Energietechnik Essen GmbH


The possibilities and abilities of Energietechnik Essen GmbH – a member of the company group Georgsmarienhütte – are based on continuous research and development as well as experiences, which go back to the year 1811.

Energietechnik Essen GmbH develops, produces and supplies security-related high-tech products, primary for manufacturers of energy machinery. When the first turbo generator was built in the beginning of the 20th century, the Essen-based company supplied the cap bands. Cap bands are being used on the rotor ends to fix the copper winding against centrifugal forces, which are being caused by high rotation speed. The oldest documents in our archive about non-magnetic cap bands are from 1901.

With two remelting assemblies, an electroslag remelting unit and a pressurised electroslag remelting unit, Energietechnik Essen GmbH produces materials for cap bands as well as other high nitrogen alloys, non-magnetic austenitic and ferric-matenstic special steels in different dimensions for a variety of applications.

Both units produce remelted ingots weighing 1,000 to 25,000 kg and in diameters measuring 400 to 1,000 mm in monitored and controlled processes.
