What's the usage of oxygen gas keepwin compressor? 

  • Oxygen compressor for filling oxygen cylinders:
    For filling oxygen cylinder from oxygen systems, generally the pressure is high. This is done in a totally oil-free environment.

  • Oxygen compressor for medical use:
    Oxygen from a PSA or liquid oxygen source is compressed with one or two stages from 1 barg (14.5 psig) to 30 barg (435 psig) for use directly by patients.
    The oxygen is kept pure by the oxygen compressor so that it is safe for medical use.
    These oxygen compressors are usually relatively small, in the 3 to 18.5 kW range.

  • Oxygen compressor for process use:

    Oxygen for industrial processes is generally higher volume, 3,000 Nm3/hr (1,900 SCFM).

    The pressures can be medium and low, sometimes up to 150 barg (2175 psig), 200barg (2900psig).

    Is available for VSA applications at steel mills, paper plants, water treatment plants.

    The oxygen compressors are one, two, or three stages and in the power range of 50 kW up to 375 kW.
