LuoMing PSA Medical Oxygen Generator 20Nm3/h 93% Purity Constant Pressure for Hospital Central Supply System

The PSA Medical Oxygen Generator is engineered with advanced Pressure Swing Adsorption (PSA) technology to deliver a consistently stable output of medical-grade oxygen at 93%±3% purity. Designed specifically for hospital central oxygen supply systems, ICU wards, and operating rooms, this system ensures uninterrupted, life-critical oxygen supply 24 hours a day, 7 days a week, 365 days a year.

Medical institutions face a critical risk when oxygen purity fluctuates: patient life safety. The Medical Oxygen generator eliminates this concern with its precision PSA twin-tower module, which utilizes high-performance Zeolite Molecular Sieve (ZMS) adsorbent to selectively remove nitrogen from compressed air. The result is a rock-steady 93%±3% medical oxygen output that meets pharmacopoeia standards, batch after batch, year after year.

The Medical Oxygen generator features a precision back-pressure regulator and surge vessel design that maintains a constant output pressure of 0.4–0.6 MPa, ensuring seamless integration with existing hospital central pipeline networks. This constant-pressure architecture eliminates the need for secondary pressure regulation devices and reduces the risk of equipment malfunction due to pressure instability.

Designed with a fully automatic PLC control system, the Medical Oxygen generator operates unattended around the clock. The twin-tower alternating cycle ensures continuous oxygen production. Integrated sensors continuously monitor purity, pressure, flow rate, and system temperature, with automatic alarm and switch-over functions that trigger if any parameter deviates from the set range.

Pressure Swing Adsorption (PSA) is a non-cryogenic air separation process that uses Zeolite Molecular Sieves to selectively adsorb nitrogen from ambient air under pressure. Compressed and dried air passes through a twin-tower module filled with ZMS. The sieve preferentially traps nitrogen molecules while allowing oxygen to pass through as the product gas. By alternating between two towers—one adsorbing while the other regenerates—the system produces a continuous stream of high-purity oxygen without the need for cryogenic temperatures or liquid oxygen storage.
