PSA Oxygen Generator

Oxygen PSA Generators separates oxygen (O2) from compressed air utilizing pressure swing adsorption technology. Compressed air, which consists of approximately 21% oxygen and 78% nitrogen, is passed through a bed of zeolite molecular sieve (ZMS). The sieve preferentially adsorbs N2 and moisture over O2 allowing the O2 to pass through as a product gas at pressure. While one of the towers is in the adsorption phase the other tower is regenerated by de-pressurizing, at which time the sieve releases the adsorbed gases to the atmosphere, and the cycle is then repeated. A solid state programmable controller operates the process valves on an alternating cycle, with built-in logic for automatic stop/start. Oxygen flow and purity remain constant regardless of the peak usage demands. Under normal operating conditions and with correct maintenance the zeolite molecular sieve will have an almost indefinite lifetime.
The Zeolite material have a very unique property that when the pressure is released back to atmospheric pressure during the regeneration process the Zeolite releases the Nitrogen that was stored on its surface. The process consists of switching the compressed air from one vessel to the other by means of a series of valves in a very precise sequence to take advantage of this unique property.

This process provides a constant flow of Oxygen for a multitude of applications.
