KNA PSA Nitrogen Generator

How it works:
Ambitious clean KNA PSA nitrogen plant, according to the principle of pressure swing adsorption, high-quality carbon molecular sieve as adsorbent, to a certain pressure, due to kinetic effects of oxygen in microporous carbon molecular sieve nitrogen in the diffusion rate is much greater than in adsorption equilibrium is not reached, oxygen was a lot of carbon molecular sieve adsorption, nitrogen is enriched in the gas phase divided, to separate oxygen and nitrogen. As the carbon molecular sieve adsorption of oxygen is easy with the pressure difference between the two have significant differences, lower pressure, carbon molecular sieve can be desorption of oxygen molecules, so that the carbon molecular sieve regeneration cycle can be repeated use. Dry adsorption process using two towers, one tower of nitrogen adsorption capacity, a tower desorption regeneration, through the PLC program control pneumatic valves open and close, so that the two towers alternating cycle, continuous output of high-quality nitrogen.
Broad Product features:
★ imported pneumatic angle seat valve, life up to 200 million times.
★ imported PLC intelligent control, easy operation, stable operation.
★ reasonable internal components, air distribution, high-speed airflow to reduce the impact.
★ specific molecular sieve protection measures, to extend the life of the carbon molecular sieve.
★ nitrogen emptying automatic interlock devices to ensure the quality of the product nitrogen.
★ Nitrogen output: 5 ~ 2500Nm3 / h
★ Nitrogen purity: 95 ~ 99.999%
★ nitrogen pressure: 0 ~ 0.7MPa (providing 0.7 ~ 15MPa)
★ atmospheric dew point: ≤ -48 ℃
