Airsource heat pump
Airsource heat pumps 300 KW in cascades in large-scale properties
TERRA AL 60 Max Airsource heat pump has two seperate cooling circuits with two vaporizer, two fans and two compressors. With the TWIN Technology, it features two seperate cooling circuits in one housing. Due to the separate cooling circuits, the TERRA AL 60 Max can defrost a cooling circuit, while the second one still heats up.
All Devices


  • Demand-based output adaptation with two compressors
  • Allows cooling
  • Low design height
  • Integrated heat pump Management NAVIGATOR 1.7
  • Pure outdoor installation
Air heat pumps with their high output values are an attractive alternative also for larger objects. The new iDM TERRA AL Twin is a very good example with its compact, low design, it is suitable for outdoor setup. In light of the high air throughput at heating output values of 20 kW and more, setting the system up outdoors is far easier to implement than setting it up indoors as the required air ducts are not necessary. Exclusively the controls are located in a separate control cabinet indoors to protect them from weather conditions. Such air heat pumps allow the installation of systems with up to 300 kW in cascades.
