TRATM is the most compact 3-stage compressor model. The TRATM;series offers energy and space saving, low maintenance and easy handling advantages compared to rotary screw compressors. Since 2009, when it was introduced to the market, the TRATM series continues to satisfy customers who have previously used rotary screw compressors by reducing the cost the life cycle.

General Information

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

IHI has 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.

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.

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.

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.
