90%-94% High Purity Medical Oxygen Generator Fully Automatic for Metal Cutting

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

Product Features
·

1).Full Automation

All systems are designed for un-attended operation and automatic Oxygen demand adjustment.

2).Lower Space Requirement

The design and Instrument makes the plant size very compact,assembly on skids,prefabricated from

factory.

3).Fast Start-up

Start up time is only 5 minutes to get desired Oxygen purity.So these units can be switched ON&OFF

as per Oxygen demand changes.

4).High Reliability

Very reliable for continuous and steady operation with constant Oxygen purity.Plant availability time is

better than 99% always.

5).Molecular Sieves life

Expected Molecular sieves life is around 15 years i.e. whole life time of Oxygen plant.So no replacement

costs.

6).Adjustable

By altering flow,you can deliver nitrogen with precisely the right purity.

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.
