From an old sugar beet distillery founded in 1881 with a rail spur still in operation, the plant was purchased in 1900 by William Augereau, resident engineer in Pons, owner of the Castle of Riddles, who set up a factory mounting on safety in railways.

In 1918, the Company and Westinghouse brake signals and establishes, as part of its decentralization a plant material intended to equip the French railways. The plant in Pons is dedicated to the construction of  material to transfer steam. This activity engineering is maintained until the beginning of World War II.

In 1940, the plant was ravaged in part by fire, but was quickly rebuilt to continue its industrial activity until 1948. Through his professional experience largely acquired in the field of steam, the company diversifies its production then extending to heaters for industrial and domestic sectors.
