PSA & VPSA OXYGEN GAS GENERATORS
Standalone Twin Tower PSA Oxygen Gas Generator (STT Oxygen Series)
Designed to replace an existing gas generator in a facility or suitable where a customer already has excess dry compressed air available with a suitably sized air receiver & oxygen storage tanks to go with it.
Easy start-up at the site with minimal expertise.
Custom-designed to meet your process flow rate requirements and pressures up to 5 Barg or 72.5 Psig.
Suitable to generate oxygen gas purity up to 96 %.
Field Expandable Standalone PSA Oxygen Gas Generator (FES Oxygen Series)
Designed to replace an existing gas generator in a plant or suitable where a customer already has excess dry compressed air available with a suitably sized air receiver & oxygen storage tanks to go with it.
FES system grows with your operation & flow output of the system can be increased by adding additional towers in the future instead of investing again in a whole new gas generator as long as the system can be supplied with required excess dry compressed air. Allows easy expansion at the site.
Easy start-up at the site with minimal expertise.
Custom-designed to meet your process flow rate requirements and pressures up to 5 Barg or 72.5 Psig.
Suitable to generate oxygen gas purity up to 96 %.
Twin Tower VPSA Oxygen Gas Generator
VPSA oxygen gas generator is designed for large-scale applications where oxygen flowrate requirements exceed a minimum of 200 Nm3/hr or 120 Scfm.
Oxygen gas delivery pressure range 3-5 Psig.

How a PSA Oxygen Gas Generator Works
Working Principle
The air that we breathe on earth is made up of 78 % nitrogen and 21 % oxygen. Air also has other inert gases in very small quantities.
The pressure swing adsorption(PSA) process is designed around two or more adsorber towers which are filled with zeolite molecular sieve(ZMS) material. An Air compressor is used to supply compressed air which is further treated with a refrigerated dryer to reduce the air dewpoint to +3 to +5 Deg C & set of filtration to make compressed air completely free of any heavy particulate & oil contaminations. Dry & oil-free air then enters the adsorber tower where zeolite molecular sieve material has a strong affinity for nitrogen & water molecules therefore these molecules get adsorbed to the ZMS porous surface under pressure and pure oxygen gas is collected & stored in a storage tank at the outlet. when one tower is under adsorption, another tower is regenerated by reducing the tower pressure close to atmospheric pressure to release the adsorbed gases and allowing a small amount of pure oxygen gas as purging gas to remove any nitrogen & water vapor impurities, the cycle repeats itself to produce oxygen gas continuously.
How a VPSA Oxygen Gas Generator Works
Working Principle
In a VPSA oxygen gas generator, the air is supplied to adsorber towers by a low-pressure blower instead of an air compressor. separation of oxygen from the tower takes place exactly as in a standard PSA system with the exception that the towers are regenerated by applying the vacuum to zeolite molecular sieve material.
