Hitachi has manufactured more than 3,000 compressor sets of various types including 700 sets of centrifugal type over the past 85 years for complete range of industrial facilities, including refineries, chemical and petrochemical plants, natural gas processing and transmission plants, and iron and steel mills.
Compressors as the heart of the plant have been required to be more high reliable and also to be more high efficiency in order to save energy in the plant, because the rising cost of energy has been serious problem in the world in recent decade.
To satisfy above requirement, Hitachi has been researched and developed of the compressor with high efficiency, and up to now, many compressors have been supplied and are operating successfully in the world.
