It all began in 1927 with the creation by Edgar B Frank of Calorstat, a company specializing in the manufacture of car thermostats.
In 1962, Calorstat and Vernet team up. The year 1965 marks a turning point: we invent the first thermostatic element to use wax. This major innovation disrupts the market and still ensures that today we are World renowned. Since our foundation, we continue our expansion thanks to our 900 employees and our subsidiaries in Argentina, China and the United States.
