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
Technical Specifications:

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.
