Industrial Medical PSA Oxygen Generator System , CE / ISO / Approved
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
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 un-attended operation and automatic Oxygen demand adjustment.
2. Lower Space Requirement
The design and Instrumentation makes the plant size very compact, assembly on skids, prefabricated and
supplied from factory.
3. Fast Start-up
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 life time of 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 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.
