The company ELMA (ELectro-Mécanique de l'Aveyron), owned by the French group Labinal, introduces the first retarder in collaboration with Mr Raoul SARAZIN, who grants exclusive use of his patents to ELMA in 1949. Electro Mécanique de l’Aveyron changes its name to Compagnie TELMA in 1954.
Telma introduces RIC technology, which allows for an improvement of the braking torque by approximately 10%, with no impact on power consumption or the weight of the retarder.
