Application Standard ambient temperatures
  • Standard use is for outdoor temperatures of -20 ° C - + 25 ° C 
  • Summer and transition time permanently switching depending on the outside temperature
Option Application High ambient temperatures
  •  MWK40 offers combined heating and cooling for outdoor temperatures of -10 ° C - + 40 ° C
Compact design
  • No protruding components
  • Intake and exhaust nozzles can be retracted in the housing
  • Fork sleeves for safe loading with the forklift and additional lifting eye
  • Safe stackable
Economics

On top of the inherent simplicity Kroll Air-to-Air mobile heat pumps offers a big saving on the power consumption compared to common alternatives like direct electrical heating, district heating or biofuel (biodiesel) heating with the added benefit of being fossil-free.

IncreaseD mobility

With the plug and play design and the fork lift adaptations for mobility you can be up and running in no time and the heat distribution can take place simultaneously via one or more hoses. The pressing capacity of 200-250 Pa allows long hose connections.

Serviceability

All components are easily accessible and easily serviceable thanks to removable side panels. Kropp heat pumps are delivered with a router installed by default, providing the customer with a Wi-Fi connection and control on-site.

The heat pumps come with the option of remote maintenance, diagnostic reports and operating status as well as remote software updates. Additionally the heat pumps can be equipped with remote access to operating parameters and retrieval of historical data. The
