Air-cooled chillers designed to reduce energy consumption

20 September, 2005

Free-cooling versions of the RAS series of air-cooled chillers can dramatically reduce energy consumption.

Delrac’s RAS series of air-cooled chillers comprises 12 models with cooling capacities from 330 to 660 kW. Each model has two semi-hermetic reciprocating compressors and two separate cooling circuits. They are offered with R407C and R134a refrigerant. Free-cooling versions can produce cold water using ambient temperature for cooling when it is low enough. Free cooling is enabled when the temperature difference between the inlet water and outside air is at least 2 K. The compressors are gradually unloaded until the progressive drop in temperature causes them to shut down completely. Unit frames are fully weatherproof and made of anodised aluminium profiles. The compressor housing panelling is of Peralluman. sales@delrac-london.co.uk
