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
