The Nitrogen generator produces Nitrogen gas from atmospheric air using Molecular Sieves Separation technique. It uses Carbon Molecular Sieves which has ability to preferentially remove oxygen from air. Our proprietary technique get higher efficiency of gas separation.
Nitrogen generator consists of two beds filled with Carbon Molecular Sieves. When compressed air is passed, Nitrogen comes out as product gas from one bed while other bed is simultaneously regenerated by depressurization to atmospheric pressure. This process of gas separation is called “Pressure Swing Adsorption” (PSA).
From Nitrogen generator gas of purities from 99% to 99.99995 can be produced. Simple PSA Unit produces raw Nitrogen of 99% purity. By adding purification unit to PSA unit, high purity nitrogen can be produced.
Nitrogen generator are tailor made equipment and are manufactured as per customer’s requirements. However, standard units are available in the capacity of 1, 2, 5, 10, 25, 50, 75, 100, 150, 200, 300 Nm3/hr. the gas generators can be manufactured in any desired capacity.

A PSA nitrogen generator is a device that produces high-purity nitrogen gas by separating nitrogen molecules from compressed air using a process called Pressure Swing Adsorption (PSA).
PSA nitrogen generators operate on the principle of selective adsorption. Compressed air is passed through a vessel containing an adsorbent material (such as carbon molecular sieve or zeolite) that selectively adsorbs oxygen molecules while allowing nitrogen molecules to pass through. The adsorbed oxygen is then released when the pressure is reduced, leaving behind high-purity nitrogen gas.
PSA nitrogen generators can produce nitrogen with purities ranging from 99% to 99.9999%, depending on the specific application requirements.
Factors to consider when selecting a PSA nitrogen generator include the required flow rate, purity level, operating pressure, ambient conditions, and specific application requirements. Consulting with a nitrogen generation expert can help determine the most suitable system for your needs.
Routine maintenance typically includes replacing filters, checking and replenishing adsorbent material as needed, and ensuring proper operation of valves and controls. Maintenance schedules may vary depending on usage and environmental conditions.
Yes, PSA nitrogen generators can often be integrated into existing compressed air systems with proper planning and installation. Retrofitting options are available to accommodate various setups and configurations.
