OCEM starts its activity in 1943, and immediately focuses itself in R&D and production of power supplies for laboratories and industry, and later on airports and power distribution.
In the 90s the company extended its markets to the airfield lighting and became a supplier of complete turn-key systems.
Since then OCEM started a quick progress on the international market, furtherly boosted by the acquisition of the companies Augier in France and Multi Electric in Chicago in U.S.A.
Nowaday OCEM has a dynamic structure which ranges over the business fields of airfield technology, energy distribution and power electronics.
A half of the personnel is busy in an intense R&D activity, in order to assure a continuous technological development of the series production and to guarantee the best customization of the special supplies.
