PSA Oxygen Generator

Principle of PSA Oxygen Generator

The compressed air enters the adsorption tower equipped with zeolite molecular sieve after the air purification system removes impurities such as oil, water, and dust. 

The nitrogen, carbon dioxide, and water vapor in the air are absorbed by the molecular sieve, and the oxygen passes through the adsorbent due to the high diffusion rate.  To realize the separation of oxygen and nitrogen. 

When the nitrogen and other impurities adsorbed in the adsorption tower are saturated, the pressure is reduced to desorb and regenerate the zeolite molecular sieve, which can be used repeatedly. Two adsorption towers work in cycle to continuously produce high-quality oxygen.
  • Oxygen output: 5～200 Nm 3 /h
  • Oxygen purity: 90%～95%
  • Oxygen pressure: 0.1～0.4 MPa (adjustable)
  • Dew point: - 40°C or - 60°C

Application of PSA Oxygen Generator

PSA (Pressure Swing Adsorption) Oxygen Generators are extensively employed in diverse industrial and medical applications for on-site oxygen production. In healthcare, they are used to supply medical-grade oxygen to hospitals and clinics for patient care, respiratory support, and surgical procedures. 

Additionally, in the metal industry, PSA Oxygen Generators aid in enhancing combustion processes, like flame cutting and welding, by providing a consistent source of high-purity oxygen. They are also utilized in wastewater treatment, ozone generation, and various chemical processes where oxygen enrichment is essential for improving efficiency and reducing costs.

What is the service life of the molecular sieve?
The service life of the molecular sieve depends on the quality of the intake compressed air. In case the recommended standards are kept, the sieve can be operated for up to 8 years and even considerably longer.
What are the maintenance expenses for the PSA N2/O2 generators ?
In case of a use of 24 hours daily, the elements of the internal filter must be exchanged, in rotation, every six months. The valves must be exchanged every five years. The maintenance of air compressor are according to the recommendations of the air compressor manufacturer.
What are the key benefits of on-site N2/O2 generators compared to delivered gas?
  • You save up to 80% on the cost of the nitrogen or oxygen compared to buying  in bulk.
  • Payback is usually under 12 months, and the product has a typical lifetime over 10 years.
  • A constant supply is ensured: you never have to worry about a delivery not getting to you in time again.
  • Save space & minimize risk and handling errors: no need for gas bottles/liquid nitrogen tank in the yard.
  • Simplify administration to save time & money with no weekly deliveries to manage.
  • Very low running costs: uses your compressed air supply.
Are PSA N2/O2 generators safe?
Yes. As the generator does not add or take anything away from the atmospheric air, you could have one running in a closed room with no change to the overall content of the atmosphere. They also negate the need to store and move potentially dangerous high pressure cylinders on site.
