The HRC 70 operates with a new fluorine-free non-toxic refrigerant, which would mean in case of loss no environmental impact and therefore does not cause the greenhouse effect. It is a gas which is also present as part of our air. The refrigerant circuit in the HRC 70 is closed and generally requires no maintenance. These are another very significant benefits for the protection of the environment of our planet.

The pilot includes all technical components that are required for optimal and energy-saving function of the heat pump. Electronic control allows a variety of settings and on the other hand the complete hydraulic system with circulating pumps and from the performance class of 17 kW  a separate buffer tank of 60 liters. These basically an electric auxiliary heater of 6kW, which can be switched on in steps of 2 kW, if this should be necessary in extreme cold . This additional heating can be programmed on and off.

The HRC 70 is available in the power range 7-140 kW output, which come two mutually corresponding high pressure compressors for use from the heating power of 17 kW for the first time. They are split into 1 / 3rd and 2 / 3rd of the heat output. The heat pump works in 4 stages.
When heat demand is low and when it is not so cold, only the small compressor is operating, it gets colder the large compressor is switched on, it is even colder on the small compressor to and in extreme cold, the electric auxiliary heater switched in 3 steps as needed to.
The result is also enormous energy savings over the seasonal heating demand.
