Carrier Corp. has enhanced its AquaSnap 30RA air-cooled scroll chillers with non-ozone depleting Puron refrigerant and expanded the range to 60 tons.  Carrier Corp. is a unit of United Technologies Corp. (NYSE:UTX).

The enhanced AquaSnap chiller line offers over four percent improvement over previous models on full load efficiency and five percent on part load. And, according to the company, the units exceed ASHRAE 90.1-2010 part load standards by more than 20 percent, which is critical for customers as these chillers operate in part load more than 95 percent of the time. 

Designed as a direct replacement for existing hydrochlorofluorocarbon (HCFC) refrigerant-based legacy chillers, the company says many key features were carried into the new design, including standard ComfortLink controls, an optional hydronic package covering the entire product range, single-point power in all sizes, an optional fluid loop storage tank, and standard Aero-Acoustic (low-sound) fans. New offerings include a digital scroll option as a means to provide improved load tracking and an electronic expansion valve (EXV), which provides improved capacity control and eliminates the need for liquid line solenoid valves.
