Key Parameters 200-6,000 Nm3/h (per set) (Higher capacity can be achieved with combined multiple sets). Oxygen purity: 21-95%. Power consumption: 0.3-0.36 kWh/Nm3 with oxygen purity of 90%. Vacuum Pressure Swing Adsorption (VPSA) technology can produce the desired gas(es) much more efficiently. The system segregates certain gases from a gaseous mixture at near ambient pressure; the process then swings to a vacuum to regenerate the adsorbent material, zeolite molecular sieves. It draws the gas through the separation process with a vacuum, typically generated by a blower, The systems apply pressurized gas to the separation process and also apply a vacuum to the purge gas. Suzhou Doer Gas & Chemical Equipment (DoerCryo) specializes in Atmospheric Cryogenic Storage Systems (Full Containment/Vacuum-insulated/MicroBulk Tanks for LNG, LOX, LIN, LAR, LCO2, LN2O, LC2H4...), VPSA Oxygen Generators/Plant, & Air Separation Units (ASU). We're ISO9001, 14001, 45001, ASME certified, having rich experience working with large engineering/energy enterprises, having been well received home and abroad.
