AIR HAWK 208
The OCHSNER AIR HAWK 208 heat pump is the tailored solution for detached houses with superior energy efficiency. Thanks to the proven OCHSNER horizontal split evaporator system, the AIR HAWK 208 is exceptionally quiet in operation – in standard mode, the sound pressure level at a distance of 3 m from the outdoor unit is only 28 dB(A).

High-End Regelung OCHSNER TRONIC SMART mit App
Die OCHSNER TRONIC SMART erfüllt alle Anforderungen von heute und morgen und lässt sich direkt in ganzheitliche Konzepte der Gebäudesteuerung integrieren. Das System ist extrem einfach einzurichten und zu bedienen, auf Wunsch mit dem Smartphone oder anderen Mobilgeräten per OCHSNER App. Das Ergebnis: Ein Plus an Wohnkomfort, mehr Individualität bei den Wohnklimafunktionen und eine hohe Kundenzufriedenheit. Kernfunktionen wie der aktuelle Status der Wärmepumpe, Heizkreis, Zeitprogramm, Warmwassertemperaturen, aktuell Wetterdaten sowie die Vorhersage werden dank der optischen Bedienoberfläche anwenderfreundlich und selbsterklärend dargestellt.

With inverter technology
This series is fully modulating and continuously adjusts its output to the heat demand. This means that the heat pumps run almost without interruption during the winter season, with switching cycles reduced to a minimum. High grade compressors designed for long runtimes are used for this. This increases the service life of the heat pump. With modulating heat pumps, there is also no need for a heating buffer tank.

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.

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.

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).

Pioneer in climate protection
In the AIR HAWK, OCHSNER is already using only refrigerants with a GWP (global warming potential) well below 700, which is the maximum limit prescribed by the EU F-Gas Regulation for the year 2030 onwards. The refrigerant itself and a low charge weight reduce the CO2 equivalence, i.e. the global warming potential.

Customisable
Choose from a broad colour palette for your horizontal split evaporator for outdoor installation. The appliances are manufactured in an exclusive design. In addition to the standard colours of anthracite or white, OCHSNER offers a further 1625 shades so your heat pump can blend in perfectly with its intended surroundings.

OCHSNER air source heat pumps
OCHSNER air source heat pumps combine outstanding energy efficiency with extremely low noise emissions and futureproof, reliable technology.
