Our PSA oxygen generator can separate oxygen from compressed air utilizing zeolite molecular sieve (ZMS) under pressurization. For PSA oxygen generator, the compressed air is first purified to remove the moisture, oil and dust. Then the purified air will pass through adsorption tower filled with ZMS. As nitrogen has a higher diffusion rate in ZMS pores, the sieve will adsorb the nitrogen and moisture over oxygen, allowing the oxygen to pass as product gas at pressure. After de-pressurizing, the sieve releases adsorbed gases into the atmosphere, and the process can then be repeated.
Two adsorption tower will be installed in parallel in PSA oxygen generator, one tower begins the adsorption phase while other tower regenerates by de-pressurizing. The PLC controller manages process valves with built-in logic for an automatic stop/start for continuous oxygen production. The whole system is composed of purification system for compressed air, air condenser, adsorption tower and oxygen buffer tank. PSA oxygen generation technology is widely used in industrial and medical applications for its efficiency, cost-effectiveness and low maintenance requirements.
