AIR 85
The heat pump is suitable for extremely high building heat loads between 48 and 73 kW. It delivers heat and DHW up to 65°C. It can also be configured for active cooling. The indoor unit has a footprint of less than half a square metre. The AIR 85 can be cascaded for higher output demands.

OTE home climate manager
With its OTE home climate manager, OCHSNER focuses on intelligent, user friendliness for the control of your heat pump system

Heating and cooling
The heat pump is the only heating system that can also perform cooling. Cooling is achieved via the heating pipes of underfloor and wall heating systems

Noise reduction through whisper quiet operation
The unique and patented whisper quiet operation reduces the sound emissions from OCHSNER horizontal split evaporators to an absolute minimum

World record for the quietest operation
The highly efficient AIR HAWK is the quietest air/water heat pump ever to be measured at the Buchs heat pump testing centre in Switzerland (measured on model Air Hawk 208). Even in standard mode, it still does not exceed the extremely low sound level of 45 dB(A), comparable to the noise level in a quiet home. This makes it the star performer for new build projects in high-density residential areas – even in neighbourhoods where the use of air/water heat pumps has thus far been almost impossible.

OTE home climate manager
OCHSNER focused on achieving an intelligent, user friendly concept in its OTE home climate manager for heat pump system control. The OTE offers you optimum convenience, energy efficiency and operational reliability. As well as all the functions for the heat pump, the OTE controller also universally controls DHW heating, cooling mode and swimming pool. Additional heat generators such as boilers and other heat consumers can also be controlled.

Heating and cooling
The heat pump is the only heating system that can also perform cooling. Cooling is achieved via the heating pipes of underfloor and wall heating systems, which absorb the higher temperature indoors and transfer it to the cooler medium (ground or water) via a heat exchanger. Essentially, there are two types of cooling: active and passive – OCHSNER heat pumps offer both – please consult the technical data for the particular type of heat pump.

Noise reduction through whisper quiet operation
The unique and patented whisper quiet operation reduces the sound emissions from OCHSNER horizontal split evaporators to an absolute minimum. You will hardly even notice them working. In silent mode, which is integrated as standard, the fan speed is reduced according to a fixed proportional function depending on the outside air temperature. This ensures that the system's already extremely low sound emissions in standard operation are reduced even further, for example in summer during DHW or pool heating. Silent mode can be set to four independent, selectable periods. The Super Silent Package is an option for all models in the AIR series and is recommended for especially sensitive areas. The optimised design derived from the aerospace industry reduces noise levels by a further 3 dB(A).
