Our nitrogen gas generator is based on P.S.A Technology and that is called “PRESSURE SWING ADSORPTION’’. The main ingredient of Nitrogen Plant is CMS (CARBON MOLECULER SIEVE) and CMS is having indefinite pores on the surface, which adsorb the molecules of Oxygen, Moisture and Unwanted gases from compressed air. Nitrogen gas, which is not adsorbed into the surface of CMS comes out from adsorbed tower and collects in the surge vessel.
