The PSA (Pressure Swing Adsorption) Nitrogen Generator operates with two pressure vessels (adsorption towers) that alternate between adsorption and regeneration cycles. Each tower is filled with Carbon Molecular Sieve (CMS), a specialized adsorbent that selectively adsorbs oxygen molecules from compressed air.Compressed air enters Tower A, where oxygen molecules are preferentially adsorbed by the CMS, while nitrogen passes through the adsorption bed and is collected as product gas. While Tower A is in the adsorption cycle, Tower B simultaneously undergoes depressurization and regeneration. During regeneration, the oxygen previously adsorbed by the CMS is desorbed and discharged to the atmosphere with the assistance of a small amount of nitrogen purge gas.When the CMS in Tower A reaches its predetermined adsorption capacity and Tower B has completed regeneration, the system automatically switches operating modes: Tower B begins adsorption while Tower A undergoes regeneration. The two towers continuously alternate between adsorption and regeneration under automatic PLC control, ensuring a continuous supply of nitrogen at the specified purity.
To ensure stable nitrogen purity and efficient long-term operation, the PSA Nitrogen Generator should be used under the following recommended conditions:
For the best operating result, the generator should be supplied with clean and stable compressed air. Proper pre-treatment, including air filtration and drying, is recommended to protect the carbon molecular sieve, maintain nitrogen purity, and extend equipment service life.
