HEAT CONCEPT, 100 years of technological evolution in heat treatment

Since 1972 thanks to its ” ELTI ” brand and since 1922 through its ” Fours et Brûleurs REY ” (furnaces and burners REY) brand.The creation of the company REY dates back to 1922. Originally located in Alsace, its vocation was to make industrial gas burners and furnaces. Pushed along by international events, Edouard REY decided to be closer to his clients in 1943 by settling in Saint-Etienne (42 – France). In the 1960s, his son Jean-Paul REY developed heat treatment processes, more specifically the heat treatment of metals.

In 1978 the arrival of Jean Jacques REY, the third generation, marks the creation of the climate engineering section. In 2011, with the desire to develop further the climate enginerring department, the company decided to sell the ” Fours et Brûleurs REY ” brand.

Thus, the company ELTI, a fellow member recognized for its experience and skills in the manufacturing of electrically heated furnaces, decided to extend its offer by acquiring it. This takeover ensured the historical customers of the company REY, a continuity of services and allowed ELTI to diversify itself by being positioned on the market of gas ovens.

The company ELTI (Ets Loire Thermie Industrielle) was founded in Saint-Chamond (42 – France) in 1972 by Dr Oddino DORIGO, an Italian industrialist Doctor of Metallurgy.

Already manufacturer of industrial furnaces in Italy, he decided at the beginning of the 1970s to move and manufactured some of his products in France. Among his contacts, Antoine PINAY, Mayor of Saint-Chamond, and incidentally ex-President of the Council at the national level, invited him to set up his new factory in his town.

ELTI will first carry out realizations under license from the Italian company. Then, quite quickly, it set up its sales department and open its Design Office in order to design its own furnaces, in particular to answer the expectations of the French market.

Opening up to export from the early 90s will allow the ELTI brand to gain recognition beyond national borders.
