Gas Rotary Screw Compressors

Applications

  • Collection and compression of associated gas after first and second separation stages for further transportation.
  • Conditioning of associated gas for fueling microturbines, gas reciprocating and gas turbine power plants.
  • Compression of natural gas vapors for vapor recovery units (VRU).
  • Conditioning of biogas for fueling CHP units.

COMPEX screw compressors are designed for conditioning, purifying and compression of various gases including corrosive and low-quality gases with high CO and H2S contents. The compressors feature highly efficient, reliable, safe and green operation. Today, we offer a wide range of standard rotary screw compressors and compressor stations and manufacture custom compressors as per individual customer’s requests.

Versions of COMPEX rotary screw compressors:

  • booster compressor
  • vacuum compressor

Types of compressors:

  • oil-flooded
  • dry
  • oil-flooded with separate lubrication system
