Nitrogen gas generators produces nitrogen gas from atmospheric air by PSA (Pressure Swing Adsorption) technology. PSA technique is a simple & reliable process of separation of nitrogen from compressed atmospheric air by adsorption of oxygen over a bed of Carbon Molecular Sieves (CMS).
CMS is an adsorbent having infinite number of small pores. The diameter of the “Bottle Necks” is in the same range as those of the molecules. Thus when CMS is used in the PSA process, an Oxygen Molecule, having a smaller diameter than a Nitrogen molecule traps in to the pores. Therefore the nitrogen is recovered to a high degree while almost all the oxygen is adsorbed.
