Special features:

Inverter control:

The WP Max-HiQ series can cover a very wide range of heating and cooling capacities thanks to the standard integrated speed control using inverter technology. This opens up a wide range of applications. The inverter technology also allows, for example, power regulation to use PV electricity for heating or cooling as required. This heat pump offers you maximum savings potential, as it always delivers the right output and automatically adapts to the current energy requirements of the living space at any time of year.

Flexible source network temperatures:

Thanks to the WP Max-HiQ being equipped with ratiotherm’s patented grid technology, users can tap into any heat source for the heat pump. Even if the source temperatures constantly change within a temperature range of 10-55°C (e.g., process heat during various work steps), the WP Max-HiQ always operates at the optimum operating point. For the operation of the system, this means minimized operating costs with maximum coefficient of performance (COP).
