PRODUCT DESCRIPTION
The EQKR ReCooler is an integrated reversible heat pump
providing both heating and cooling. It consists of a rotary heat
exchanger and a Heat-pump unit. The ReCooler Heat-pump
has an independent control unit with heating-, cooling- and
thermal wheel demand supplied via an external control
source.
REFRIGERATION SYSTEM
The Reversible Heat-pump unit in the ReCooler is designed for
external air temperatures:
• Cooling+20to+40°C
• Heating,withelectricalheater+20to-20°C
• Heatingwithoutelectricalheater+20to-15°C

ROTOR UNIT
The rotor unit in the ReCooler is designed for heating and cooling air by utilising the temperature differences in the outdoor
air and extract air. The rotor operates to recover energy from
the extract air in combination with the heat pump unit.
OPTIONAL ELECTRIC DEFROSTING COIL
The defrost electrical heater is mainly used to shorten defrost
cycle time. It’s also used as an additional heater when evaporationtemperatureislow(<-21°C).Theelectricalheaterincludes two thermal protectors:
• Anautoreset
• Amanualreset
