The high end heat pump is suitable for buildings with heat loads between 14 and 22 kW; higher outputs are also possible with a cascade. 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. The AIR HAWK 726 features an impressive SCOP that puts it ahead of the competition (above 5 at 35°C flow temperature), as well as extremely quiet operation of the two powerful fans in the bench evaporator outdoor unit. This makes it the perfect solution even in high-density residential areas. The slimline indoor unit has a footprint of less than half a square metre. The system is controlled using the cutting-edge technology of the Ochsner Tronic Smart (OTS).
