Ask Kobelco! The Best Solution for Any Gas Compression.


As a leading manufacturer of process gas compressors, Kobelco offers all types of compressors: screw, reciprocating and centrifugal. All Kobelco compressors comply with heavy-duty process gas service requirements (API Standards). With expertise in all compressor technologies, Kobelco can recommend and engineer the optimal process gas compressor for your specific application.

SCREW GAS COMPRESSORS (API 619)
Since 1955

Kobelco offers both oil-free and oil-injected screw gas compressors. Kobelco screw compressors can compress various kinds of gas and have the widest range in the world.

Oil-free screw gas compressors are suitable for dirty and difficult gas services, such as offshore vapor recovery, refinery flare gas recovery, and petrochemical polymer forming gas. Kobelco is the most advanced oil-free screw gas compressor supplier and has the world's largest capability: up to 110,000 m3/hr (65,000 cfm). Kobelco oil-free screw gas compressors are contributing to environmental protection by recovering dirty gases that were once flared to the atmosphere.

Oil-injected screw gas compressors
feature no ratio limit and wide stepless turndown (from 100% to 20% stepless) for superior power savings. They are suitable for low molecular weight gases, high compression ratios and services with fluctuating conditions, such as hydrogen, helium, ethylene, propylene and fuel gas booster for gas turbine applications. Kobelco has the world's highest pressure capability: up to 100 barg (1,500 psig). Kobelco oil-injected screw gas compressors  have been replacing reciprocating and centrifugal compressors in various process gas services in refinery, petrochemical, energy industries.

CENTRIFUGAL GAS COMPRESSORS (API 617)
Since 1966

KOBELCO provides both integrally geared and single shaft types of centrifugal gas compressors.

Integrally geared centrifugal compressors are known for their high efficiency, compact design and competitive price. Kobelco has pioneered integrally geared centrifugal compressors for a range of process gas applications, including CO, CO2, Cl2, O2, NH3, hydrocarbon gas, natural gas, LNG, nitrogen and process air, with cryogenic services to -200 °C (-330 °F). Kobelco offers capabilities up to 300,000 m3/hr (176,000 cfm) and 80 barg (1,150 psig) with single or multiple stages.

Single shaft centrifugal compressors offer high pressure and large capacity. Kobelco has extensive experience with single shaft centrifugal compressors (multi-stage and single stage) for refinery, petrochemical (PE/PP), NH3 and methanol services. Kobelco single shaft centrifugal compressors offer capabilities up to 340,000 m3/hr (200,000 cfm) and 350 barg (5,000 psig).
