The liquid Chillers of the CRE 2050÷4190 series, with R410A refrigerant, are specifically designed for medium size data centres.
Equipped with axial fans, Scroll compressors and plate exchanger, even in the super silent version, these units can be completed by a hydraulic circuit with tank, with pump, or with tank and pump. 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.


  • CRE - Cooling only
  • CRE/SSL - Super silenced cooling only

Power range
