OCHSNER Wärmepumpen GmbH has built up a reputation as a technology leader in the heat pump sector thanks to its outstanding technical achievements and innovations. The company’s vision is to use sustainable energy to contribute to solving the challenges of our future global energy needs and of climate change. OCHSNER has a significant market share in Austria, Germany and Switzerland, as well as in many other Western and Eastern European countries. OCHSNER heat pumps are also used in China. Heat pumps from OCHSNER set standards in the industry. They regularly achieve record-breaking levels of efficiency and top values in low sound emissions. The company has smart manufacturing facilities at its main plant in Austria. OCHSNER fully endorses the principles behind Industry 4.0 and makes use of innovative production processes such as 3D printing. The company offers a complete range of products for all heat sources, as well as for heating, cooling and domestic hot water heating in the heating output range from 2 kW to 2.5 MW. OCHSNER invests some five percent of its turnover in research and development in order to maintain its leading position as an innovator.
First founded in 1872 as a manufacturer of appliances and pumps, OCHSNER Wärmepumpen GmbH was established in 1978. Since 1992, the focus has been entirely on innovative heat pump technology. The company is headed by majority shareholder and managing partner, Karl Ochsner, in conjunction with Marco Schäfer.
As an independent company, OCHSNER Energie Technik provides high capacity heat pumps which are suitable for many applications, including those related to industry and local authorities. Established in 2016, the company is dedicated solely to the development, project engineering, installation and maintenance of high capacity heat pumps. These attain flow temperatures of up to 130 °C and outputs of up to 2.5 MW.
Ochsner’s role in HYBUILD
As part of the HYBUILD project, OCHSNER is developing a speed controlled split air/water heat pump for heating and cooling in a continental climate. The OCHSNER AIR HAWK HYBUILD is particularly noted for its exceptionally quiet operation due to its proven horizontal evaporator system and the use of an alternative refrigerant, R32, with a low GWP value. To enable lower refrigerant charges, the refrigerant circuit has been optimised for this product. For DHW heating, a thermal hybrid tank (PCM) is integrated into the refrigerant circuit for the OCHSNER AIR HAWK HYBUILD. The heat pump inverter takes its power supply from the building’s DC distribution network.
