TRA(TM) series is the most compact 3-stage compression model of IHI Rotating Machinery Engineering. TRA(TM) series offers high energy saving, low maintenance, saving on space, and easy operation compared to rotary screw compressors. Since its launch in 2009, TRA(TM) series have continuously satisfied customers who previously used rotary screw compressors with a reduction of life cycle cost.
We have more than 1,500 aero parts designed for the most optimized centrifugal compressors to meet customers' requirements. The aerodynamic design has been analyzed by Computational Fluid Dynamics (CFD) method, the same as we use when designing jet engines and turbochargers.
By supplying the most suitable centrifugal compressors, IHI can contribute to energy saving for your plant, as well as reduce life cycle costs dramatically.
Effect of 3 stage compression
TRA(TM) series is more compact and simpler in design when compared to a rotary screw compressor. It also offers 3 stage compression in the middle-pressure range, which the rotary screw compressor does not. An increased number of compression stages can improve the compressor’s cooling performance and compression efficiency. When compared to 2 stage rotary screw compressors, TRA(TM) series offer significant energy saving by utilizing the best suited aerodynamic design.
TRA(TM) series consists of vital components, such as air cooler, main motor, control panel, gearbox, and suction filter and all of 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 gearbox provides the customers with high reliability by utilizing tilting pad journal bearing, and customized core parts(Impeller, diffuser). These parts are designed with anti-wearing technology, built for long life, and stable operation.
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.
