The only general manufacturer in the world supplying all types of compressors
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
Kobelco has manufactured reciprocating compressors since 1915 and now has an installed base of more than 2,300 units around the globe. Kobelco reciprocating compressors (API 618) have been serving in a wide variety of heavy industry applications: oil refining, natural gas, petrochemical and energy. Recently, they have been supplied for cryogenic services, such as LNG, BOG [-160 °C (-260 °F)], ethylene BOG [-100 °C (-160 °F)].
Kobelco provides both integrally geared and single shaft types of centrifugal gas compressors. Kobelco integrally geared centrifugal compressors include SuperTurbo for process gas services with API 617 and Air Services with API 672.
Kobelco single-shaft centrifugal compressors are API 617 compliant. Kobelco centrifugal compressors are widely used for various process gas and air services in oil refining, petrochemical, air separation, plant and instrument air and energy services. The application range for centrifugal compressors extends up to 100 barg (1,500 psi) and 450,000 m3/h (265,000 cfm).
Since 1966, Kobelco has successfully installed more than 1,000 units in wide variety of applications / variety of applications.
