CWW-M/SZ/K 724-P÷1306-P

Watercooled liquid Chillers and Heat Pumps with Scroll compressors and plate exchangers

The CWW-M/SZ/K 724-P÷1306-P NEXTPOWER series, with R410A refrigerant, Scroll compressors and plate exchangers, is designed for medium and large industrial systems requiring high power, space-saving units and quiet operation.
These units are ideal for indoor installation reducing the overall dimensions to a minimum while at the same time making installation and maintenance operations easier.
High reliability is the key plus of NEXTPOWER, thanks to the use of components built in large series and the management of several compressors allowing an increased compressor life span and the reduction of machine stopping risks: a faulty compressor will not compromise the functioning of the unit, that will continue to work with decreased power levels.
NEXTPOWER obtains high energy yield with elevated ESEER values; thanks to the high partialization and the intelligent control module, it doesn't require inertial storage tank.

The units feature 460V power supply and 60Hz frequency.
