Nitrogen generators N-GEN
PSA Nitrogen generators
Nitrogen generators and Oxygen generators extract the available nitrogen/oxygen in the ambient air from the other gases by applying the Pressure Swing Adsorption (PSA) technology. The first step in the PSA process is compressed air passing through a combination of filters and an activated carbon tower with the purpose of removing dust, entrained oil and water. The purified air is then directed to one of two adsorption vessels that are packed with carbon molecular sieves (CMS). The remaining impurities such as carbon dioxide and residual moisture are adsorbed by the CMS at the entrance of the adsorbent bed. PSA process in oxygen generators is very similar than in nitrogen generators. Just carbon molecular sieves (CMS) are replaced with molecular sieves (MS).
