Medical Oxygen Generators
Pressure Swing Adsorption Technology
 

Pressure Swing Adsorption (PSA) technology is used with specially developed adsorbents called Carbon Molecular Sieve (CMS) to separate nitrogen from air to be able to use pure nitrogen in many applications.

First, air is compressed up to 10 bars with the help of compressors, then air is dried out to remove the moisture in the air either using refrigerant dryers or desiccant dryers. Filtration takes place thereafter to filter out the remaining particles, aerosol and oil which is in the pressurized air stream. Carbon Tower ensures long term oil free nitrogen delivery.

PSA unit consists two tanks filled with CMS. Each column undergoes cyclic sequence of pressurization, generation, equalization and exhaust cycles for continuous flow of high purity nitrogen.

 

PSA Advantages
 

Reduction of nitrogen cost
Safe low-pressure nitrogen usage instead of high-pressure cryogenic cylinders
Elimination of logistical and administrative operations
Elimination of orders and deliveries
Ready to use high technology solutions

 

Our products are designed for producing 93±3% purity medical oxygen gas from air. Our devices are used in:

Hospitals,
Policlinics,
Rehabilitation centers.

Oxygen Generators should be used by technical staff who have successfully finished their training.
