Description

Perfect Medical Solution on-site PSA oxygen plants are based on the well-known PSA technology.
(PSA means pressure swing adsorption). Two pressurised vessels with zeolite ensure continuous production for separation of oxygen from other gases.

An PSA Oxygen Plant O2 generator consists of two pressure vessels storing zeolite.

Dry compressed air is blown through a valve to the first vessel where the pressure is built to reach 4 to 8 bar(g). The unwanted gas (N2) is adsorbed by the zeolite during the building of pressure, and the oxygen will pass through to the accumulation tank.

While pressure is building in one vessel, the other vessel is regenerating through a decrease in pressure. This process guarantees a continuous flow. Before the subsequent adsorption or desorption stage, the pressure between the adsorption vessels will be equalised. When pressure decreases in the first vessel, and the zeolite becomes saturated, the waste product is exhausted through the exhaust system. Now the pressure in the second vessel will build up until the pressure between both vessels is once again equalised
