The PSA oxygen technology process for the generation of oxygen gas from compressed air utilizes the ability of Zeolite Molecular Sieve (ZMS) to absorb mainly nitrogen. While nitrogen concentrates in the pore system of the ZMS, purity oxygen gas is produced as a product.

*Over 24 years’ manufacturing& engineering experience in oxgyen generator, time-proven onsite systems.
*High efficient and high quality of molecular sieve and proprietary PSA energy saving technology of the oxygen generator can reduce compressed air consumption.30% cost saving compared to bulk liquid oxygenand 50% cost saving compared to oxygencylinders.
*Fully automated oxygen generator is low maintenance and ideal for a variety of applications. *Optional CANBUS touch screen central monitoring and control system equipped in the oxygen generator enable all working status under online control.
*Cabinet & Packaged type available.
*Turn-key solution, all systems of the oxygen generator pre-tested.
