PSA N2 description

    CanGas® pressure swing adsorption nitrogen generation system produces 0.1~50,000Nm3/h gaseous nitrogen at purity of 80%~99.9995%@6bar. The system incorporates screw air compressor, refrigerant air dryer and online compressed air filters, PSA nitrogen generator, air buffer tank and nitrogen buffer tank, and involving monitoring and controlling instruments.

    The atmosphere, which is inexhaustible in supply and always available for use in any corner in all around the world, is used as raw material in PSA technology to produce gaseous nitrogen.

    Compressed air is purified through the air dryer and filters to a certain level for main generator to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of work demand for air compressor. The generator produces nitrogen with PSA (pressure swing adsorption) technology, which is a time proven nitrogen generation method. Gaseoue nitrogen of desired purity at 95%~99.9995% is delivered to nitrogen buffer tank for smooth supply of product gas. Nitrogen in buffer tank is maintained at 6barg pressure. It is adjustable for your needs downstream through a pressure regulator valve.
