Nitrogen & Oxygen generator

Nitrogen & Oxygen generator

PSA Nitrogen Generator for Oil&Gas, Electronics, Chemical and Pharmaceutical


Product introduction

Pressure swing adsorption(PSA)nitrogen generator is an automatic equipment that uses carbon molecular sieve as adsorbent, pressure reduction desorption prin- ciple to adsorb oxygen from the air, thereby separating nitrogen.


Technical indicators

Nitrogen production:1~5000Nm³/h(Standard State)

Nitrogen purity:90%~99.9995%(National Standard Non-oxygen Content)

Nitrogen pressure:0.01~0.8Mpa(Table Pressure Stable And Adjustable)

Nitrogen dew point:-40℃~-70℃(Atmospheric Dew Point)

High quality carbon molecular sieve

High density, compact spring loaded, top/bottom balance, protected by a dedicated pressure sensor

Product characteristics

1. Raw material air is taken from nature. Nitrogen can be produced by supplying compressed air and power.

2. Nitrogen purity can be adjusted conveniently and arbitrarily between 90% and 99.999%.

3. The equipment is highly automated, produces gas quickly, and can be unattended. Nitrogen can be produced within 10-15 minutes of startup.

4. The equipment process is simple, occupies a small area, consumes less energy and costs.

5. Molecular sieves are filled by snowstorm method to avoid the pulverization of molecular sieves caused by high-pressure airflow impact and ensure the long-term use of molecular sieves.

6. On-line inspection of imported analyzer with high accuracy and maintenance-free.
