Pressure Swing Adsorption Medical Oxygen Generator High Purity for Welding

PSA oxygen generator

PSA ( Pressure Swing Adsorption) Technology a revolution in Non Cryogenic Air Separation and

Oxygen Generation Technology uses special grade of ZMS ( Zeolite Molecular Sieve).

The compressed air is passed through a Twin Tower PSA module interconnected with automatic

changeover valves. After passing through a Refrigerated Dryer air gets dried. Dried compressed air

will now come in contact with bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are special

grade of adsorbent which have the property of preferential adsorption of nitrogen molecules.

At a time one tower remains under nitrogen production cycle, whereas the other tower undergoes

regeneration

which is achieved through depressurization of the tower to atmospheric pressure. The outgoing oxygen

gas is sent to a surge vessel where the minimum pressure will be maintained with the help of Back

pressure Regulator

Application :

1. After the oxygen generator, the oxygen purification system is equipped to guarantee the quality

of the O2 and removing dust, eliminating bacteria and stabilizing pressure to ensure the oxygen

outputted stably and meeting medical standards.
2. Users only need to turn the start/stop button to gain the oxygen with designing required flow capacity

and purity within 30 minutes.

3. Single line and double lines types are available for option. Users are suggested to choose the single

line type when they only require a stable flow capacity; choose double lines when demand is unstable

and sometimes meet extra peak values.
