Your process. Our solution.

We can look back on a success story of more than 120 years in furnace construction - beginning under the name Ruhstrat, Adolf and Ernst Ruhstrat developed the first resistance-heated high-temperature furnace in 1896 in cooperation with the later Nobel Prize winner Prof. Walther Nernst from the University of Göttingen. This furnace reached temperatures of up to 3,000 °C. Just two years later Ruhstrat received commercial orders for the development and construction of customized high-temperature furnaces. 

Today and under our new name ONEJOON, our experts are developing solutions for demanding thermal processes in order to get the best properties out of high-performance and lightweight materials. With over 1000 delivered furnace plants, we enable the most diverse processes in the temperature range from 100 °C to 3,000 °C, worldwide. In addition to the optimal mapping of the thermal processes, the efficient integration of the furnaces into the production process is a top priority.
