The liquid Chillers of the CREI-E 1025÷1045 series, with R410A refrigerant, are specifically designed for small and medium size data centres.
They are contained in a peraluman structure corrosion-resistant over time.
All units feature A CLASS energy efficiency and are equipped with Inverter control on Scroll compressor for a better efficiency at partial loads (SEPR/ESEER/IPLV). The Microchannel condensing coils ensure an high efficiency (high EER), having a better heat exchange than traditional coils.
The units are equipped with particular technical and design adjustments that enable an immediate and efficient use, in addition to remarkably quiet operation.
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.
