Centrifugal compressor(Industrial air)

TRATM series

TRATM is the most compact 3-stage compression model of IHI Rotating Machinery Engineering. TRATM series offers high energy saving , low maintenance, saving on space and easy operation compared to rotary screw compressors. After its launch in 2009, TRATM series have continuously satisfied customers who previously used rotary screw compressors with reduction of life cycle cost.

IHI advantage


User customization

We have more than 1,500 aero parts design for the most optimized centrifugal compressors to meet customers' requirements. The aerodynamic design has been analyzed by Computational Fluid Dynamics (CFD) method, same as we use when designing jet engines and turbo chargers.


Advanced energy saving

By supplying the most suitable centrifugal compressors , IHI can contribute to energy saving for your plant, as well as reducing life cycle cost dramatically.

Effect of 3 stage compression

TRATM series is more compact and simpler in design when compare to rotary screw compressor. It also offers 3 stage compression in middle pressure range, which rotary screw compressor does not. An increased number of compression stage can improve compressor’s cooling performance and compression efficiency. When compared to 2 stage rotary screw compressors, TRATM series offer the significant energy saving by utilizing the best suited aerodynamic design.

Simple and reliable design

TRATM series consists of vital components, such as air cooler, main motor, control panel, gear box, suction filter and all these will be fitted into one compact package. This simple design allows for smaller installation space and shorter installation time. The structure of the robust gear box provides the customers with high reliability by utilizing tilting pad journal bearing, customized core parts(Impeller, diffuser). These parts are designed with anti-wearing technology, built for long life and stable operation.

100% Oil-Free

IHI centrifugal compressors supply 100% oil free air to the customers. They are classified under the latest ISO8573-1 Class 0 oil free, which is the highest grade for the purity of compressed air, by an independent third-party test house TÜV in Germany, minimizing the risk of oil contamination.
