Photograph: Compressor

A compressor is a machine that utilizes rotating vanes or impellers to compress a gas. Compressors are used in various engineering applications.
We have an extensive product line-up to satisfy various needs, ranging from the large centrifugal compressors for process use that form the heart of petrochemical plants, chemical steel, and natural gas plants, as well as compact compressors used in automotive applications, electronics, IT, food processing, and aerospace industries.
Based on our long experience and advance proven technology our products are serving the customer all over the globe.

Centrifugal compressors

Process centrifugal compressors serve as the heart of plants that require high reliability. Hitachi independently develops high-efficiency compressors.

Vertically split process centrifugal compressors (BCH)
Cylindrical-shaped vertically split compressors are used for hydrogen and other light gases and applications with a high pressure of about 4-35 MPa, and are capable of high-speed stable operation at rotation speeds of up to 15,000 rotations per minute.
Horizontally Split Process Centrifugal Compressors (MCH)
The MCH-type compressor, which is suitable for pressures of up to about 4-5 MPa, has a strong casing structure, also can be split horizontally for the inner bundle maintenance without disturbing the external piping.
Centrifugal compressors for gas pipelines (PCH)
We have specialized compressors suitable for pipeline stations for transporting natural gas and other raw material gases.
Overhung Centrifugal Compressors (POB)
For low-pressure applications up to about 2 MPa, we can provide single-stage compressors with only one impeller.
Compressors for FPSO application
Due to the increasing demand for the offshore applications, Hitachi developed specialized compressors for FPSO’s. Hitachi had good experience in supplying such compressors to our customers.
