HERAS WDP

HERAS WDP

The water-to-water heat pumps in the HERAS WDP series can be operated up to a hot water temperature of 55 °C. They have a closed machine housing and are designed for indoor installation as standard. They can also be installed outdoors with the optional weatherproof housing. 
 

The model series is equipped with two semi-hermetic reciprocating compressors, which have been specially developed for use with flammable refrigerants. Capacity control is either stepless via inverter or stepped.
 

Dual plates are used on both the evaporator and condenser sides, i.e. both refrigerant circuits are combined in one hydraulic circuit. Only with True-Dual is the respective refrigerant circuit 100% in contact with the heat transfer medium and therefore guarantees full efficiency, even when the other refrigerant circuit is not in operation (partial load).

All components used meet the highest quality standards and fulfill the applicable safety requirements. All appliances are subjected to a test bench run with a functional test before delivery. 
 

The HERAS WDP model series is also available as a booster heat pump for the high temperature range up to 80 °C. In this case, the temperature of the heat source must not fall below 20 °C.
