PSA Oxygen Generator System, Industrial, and Hospital, Application, CE / ISO / Approved

PSA oxygen generator 

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

Oxygen Generation Technology uses a 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 the bed of Zeolite molecular sieves (ZMS). Zeolite Molecular Sieves are a special 

grade of adsorbent that has the property of preferential adsorption of nitrogen molecules. At a time 

one tower remains under the 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 a Backpressure Regulator

 Principle:

The traditional methods of making oxygen need to cool air into liquid, via exacting to get oxygen. PSA oxygen generator under normal temperature, and normal pressure working, had the following advantages:

 Lower cost, PSA oxygen system choosing special ZMS CMS and advanced technical design make the plant lower investments, lower consumption, compared to another oxygen system little maintenance, etc characteristics.

 Simply flow sheet, automatic level, operation easily.

 Compared to air separation, which needs a small area, a perfect constructor, safe area, it can be used both outdoors and indoors.

 Operate quickly, Oxygen can be supplied within 5 minutes, shut convenient, can operate easily, the system will control automatically fully, no need for workers on duty.

 Working under normal temperatures, and lower pressure, the whole recovering process does no need heating, it is safe.

 The oxygen purity and capacity can adjust easily, strong adaption, oxygen purity (30%-93%), and purity can control, while the oxygen capacity or purity down can greatly save energy.

 Super filter protective system reduces the pollution for ZMS CMS, advanced molecular sieves compressed technology reduces sieves pulverization, and bed down reduce function.

Technical Specifications:

Capacity: 2~150 Nm3/h

Purity: 92±2%

Initial Pressure: 0.05~0.4 Mpa

Dew point: -65℃

Product Features

 1.  Full Automation

      All systems are designed for unattended operation and automatic Oxygen demand adjustment.

 2.  Lower Space Requirement

The design and Instrumentation make the plant size very compact, assembly on skids, prefabricated and

 supplied from the factory.         

 3.  Fast Start-up

The start-up time is about 30 minutes to get desired Oxygen purity. So these units can be switched ON & OFF

 as per Oxygen demand changes.

 4.  High Reliability

It's very reliable for continuous and steady operation with constant Oxygen purity. Plant availability 

time is better than 93% always.

 5.  Zeolite Molecular Sieves Life

Expected Zeolite Molecular Sieves life is more than 10 years i.e. whole lifetime of the Oxygen plant. 

So no replacement costs.

 6.  Low investment and energy consumption

 7.  Simple operation and maintenance

Application :

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

of the O2 and remove dust, eliminate bacteria, and stabilize pressure to ensure the oxygen 

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

and purity within 30 minutes.          
                                                      
3. Single line and double line 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.
