ENERGIETECHNIK ESSEN GMBH

Vācija

Energietechnik Essen GmbH – a member of the Georgsmarienhütte Group – bases its capabilities and skills on continuous research and development as well as on experience reaching back to 1811. The Energietechnik Essen GmbH develops, produces and supplies safety-relevant high-tech products, mainly for manufacturers of power generation machinery. When the first turbo-generator was built at the start of the 20th century, the Essen-based company supplied the retaining rings. Retaining rings are placed on the ends of the rotors to fix the copper coil against the centrifugal forces created by the high rotational speeds. The oldest documents in the company's archive relating to non-magnetisable retaining rings date back to 1901. Energietechnik Essen GmbH uses two remelting units, one electroslag remelting unit and one pressurised electroslag remelting unit, to produce the materials for retaining rings.

ESAVER GMBH

Vācija

eSaver's core product is a special transformer with high power density and small size. eSaver works according to a unique principle and thus has significant differences in technology and economy compared to other energy-saving devices available on the market. By saving a substantial part of the power loss, the investment no longer takes priority because eSaver finances itself by reducing operating costs. The transformer of the eSaver has a considerably smaller size compared to conventional transformers, so that even large outputs can be realised with a smaller size. In order to keep the entire power supply network stable, the network operators supply an overvoltage that is significantly higher than the required useful voltage for consumers. This ensures that the voltages lie within the tolerance limits even in the furthest corners of the country.
