Hitachi has supplied over 800 centrifugal compressors around the globe, since the first one was completed in 1911.
Centrifugal compressors meet various needs, and their main applications are in oil refineries, chemical plants, fertilizer plants, natural gas plants, steel plants, etc. We are confident that we can increase customers' satisfaction through our long, extensive experience and advanced technologies.
Compressors serves as heart of any process plant, so they are designed to be highly reliable, highly energy-efficient, and low-cost, considering the world energy situation.
