Long Life and low maintenance VPSA Oxygen Generator
The VPSA precess is similar with PSA. VPSA oxygen generator use air blower to supply compressed air into a adsorption tower, adsorption in low pressure and adsorption in vacuum status. Under atmosphere or slightly abover atmosphere pressure, using mixed bed composed of VPSA special molecular sieve and dryer to absorb the N2,CO2.H2O and other impurities, making oxygen accumulated and collected at the end of bed .Saturation sorption of molecular sieve bed will be desorbed in vacuum status ,so as to circularly generate high purity Oxygen (90~95%).
Compared with PSA process, VPSA has complex process equopment and higher investment but low power consumption, suitable for large scale oxygen production.
Energy for Consumption Oxygen:0.36~0.42KWh/Nm
Fully automatic control system.
The energy consumption is low,low Production Cost
Simple Process and Less Equipment
Quick Starting and Easy Stopping.
Suitable for middle and large scale oxygen production.
Low working pressure and more safety.
Long Life and low maintenance.
