AquaForce® High-Efficiency, Water-Cooled, Indoor Liquid Screw Chiller
With R-134a Refrigerant
150 to 400 Nominal Tons
The 30XW units are high-efficiency, indoor water-cooled chillers with a quiet, low-vibration design featuring screw compressors. The units have excellent part load efficiency and a compact footprint less than 48 in. wide, making them great replacement units.
Water-cooled chillers within the scope of the AHRI WCCL certification program are certified in accordance with the AHRI Water-Cooled Water-Chilling and Heat Pump Water-Heating Packages Certification Program, which is based on AHRI Standard 550/590 (I-P) and AHRI Standard 551/591 (SI). Certified units may be found in the AHRI Directory at www.ahridirectory.org.
