The A CLASS energy efficiency liquid Chillers of the CREI-E 2060÷4210 series, with R410A refrigerant, are specifically designed for medium size data centres.
They are equipped with axial fans, Inverter Scroll compressors, Microchannel condensing coils and plate exchanger, even in the super silent version. The Microchannel condensing coils ensure an high efficiency (high EER), having a better heat exchange than traditional coils. A better efficiency at partial loads (SEPR/ESEER/IPLV) is guaranteed by the Inverter control on Scroll compressor. Furthermore, Inverter control is also available on circulating pump and fans (EC) for a further efficiency improvement. 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.

Versions

  • CREI-E - Cooling only
  • CREI-E/SSL - Super silenced cooling only

Features
