The highly efficient high end heat pump is suitable for buildings with heat loads between 22 and 43 kW. Up to four units can be connected as fully modulating units in a cascade and therefore cover heat loads of up to 160 kW, for example in apartment buildings, or commercial or office buildings. The AIR HAWK 1850 is impressive in its output category with particularly low noise emissions. It works with a speed controlled compressor and delivers heat and DHW up to 60°C; it can also be used for energy saving surface cooling and for active air conditioning and room dehumidification via fan coils. It is equipped with a climate friendly refrigerant and has received the Energy Genius 2023 innovation award. The OCHSNER TRONIC SMART (OTS) control system enables the AIR HAWK 1850 to be controlled conveniently via an app.
