Mobile air-to-air heat pump MWK40 with cooling
Mobile air-to-air heat pump MWK40 with cooling
The MWK40 air-to-air heat pump combines mobile heating and cooling fully electrically – without fuels, without chillers, without extra adjustment. Fully automatic operation and a CO₂-neutral solution make it a cost-efficient and easy-to-use option for demanding environments.
The unit’s operating temperature range extends from –10 °C to +40 °C, so it can be used almost all year round. The MWK40 adjusts the temperature automatically according to a preset target and reacts quickly to changing conditions – without separate resistance heaters or surprises on the electricity bill.
The MWK40 heat pump is an excellent choice for:
- construction sites
- warehouses and production halls
- events and festivals
Mobile heat pump MWK40 is a fully electric air-to-air heat pump that both heats and cools. The rated heating output is 42.9 kW, and the unit operates at outdoor temperatures of -10…+40 °C.

Mobile heat pump MWK40 – how it works
The unit combines mobile heating and cooling fully electrically. Therefore, you need no fuels, no separate chillers and no extra adjustment.
The pump adjusts the temperature automatically according to a preset target. In addition, it reacts quickly to changing conditions.
The unit uses no separate resistance heaters. As a result, electricity consumption stays predictable: the maximum energy consumption is 13.9 kW.

Applications
The operating range of -10…+40 °C allows use almost all year round. For example, the unit cools in summer and heats in winter.
The pump suits construction sites, warehouses and production halls, as well as events and festival tents.
It also serves agriculture and municipal premises, either temporarily or permanently.
In addition, the compact design and quick start-up bring flexibility when the use of a space changes.

Mobile heat pump MWK40 – efficiency and model choice
The COPh is 3.31 at +7 °C and 2.24 at -7 °C. The seasonal efficiency SCOPh is 2.88.
For heating only, the MW40 is suitable, as its operating range extends to -20 °C. For larger sites, however, there is the MW80 with 96.7 kW.
For long hose lines, you can boost the air transfer with duct fans. You can find all models on the air-to-air heat pumps page.
Safety
The unit weighs 1020 kg and measures 2.4 x 1.2 x 2.2 m. Therefore, move it with suitable lifting equipment onto a level base with sufficient load-bearing capacity.
The IP44 enclosure protects against splashing water. A qualified refrigeration technician services the refrigerant circuit.
A qualified electrician makes the electrical connections. You can find the requirements for electrical work on the Tukes website.
