PSA Principle

        PSA technique (Pressure Swing Adsorption, PSA for short):it's a kind of advanced gas separation technology, based on physical adsorption of gas molecule on the internal surface of adsorbent (porous solid substances), using adsorbents in the same pressure easy to absorb the high boiling point gas, difficult to absorb low boiling point gas, and under high pressure adsorption amount of absorbed gas increases, under low pressure adsorption of absorbed gas to reduce the features to achieve gas separation.

        This process under pressure adsorption of impurities, under reduced pressure desorption of impurities, make the adsorbent regeneration, is the PSA cycle.

Features

1. Specific pressure protection measures of  molecular sieve, molecular sieve is difficult of pulverization, long service life;

2. Low energy consumption, the product of high oxygen purity;

3. Reasonable internal components, air distribution uniformity, reduce air high-speed impact;

4. The whole equipment of a high degree of automation.;

5. Multifunctional monitoring system, realize gas, purity, pressure LCD online display, equipment failure warning, maintenance tips, fully grasp equipment running states;

6. Can be fully integrated skid mounted design, easy installation and rapid deb ing;

7. Optional oxygen flow, remote monitoring system, etc.
