Aircooled liquid Chillers Free-Cooling with axial fans, Scroll compressors and plate exchanger

The liquid Chillers of the CRE-FC 6205÷121060 series, with R410A refrigerant, provide advanced technology, flexible and reliable, through an intelligent control module which optimizes the operating times and the powers delivered by the Scroll compressors, according to the needs of data centre systems, where the production of chilled water is required in continuous service throughout the year. During the cold months, in FREE-COOLING operating mode, the liquid returning from the system is cooled directly, by way of the forced convection of outside air through the condensing coil, thus reducing the energy required for the Scroll compressors operation that the units are equipped with. A system of 3-way valves, controlled by the electronic microprocessor controller that manages the entire unit, can, depending on outside air temperature, operate in the CHILLER, FREE-COOLING or MIXED (CHILLER and FREE-COOLING at the same time) mode. CRE-FC 6205÷121060 allows the reduction of inrush currents generated, the elimination of inertial accumulation tanks and an excellent silent functioning, as the fans adjust their speed to the actual load of the system, providing great benefits especially at night.
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.
