Water-water heat pump
with natural refrigerant

Heating or cooling

Optimum conditions all year round

Our reversible water-to-water heat pumps create optimum temperatures under changing conditions, as they can either cool or heat. In addition to the wide range of available performance classes, they are characterised by their extensive customisability in our in-house production facility – perfect for every requirement!


Even the highest
cover the highest demands

Up to 4 heat pumps can be easily combined to form a multi-machine in order to achieve a particularly high output capacity. The individual machines can be installed separately or together on a space-saving frame.

High or highly fluctuating loads can be efficiently covered with the multi-machine by switching individual heat pumps on or off. The individual machines are only connected to each other on the hot/cooling water side and operate autonomously. This redundancy further increases reliability.
