WATERCOOLED LIQUID CHILLERS WITH SCROLL COMPRESSORS AND SHELL AND TUBE EXCHANGERS
The CRW 6205F÷121060F series liquid Chillers, with R410A refrigerant, are specifically designed for medium-large size data centres. 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. CRW 6205F÷121060F is an extremely flexible and reliable machine: an intelligent control module optimizes functioning times and supplied power from the Scroll compressors based on heat load demands in the system and providing elevated energy efficiency. The unit can obtain an high energy yield, elimination of generated power surges and elimination of inertial accumulation tanks. The use of components built in large series, making them highly reliable, and management of an high number of compressors allows increased life span and reduction of unit's stopping risks: a faulty compressor will not compromise cooler functioning, which will continue to work with decreased power levels. In addition, maintenance operations are decisively reduced due to the high reliability of the machines and their components.
