PSA Nitrogen Generator

Principle of PSA Nitrogen Generator

Under a certain pressure, using the principle of difference in the diffusion rate of oxygen and nitrogen in the air on the carbon molecular sieve, a large amount of oxygen molecules are adsorbed by the carbon molecular sieve in a short period of time, and the nitrogen molecules are enriched in the gas phase to achieve the separation of oxygen and nitrogen.
Air Surr according to the characteristics of PSA pressure swing adsorption, nitrogen equipment adopts two-tower adsorption process, one tower absorbs to produce nitrogen, the other tower desorbs and regenerates, and the cycle alternates to continuously produce high-quality nitrogen.
  • PSA Nitrogen Flow Rate：1～3000Nm /h
  • PSA Nitrogen Purity：95～99.999%
  • Adsorption Pressure：0.5～1.2MPa
  • PSA Nitrogen Pressure：0.1～1.0MPa(adjustable)
  • PSA Nitrogen Dew point：-40℃～-60℃

PSA Oxygen and Nitrogen Separation Process

Using the principle of difference in the diffusion rate of oxygen and nitrogen in the air in carbon molecular sieves, oxygen molecules are adsorbed by carbon molecular sieves in large quantities, and nitrogen is enriched in the gas phase to achieve a physical principle of psa oxygen and nitrogen separation.

The adsorption capacity of carbon molecular sieves for oxygen will be significantly different with the change of pressure, and the adsorbents in carbon molecular sieves can be desorbed by reducing the pressure. The carbon molecular sieve is regenerated, so as to achieve the repeated use of the carbon molecular sieve.

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.
