Realized high efficiency and energy saving operation with newly developed efficient impellers, inlet guide vane, and dual control method. Installation space was drastically reduced with the integrated casing.

Highly efficient geared type is developed and supplied for air separator (separating air into nitrogen, oxygen, and argon) as the main target.

IHI is a top manufacturer of LNG reciprocating compressors, used to compress and re-liquefy boiled-off gas and send it through pressurized transfer lines.

IHI manufactures all series of turbochargers for automobiles, from small models for compacts to large versions for buses and trucks. Our accumulated production exceeds far beyond 32 million units.

Superchargers simultaneously increase engine power and reduce fuel consumption.
