The company was founded in 1928 as a repair workshop for turbines and generators. Kössler later began developing its own turbines and controllers and steadily improved its market position. In the 1980s, the company was honoured by the government of the Republic of Austria for its activities in the small hydropower sector. At the same time, Kössler increased its sales markets and now generates 20 % of its sales on the Austrian market and 80 % in Europe and overseas. The company also received an export award from the chamber of commerce in 2005 for its high export rate.
2007 was the merger with the Voith Hydro GmbH & Co KG St. Pölten. The aim is to cope with the growing number of inquires for the renewable energy of Small Hydro Power. Kössler will be the centre for Small Hydro with the present customer oriented and competitive structure and the background of Voith’s technology.
Kössler stands for continuous and sustainable business growth. About 100 employees design, manufacture and install about 40 to 50 new turbine arrangements per year, both in Austria and abroad.
