A company in the change of time
From Ruhstrat to Eisenmann to ONEJOON
Let yourself be impressed by how the change of time has shaped our corporate culture and how a small electrical store in Göttingen has risen to become an internationally active global player that offers you the perfect solution approach for your individual requirement.
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 as well as Prof. Gustav Tammann 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 industrial furnaces.
How we rose from a small electrical store to a global player and how Ruhstrat GmbH became Eisenmann Thermal Solutions and finally ONEJOON GmbH in 2015, you will learn on your personal journey into ONEJOON's past.
