The TRA™ Series is a compact, oil-free three-stage centrifugal compressor engineered for high-efficiency operation, reduced energy consumption, and lower maintenance in industrial applications. With its streamlined package design, the TRA™ integrates key components — including the air cooler, motor, suction filter, control panel, and gearbox — into one robust unit that minimizes both installation space and setup time.

Featuring more than 1,500 customizable aerodynamic designs analyzed using CFD (Computational Fluid Dynamics), the TRA™ Series provides tailored performance to meet diverse plant requirements. Its three-stage compression structure delivers superior cooling and energy efficiency, outperforming rotary screw compressors in both middle-pressure range and lifecycle cost reduction.

Equipped with tilting pad journal bearings and anti-wear impellers and diffusers, the TRA™ ensures long-term reliability with significantly lower servicing needs. Certified ISO 8573-1 Class 0 by TÜV Germany, it delivers 100% oil-free air — making it an ideal solution for automotive, electronics, chemical, and food manufacturing environments.
