Working Mechanism
The PSA oxygen generator uses zeolites AS adsorbent materials to trap oxygen at high pressure in one adsorption tower, the process then swings to low pressure to desorb the oxygen while the other adsorption tower starts with adsorption process. The two process then alternate in the two adsorption towers, realized with control valves and PLC to have continuous production of qualified oxygen.
Vacuum Pressure Swing Adsorption (VPSA) technology can produce the desired gas much more efficiently. It draws the gas through the separation process with a vacuum, generated by a blower, The systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas.

Past Projects:

①VPSA-700 for Brazil non-ferrous smeltery project.
②VPSA-1000 for China pharmaceutical company.
③VPSA-2000 for Vietnam ceramic industry.
④VPSA-3000 for India steel smeltery project.
⑤VPSA-5000 for China hospital project.
