R290 superblock

Industrial refrigeration compact units

Packaged refrigeration units for refrigerated storage designed for outdoor installation through a cold room wall


Superblock series are compact refrigeration units for outdoors and  wall-mounting installation of cold rooms.

R290 superblock series combines the latest refrigeration technologies with traditional effective solutions. They are able to operate under extreme weather conditions with minimum maintenance needs. Superblock units are environmentally friendly: providing high performance, a low ecological refrigerant load in hermetic refrigeration circuit and low noise emission rate.

  • ACH series: high temperature application for cold rooms, working rooms, pre cold rooms and refrigerated loading docks (5 to 20ºC)
  • MCH series: preservation of generic products at medium temperature cold rooms (-5 to 5ºC)
  • HCH series: positive temperature cold rooms with high humidity needs, e.g. fruits and vegetables store (0 to 10ºC)
  • BCH series: Negative temperature cold rooms for freezing (-35 to -15ºC)
