The Koch & Sterzel AG was an electrical engineering major operation, by the engineers on 1 October 1904 Franz Joseph Koch and Karl August Sterzel under the name of scientific Koch & Sterzel special factory equipment and instruments in the Zwickau road 42 in Dresden was founded.
Company history
The company, which specializes in high-voltage and X-ray technology, built the first 1 megavolt test transformer in Europe for the TH Dresden (today TU Dresden ) . After the acquisition of larger areas of the former Dresden-Kaditz airfield, the transformer plant was built in Mickten / Übigau from 1922 to 1923 . In addition to the manufacture of instrument transformers , transformers and X-ray devices , Koch & Sterzel also manufactured radio devices .
The X-ray work at the Zwickau road was in the Second World War by bombing completely destroyed 1945th After the war, the transformer factory at was Washington Street under Soviet receivership asked and then dismantled .
Successor company
In 1948 the VEB Transformatoren- und Röntgenwerk (TuR) " Hermann Matern " Dresden was founded from the remnants of the former Koch & Sterzel AG , which developed into one of the most important export companies in the GDR. In 1989 the number of employees in the entire combine was around 5,000.
In 1990, significant parts of the transformer and X-ray plant were taken over by Siemens and gradually shut down or wound up. Only smaller parts of the company still operate under the Siemens flag, including the Mickten / Übigau transformer factory. The high-voltage test technology was outsourced and now works independently under the name Highvolt Prüftechnik Dresden GmbH . The TuR division “medical electrical engineering” with a focus on physical therapy operates today under the name TuR Elektromedizin GmbH in Hohen Neuendorf near Berlin.
The TuR production area measuring transducers was taken over in 1991 by Ritz Messwandler GmbH in Hamburg and continued under TuR Messwandler GmbH. In 2007 the companies TuR Messwandler GmbH Ottendorf-Okrilla , MWB Mittelspannungs GmbH Oberaurach -Kirchaich, Wandler- und Transformatorenwerk Wirges GmbH Wirges and the Ritz Messwandler GmbH Hamburg were merged under the name Ritz Instrument Transformers GmbH Hamburg.
In West Germany, due to the political situation, the plants were re-established in Essen in 1950 . The constant further development of X-ray technology then made it necessary to work with a company that was able to supply parts such as image intensifiers and X-ray tubes that were not manufactured by Koch & Sterzel . Therefore, in 1963, the contractual relationship with the Compagnie Générale De Radiologie (CGR, Paris ) followed. After the sale of the X-ray plant in Essen, it was closed in 1989. The Koch & Sterzel company was merged into the X-ray division of General Electric . In 1996, employees of the former X-ray factory in Essen founded K&S Röntgenwerk Bochum GmbH & Co. KG , which has been trading as Spellman High Voltage Electronics GmbH since 2012 after being sold .
