Series R® Helical Rotary Chiller Model RTAC

Dependable Performance and Reliability You Can Count On

The true workhorse of the Trane air-cooled portfolio, the Series R® Helical Rotary Chiller RTAC can be found in applications across the globe. More than 50,000 units are currently installed around the world — including over 250,000 air- and water-cooled helical rotary compressors.

Proven value honed over a quarter century

That installed base size demonstrates the value our proven direct-drive, low-speed, semi-hermetic compressor design can deliver for you. We have refined this design over 25 years of helical-rotary chiller engineering and manufacturing experience.
