ( -) 40 Deg.C to ( -) 80 Deg.C
Application of Nitrogen Gas Generator:
v Blanketing in Process Plant, Chemical & Petro-Chemical Industries.
v Storage against Oxygen and Moisture.
v Pressure transfer of sensitive Chemicals.
v Packing against Oxidation Contamination in Food, Dairy, Pharmaceutical.
v Fire Control in Coal Mines.
v POY / PFY process.
Nitrogen Gas Generator Model - ATUHP :
This is Ultra High Purity Nitrogen Gas Generator, which is capable to produce Nitrogen Gas upto 99.999% purity. Always higher the purity, higher would be the investment and higher would be its running cost. These models are recommended where very high purity nitrogen gas is require. Here, Nitrogen and Hydrogen ( from Ammonia Cracker or from Hydrogen Bottle) is mixed and is passed through a Palladium based Deoxo unit where the below specified reaction takes place :
O2 + 2H2 = > 2H2O + Heat
After above reaction the product Gas would be with higher temperature which is cooled down in a Heat Exchanger and simultaneously, its moisture is removed by the Gas Dryer. The Gas Composition of this model comprises 1 to 3 ppm of Oxygen content and 0.5 to 5.0 % Hydrogen which is desirable as reducing agent in most of the Heat Treatment Application. Atmosphere of desired composition and character is made by selective addition of Hydrogen / Hydro-Carbon, Methanol to Nitrogen as appropriate to specific heat treatment process and metals to be treated.
Gas Composition Model ATUHP
Nitrogen From 99.0% to 99.999%
Oxygen Upto 1-3 ppm
Hydrogen 0.5%
Dew Point ( -) 60 Deg.C to ( -) 80 Deg.C
Application of Nitrogen Gas Generator:
v Heat Treatment Application to avoid Oxidation in Metallurgical Industries
v Nitrogen Based Control Furnace whose atmospheres in heat treatment process like Annealing, Normalizing, Carburizing, Hardening etc. of metals.
Nitrogen Gas Generator Model - ATSUHP :
This is Super Ultra High Purity Nitrogen Gas Generator, which is capable to produce Nitrogen Gas upto 99.9999% purity. Always higher the purity, higher would be the investment and higher would be its running cost. These models are recommended where very high purity nitrogen gas is require. This model is suitable for Oxygen free Nitrogen. The product Gas comprises 1 ppm Oxygen and Zero Hydrogen ( or adjustable as desired) . This Composition is achieved by adding a module called Copper-Deoxo consisting of Cupric Oxide. The following would be the chemical reaction :
02 + 2Cu --------------> 2CuO
After above reaction the product Gas would be with higher temperature which is cooled down in a Heat Exchanger and simultaneously its moisture is removed by the Gas Dryer.
Gas Composition Model ATSUHP
Nitrogen From 99.0% to 99.9999%
Oxygen Upto 1 ppm
Hydrogen Nil
Dew Point ( -) 60 Deg.C to ( -) 80 Deg.C
Application of Nitrogen Gas Generator:
v Semi-Conductor application
v Electronics etc.
Salient Features of Nitrogen Gas Generator:
v The Nitrogen Gas Generator is Skid mounted and Pre-commissioned at our works.
v These are fully automatic and require no attention of the Operator.
v All operations takes place automatically and Nitrogen Purity remains very consistent.
v In case of any abnormality the gas Generator would trip automatically with Audio Visual Alarms for Necessary action.
v Customized design to meet your process requirements.
v Minimal space requirement.
v Your own independent on-demand Nitrogen Gas.
v Environment Friendly.
