The liquid Chillers of the CRE-FC 1025÷1045 series, with R410A refrigerant and Free-Cooling technology, are specifically designed to maximize the energy efficiency on cooling of small and medium size data centres.
During the cold months, in the FREE-COOLING operation mode, the return liquid of the system is cooled directly by forced convection of outdoor air through the condensing coil, thus saving energy by not operating the unit's Scroll compressors. A 3-way valve system is controlled by the electronic microprocessor controller, allowing functioning in CHILLER, FREE-COOLING or MIXED (simultaneously CHILLER and FREE-COOLING) modes.
The units are equipped with particular technical and design adjustments that enable an immediate and efficient use, in addition to remarkably quiet operation.
A wide range of accessories, factory fitted or supplied separately, complete the outstanding versatility and functionality of the series.
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.
