120 to 500 Tons (50 and 60Hz)
Helical Rotary refrigeration machines provide chilled water for either comfort or industrial water cooling systems.
Hermetic rotary refrigeration machines provide chilled water for either comfort or industrial water cooling systems. These air-cooled chillers for rotary refrigeration 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 rotary 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 rotary refrigeration 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
