In many industries, it is important to have the right equipment from the start; also when choosing the right heating/cooling solution. Who wants to spend a lot of time sourcing and refilling heating oil, constantly readjusting or handling chillers? This and the increasing demand for CO2 neutral, sustainable, but also cost-effective and uncomplicated solutions has led us to develop the mobile heating/cooling combination MWK40.
With our MWK40 , we have finally succeeded in creating a revolution; an automatically switching, mobile air-to-air heat pump that can heat and cool your properties in a completely CO2-neutral manner thanks to the elimination of fossil fuels and purely electric operation - and at a fraction of your previous maintenance costs. Thanks to a variable operating range between -10°C and +40°C outside temperature, nothing stands in the way of even year-round use. Our MW40 and MW80 heat pumps are designed for extreme temperature ranges down to -20°C - but without the cooling function.
Apart from setting the target temperature using the app, there is no further effort on your part. The device measures the indoor temperature drawn in and automatically regulates to your predefined desired temperature - even under extreme conditions. By dispensing with additional resistance heaters, there is also no nasty surprise in your electricity costs at the end.
Short reaction times in case of changing operating conditions exclude any impairment of persons in the object. Mobility, fast operational readiness and user-friendly control are the main features of our heat pumps.
Thanks to compact and innovative design, nothing stands in the way of rapid implementation. Our units are already prepared for operation with cold-warm air hoses and electricity, giving you full flexibility in the choice of installation site.
No tank systems, no storage of fuels and as a significant advantage: no use of chillers. Intake and exhaust ports are recessed in the housing, there are no protruding components. The heat pumps can even be stacked without hesitation! Safe loading is ensured by openings for forklift trucks or belt systems. All components are easily accessible and extremely easy to maintain thanks to removable side panels. The distribution of the conditioned air in the object can be carried out via one or several hoses at the same time. The high external pressure also allows long hose connections.
Air-to-air heat pumps can also be used for stationary applications with a permanently installed air duct system. With the help of a web application and a mobile internet connection, all unit types can be clearly managed, monitored and billed.
