PSA Nitrogen Generator, Twin Tower Systems

GENERON® Nitrogen PSA Generators separate nitrogen from compressed air utilizing Pressure Swing Adsorption (PSA) technologies.  Compressed air, which consists of approximately 21% oxygen and 78% nitrogen, is passed through a bed of Carbon Molecular Sieve (CMS).  The CMS preferentially adsorbs O2 and moisture, allowing the N2 to pass through as a product gas at the specified pressure.  While one of the towers is in the adsorption phase, the other tower is being regenerated, by de-pressurizing and allowing the CMS to release the adsorbed gases to the atmosphere.  The cycle then repeats, allowing for constant flow of a controlled Nitrogen purity and flow.

This product line is designed for medium to large flow rates and has a reduced footprint. It consists of single pairs of our Twin Tower Adsorber Vessels and air and nitrogen buffer vessels (installed on a common skid or supplied separately).
