TRA series

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



General Information

Customization for the customer - TRATM

IHI DALGAKIRAN has more than 1,500 aero parts designs for centrifugal compressors optimized to meet the requirements of the customer. The aerodynamic design is performed by the Computerized Fluid Dynamics (CFD) method we use while designing jet engines and turbochargers.

Advanced Energy Saving

By supplying the most suitable centrifugal compressors, IHI DALGAKIRAN may contribute to your plant's energy savings and significantly reduce the cost of life cycle.

There are more than 8,000 IHI DALGAKIRAN centrifugal compressors currently operating worldwide. IHI DALGAKIRAN is exploring the possibilities for developing centrifugal compressors that meet the ever-changing requirements of each customer as per the requirements of customers around the world.

IHI DALGAKIRAN is proud to offer reference to rotary screw product NOT centrifugal tailored to different areas, such as jet engines, turbochargers and compressors, as one of the world's leading manufacturers of rotary machinery.

One of the most important features of IHI DALGAKIRAN centrifugal compressors is "Customization for the user". The IHI DALGAKIRANcentrifugal compressor may provide optimized designs that meet your facility's varying air requirements by combining more than 1,500 designed aero components developed using Computerized Fluid Dynamics (CFD) methods based on IHI DALGAKIRAN's extensive experience. IHI DALGAKIRAN will always offer you the "best compressor solution".

Effect of 3 phase compression - TRATM

The TRA series has a more compact and simple design than rotary screw compressors. It also provides 3-stage compression in the medium pressure range, which is not possible with rotary screw compressors. Increasing the number of compression stages may improve the compressor's cooling performance and compression efficiency. The TRA series provides significant cost savings with respect to 2-stage rotary compressors thanks to their optimal aerodynamic design.

Simple And Reliable Design - TRATM

TRA 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.
