XVW – Water condensed liquid chillers with screw compressors

XVW is HiRef’s range of water-cooled chillers with screw compressors and tube bundle heat exchangers. Use of the new R1234ze refrigerant, with ultra-low GWP (Global Warming Potential), and the achievement of high energy efficiency levels, especially at partial loads, ensures the system has a low TEWI (Total Equivalent Warming Impact). The broad capacity range offered and the availability of different versions caters to a wide variety of needs. It’s possible to choose operation in chiller-only mode with evaporating tower or Dry-Cooler and operation in heat pump mode for high or low temperatures. Screw compressor allows for production of high cooling capacities with load modulation function via the special slide valve.
