Series R™ Helical Rotary Chiller
Model RTAC

Hermetic rotary refrigeration machines provide chilled water for either comfort or industrial water cooling systems. These air-cooled chillers are engineered for lower life cycle costs and reliability through design simplicity.

• Sizes from 140 to 500 tons.

• Helirotor™ compressor is direct drive, low speed (3600 rpm). The only moving parts are the rotors and load/unload mechanisms for high reliability and efficiency.
• Two independent refrigerant circuits.
• Tracer™ Chiller Controller and the Adaptive Control™ microprocessor provide all unit control and safety functions in a proactive control strategy.
• Units shipped ready to install with refrigerant (R-134a) and oil, need only electrical and water connections.
• Energy efficiences exceed ASHRAE 90.1 standards and the Advanced Energy Design Guide for K-12 schools .
• All units have single inlet & outlet evaporator water connections.
• BACnet™, LonTalk™, and Tracer™ system capability.
• Optional remote evaporator (140-250 tons), assembled separately at the factory
• Optional Standard or High Efficiency units
