  • PSA Nitrogen Generator
    PSA Nitrogen Generator. Less Cost - Generate your own nitrogen for about $0.20/ccf. NO Contracts, No wasted nitrogen, NO Fees....

  • The various models of PSA nitrogen generation systems
    offered by GCS generate nitrogen at purities ranging from
    95 – 99.999%, with a max pressure drop of only 1 bar.
    Various sizes are offered with flowrates ranging from 5cfm
    to >200cfm in order to meet your specific nitrogen needs.
    Compressed air is passed through a refrigerated air dryer
    and a four-step filtration process for optimal performance
    and lifespan of the PSA unit. An air buffer is incorporated
    for smooth supply of compressed air, thus reducing
    fluctuation of load demands at the air compressor. The
    generator produces nitrogen with PSA (pressure swing
    adsorption) technology, which is a time proven nitrogen
    generation method. Nitrogen at the desired purity is
    delivered to the nitrogen buffer tank for smooth supply at a
    constant purity and flow rate. The nitrogen buffer tank is
    maintained at certain pressure, and is adjustable to your
    needs through a pressure regulator valve.
    The principles of PSA nitrogen generation are adsorption
    and diffusion. Each gas has a characteristic adsorption rate
    that is adsorbed by the Carbon Molecular Sieve (CMS). The
    CMS has a large surface area that is covered in micropores
    and passageways. Since oxygen has a higher adsorption rate
    than nitrogen, when compressed air flows through the
    CMS, the nitrogen molecules are able to pass through this
    large surface freely, while oxygen molecules are adsorbed to
    these pores.
    After the CMS is saturated with oxygen, it is depressurized
    to regenerate for the next cycle. We use two towers filled
    with CMS to produce a continuous stream of nitrogen.
    During depressurization, the nitrogen of lower purity is
    transferred to the adjacent tower, which is called pressure
    equalization. Pressure equalization is key to higher
    efficiency and less energy consumption.
