OCHSNER heat pumps – strength from tradition

The OCHSNER family business goes way back to 1872. Many systems have been installed over the years for renowned customers all around the world, including those for the US Navy and NASA. The range of compressors includes both piston and screw compressors with ratings of up to 500 kW. OCHSNER Wärmepumpen GmbH was founded 1978 and the company has become synonymous with energy awareness, a pioneering spirit and a sense for innovation. OCHSNER was one of the first European manufacturers to manufacture heat pumps on an industrial scale. Today, the company is recognised as one of the sector's international technology leaders. Since 1992, OCHSNER has concentrated wholly on the heat pump sector.

Smart production – MADE IN AUSTRIA

OCHSNER heat pumps are manufactured exclusively in Austria using only high grade components. In this, OCHSNER pays particular attention to Industrie 4.0 and the use of advanced processes, such as 3D printing.

Today, more than 130,000 OCHSNER heat pumps are successfully deployed. A selection of reference projects are available to view > here.

Modern heating systems have to meet disparate demands. Apart from the standard functions, such as heating, cooling (on request) and DHW heating, OCHSNER also enables swimming pools to be heated, a link-up between the heat pump and a PV system, connection to the internet, hook-up to building management systems, dual mode operation in tandem with other heat generators and much more. All this is made possible by the advanced OTE control unit from OCHSNER.

Heating, cooling and domestic hot water

OCHSNER offers a comprehensive range of products for ratings from 2 to 2500 kW utilising the air, ground or water as a heat source. On request, OCHSNER heat pumps are available with a supplementary active cooling function – for which the refrigerant circuit is reversed. This creates a pleasantly cool interior without draught or noise via the existing heating system (wall embedded, underfloor or special convector unit). As required, DHW heating can be provided in conjunction with the heating heat pump or by means of the EUROPA DHW heat pump.

Efficient and tested

OCHSNER heat pumps in the GMLW series have, for many years now, achieved record-breaking levels of efficiency, top values in low noise emissions and ensure the lowest heating costs. With geothermal energy, OCHSNER is again out front where energy efficiency is concerned. When choosing a heat pump, look out for the EHPA quality seal. Only those heat pumps which have been tested by independent bodies under the strictest conditions and whose manufacturers meet specified requirements for service and documentation, are entitled to bear this quality seal.
