Our Maritime History

The history of Zenitel dates back to 1901, when a group of Belgian entrepreneurs founded C.T.S.F. , Compagnie Générale de Télégraphie sans Fil. Following World War II, the company (then named S.A.I.T. Electronics, Société Anonyme Internationale de Télégraphie), entered into various collaboration agreements with other companies including Radio Holland N.V. and Norsk Marconikompagnie A/S. In 1992, the successful partnership with Radio Holland led to a takeover and SAIT Electronics began trading under the name SAIT-RadioHolland. 1997 brought a merger with another Norwegian company, Stentofon, likewise active in the internal communication systems sector.
