A CLASS energy efficiency aircooled liquid Chillers with axial fans, Inverter Scroll compressors, Microchannel condensing coils and plate exchanger
The CREI-E 4225÷6760 units, with R410A refrigerant, are characterized by the highest efficiency, all in A CLASS energy efficiency, featuring Microchannel condensing coils and Inverter Scroll compressor: an intelligent control module optimizes functioning times and supplied power from the Scroll compressors based on heat load demands in the system. In this way, the machine can obtain high energy yield with decisively elevated SEPR/ESEER/IPLV values, elimination of generated power surges, elimination of inertial accumulation tanks and excellent silent functioning, since the fans adjust their speed to the actual system load, providing benefits especially during the night. The use of components built in large series making them highly reliable and management of an elevated number of compressors allows increased life span and reduction of unit stopping risks: a faulty compressor will not compromise cooler functioning, which will continue to function with decreased power levels. In addition, maintenance operations are decisively reduced due to the high reliability of the machines and their components.
Units are featured as standard with an electronic proportional device that ensures efficient continuous functioning of the unit with outside air temperature down to –20°C.
