CWW/K 726÷36012
Watercooled liquid Chillers and Heat Pumps with Scroll compressors and shell and tube exchangers
The CWW/K 726÷36012 series liquid Chillers and Heat Pumps, with R410A refrigerant, are designed for medium and large domestic or industrial systems which require medium-high power, space-saving units and quiet operation. These units are ideal for indoor installation and, equipped with a self contained structure, they reduce the overall dimensions to a minimum while at the same time making installation and maintenance operations easier.
The units are characterized by multi-compressor design on double cooling circuit, to reach high energy performances, reduction of current at start-up, elimination of inertial tanks and excellent silent functioning. The use of components built in large series makes them highly reliable and the management of a high number of compressors allows increased life span with reduction of machine stopping risks and easier maintenance operations. A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
The units 726÷1128 are compliant to the ErP Regulation; the units 1208÷36012 are not compliant to the ErP Regulation.
On request, units can be supplied with R452B or R454B refrigerant.
