Robust modular design for greater performance

The WP Max-LoQ KK cascade heat pump is unique on the market in terms of its design. It can be used as a brine/water or water/water heat pump. LoQ technology allows source network temperatures of –15 to 15°C to be used, which is ideal for utilizing brine sources for heating purposes. The Max-LoQ KK consists of a base platform and two or three independent heat pump modules, which can be combined in any configuration from 9 to 40 kW heating capacity in a modular design. Thanks to the clever combination of fixed-speed heat pump modules with inverter heat pump modules, the cascade control integrated into the overall system can efficiently cover any operating state within a very wide performance range. Retrofitting or upgrading is also possible at any time thanks to the ratiotherm Plug’n’Play system. To do this, simply pull one of the power units out of the base chassis and replace it with a module with a different output. The environmentally friendly refrigerant allows flow temperatures of up to 72 °C.
