The CWW-M/K 181÷522 HYDROPLUS liquid Chillers and Heat Pumps, with R410A refrigerant, are designed for medium-sized domestic or industrial systems which require medium-high power, space-saving units and quiet operation. This range is ideal for indoor installation and it reduces the overall dimensions to a minimum while at the same time making installation and maintenance operations easier.
Equipped with Scroll compressors and shell and tube exchangers, these units have cooling and hydraulic circuits complete with everything necessary for quick installation and high energy efficiency.
A wide series of accessories, factory-assembled or supplied separately, such as the desuperheater or the total heat recovery, rounds off the variety of equipment in this product range.
