Screw Compressor

Kobelco offers oil-free and oil-injected screw gas compressors, as well as Advanced Dry Screw compressors that combine the benefits of both technologies. Kobelco screw compressors have the widest application range in the world. They also offer unmatched reliability, with typical units remaining in continuous operation (unspared).

Kobelco screw compressors have capacity and pressure capabilities between those of centrifugal and reciprocating compressors. They handle inlet volume flows up to 142,000 m3/h (84,000 cfm) and discharge pressures up to 100 barg (1,500 psig). They achieve positive displacement compression using two synchronized, helical rotors. They are smooth-running and are relatively compact. Kobelco screw compressors have proven to be an effective solution for the following processes:

  • Difficult gases (dirty, polymer-forming, liquid-containing, corrosive)
  • Gases containing entrained liquids
  • Corrosive gases
  • Process that fluctuate in molecular weight, pressures and flow rates
  • Low molecular weight gases
  • And more

With accumulated experience of more than 2,100 sets of oil-free screw compressors since 1955 and over 700 sets of oil-injected screw compressors since 1974, Kobelco has demonstrated expertise in applying screw compressors for a wide variety of heavy-duty process gas applications, including oil & gas production, oil refining, petrochemical processing, steel manufacturing, general chemical and energy/power generation.
