About Celex Industrietechnik
Celex Industrietechnik GmbH & Co. KG was founded in 1974 and specializes in the manufacture, assembly and distribution of systems for power generation. The product portfolio includes generator and emergency power controls for low and medium voltage (up to 500 MVA, 10 kV), power distribution systems, synchronization units, mains monitoring relays of the NW-3 series, electronic protection and control devices, combined heat and power units (CHP) and controls for diesel pumps. The switch cabinets are made from sheet-steel-enclosed housings (standard finish RAL 7032 pebble grey, protection class IP 41) and fitted out to customer requirements. The range of services extends from consulting, planning, development and project engineering through manufacturing, testing, assembly and commissioning to maintenance, training and service. Customers include hospitals, industrial plants, airports, banks, department stores and military facilities; references include, among others, Düsseldorf Airport, Essen University Hospital, Adlon Berlin and Westfalenhallen Dortmund. The head office with the registered company seat is located in Straelen; the historic production and office site is located in the Linn industrial area of Krefeld.
