About EGESIM
EGESIM was founded in Izmir in 1993 and is a corporate group for industrial electrical engineering, automation and mechanical plant construction. The company designs and manufactures low- and medium-voltage switchgear (0.4–0.69 kV and 3.3–36 kV respectively), MCC, converter and PLC control cabinets, reactive power compensation systems, RC filters and surge arresters, as well as substations and outdoor switchgear from 52 kV to 220 kV. As a certified Siemens system integrator and SIVACON Technology Partner, switchgear cabinets are manufactured among others based on SIVACON S8, Sinamics converters and S7 PLC systems. In addition, EGESIM undertakes turnkey industrial plants (EPC), geothermal power plants based on ORC technology in cooperation with Atlas Copco, as well as operation, service and maintenance services. The group employs more than 400 staff, including 45 engineers, on approximately 25,000 m² of built-up and 27,000 m² of open area. The German location of Egesim GmbH is in Eresing, about 50 km from Munich.
