Gas Generators

We design and develop a stellar range of gas generators such as PSA nitrogen gas generators, oxygen gas generators, & hydrogen gas generators. These gas generators are designed to operate on low-cost fuel sources. Our range of gas generators are built to the highest standards of performance.

The PSA nitrogen gas generators offered by us produces nitrogen gas from atmospheric air using molecular sieves separation techniques. The carbon molecular sieves, which has the ability to preferentially remove oxygen from air is used in this generators. The molecular sieves process and supply used by us is licensed by Carbotech Industrieservice- Germany.

The nitrogen generator comprises of 2-Beds filled with carbon molecular sieves. The nitrogen comes out from one bed as a product gas when compressed air is passed. The other bed simultaneously regenerated by de-pressurization to atmospheric pressure. The entire process is known as "Pressure Swing Adsorption" (PSA).

Nitrogen Purity
From our range of nitrogen gas generator we can produce gas of 99% to 99.9999% purities. Simple PSA unit produce raw nitrogen of 99% purity. When purification unit is added to PSA unit, high purity nitrogen is produced.

Nitrogen Gas Generator Models
There are different nitrogen gas generator models to produce various Nitrogen purities. They are as follows :

MS-Model : It is the simplest model, which produce commercial grade 99% purity nitrogen economically. When the carbon molecular sieves quantity is increased, 99.999% purity nitrogen can also be produced from this model. To get this highly pure nitrogen, the investment and running cost will be higher. This economical model is recommended for purity upto 99.9% and is commonly used for purging/inertizing applications.

DX-Model : This model is recommended for use in metallurgical industries to provide oxygen free nitrogen gas for heat treatment furnaces. In this generator the oxygen is less than 1-ppm and Hydrogen is around 0.5 to 1% . It is desirable as a reducing constituent in, most heat treatment applications.

When palladium catalyst based deoxo purification module is added in "MODEL-MS" Generator, it becomes "DX-MODEL" . This DX model is mostly used in Chemical/Metallurgical/Heat Treatment Industries.

Copper-DX Model : Copper DX model nitrogen gas generators offers very very pure gas, which is free from any oxygen and hydrogen. The nitrogen purification module is based on copper deoxo catalyst, which is added over here. By adding copper catalyst module to the existing "MS Model" Generator, it becomes Model "Copper- DX" generators. It is used in synthetic fiber, optical cables and electronic industries. Cost of production of nitrogen from this Copper-DX model is higher than others.

Advantages of Nitrogen Gas Generator :-

• Automatic & start-up time is 5-Minutes.
• The nitrogen gas supplied is always under your control.
• For easy site installation it has a self-contained skid mounted units.
• Low maintenance costs.
• High reliability with low maintenance.
• Carbon Molecular Sieves life is around 15-years and in most cases it lasts the whole life time of Gas Generator, never requiring replacement.
