Descreption of large oxygen generator
ETR PSA Medical Oxygen Plant can fill medical level oxygen into cylinders, as a complete system, large oxygen generator is widely used for the oxygen gas station and hospitals.
Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The generator produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%-95% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4 bar pressure, and with a oxygen booster, the delivery pressure can up to 150 bar.and then fill in cylinders with an oxygen cylinder filling station.

| ETS- B40 | 40 | 160 | ||
| ETS- B50 | 50 | 200 | ||
| ETS- B60 | 60 | 240 | ||
Note: Filling capacity based on 15Mpa pressures &40L cylinder volume &24 operation hours per day | ||||
— Working Principles —
The medical molecular sieve PSA Oxygen Generator For Cylinder Filling system applies the international advanced pressure swing adsorption (PSA) technology to form a rapid cycle of pressurization adsorption and depressurization desorption under the conditions of normal temperature and low pressure.
