OCHSNER AIR HAWK 518

9 - 14 kW

The high end heat pump is suitable for buildings with heat loads between 9 and 14 kW. It works with a speed controlled compressor and delivers heat and DHW up to 65°C. It can also be used for energy saving surface cooling and for active air conditioning and room dehumidification via fan coils. Minimal outdoor unit noise emissions make the heat pump the perfect solution in high-density residential areas. The slimline indoor unit has a footprint of less than half a square metre. The AIR HAWK 518 is equipped with the OCHSNER TRONIC SMART (OTS) control system and can be controlled via an app. The AIR HAWK series was honoured with the Plus X Award in the categories innovation, high quality, ease of use, functionality and ecology.
