High efficiency cooling units for technological applications

Air condensed chillers with natural refrigerant R744 (CO2) and modulating compressors

CDA is the new range of water chillers from HiRef designed for applications that depend on energy efficiency and environment friendliness. CDA chillers offer a low environmental impact because they use CO2 as the refrigerant fluid (R744), which has a GWP (Global Warming Potential) of 1. High efficiency/footprint ratios are attained thanks to the use of inverter-controlled compressors and finned pack heat exchangers with a large heat transfer surface area and installed in a V configuration. The highest efficiency levels are achieved, both at partial and rated loads, through adiabatic saturation technology, which lowers the temperature of the air entering the coils.

Cooling range: 96 až 480 kW

Available versions:
– Chiller
– Free-Cooling chiller

Main benefits of CDA chillers:
– Very high temperature and multiple-source heat recovery
– Adiabatic saturation system
– GWP = 1
– Modulating compressors
– EC fans
