Welcome to Energietechnik Essen GmbH

Energietechnik Essen GmbH stands for specialised and safety-relevant high-tech products:

Retaining rings are installed at the end of rotors to hold the copper windings in place against the centrifugal forces caused by the high rotational speeds. The main customers for retaining rings are, logically, power generation machinery makers.

Nitrogen-alloyed steels, i.e. high nitrogen-alloyed, non-magnetic austenitic and ferritic-martensitic special steels are used in, among other applications, ball screw assemblies to adjust elevators on aircraft. Other main areas of use include ball and roller bearings, instruments for the medical industry, and high-grade mechanical engineering products.

Two remelting facilities - one for electro slag remelting and the other for pressure electro slag remelting - as well as an expanding press provide the capability to produce to the highest quality standard. Machining and heat treatment capabilities complement the spectrum of services offered by Energietechnik Essen GmbH.
