Aerothermal unit that allows ecoGEO heat pumps to use external air as source of energy.
In installations where the geothermal option is limited or not available, the air unit AU12 is the solution. This unit allows the ecoGEO heat pumps to use external air as source of energy.
The AU12 is equipped with a very silent and highly efficient axial Ziehl-Abegg fan, that with our exclusive defrost technology allows to significantly increase the seasonal performance factor (SPF). This system completely eliminates the idle times of the heat pump during defrost cycle, because isn’t necessary to invert the refrigerant cycle or to activate external electrical heaters during the process.
