The AquaSnap® 30RA air-cooled scroll chillers have been enhanced with Puron® refrigerant, and the line have been expanded to 60 tons. The chiller line offers over 4 percent improvement over previous models on full-load efficiency and 5 percent on part load, says the company. In addition, the units exceed ASHRAE 90.1-2010 part-load standards by more than 20 percent. Features include 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.
