Tesio Radiatori was born in Turin at the beginning of the last century as a manufacturer of radiators for the automotive industry and has followed its growth over the years.
It joined the Chausson Group, took on the technical know-how and became one of the first Italian companies in special industrial applications.
Tesio Radiatori ended his experience in the Chausson-Valeo Group, still maintaining excellent relationships with the companies that joined the Valeo Group.
In this decade the company specialized in the production of complete cooling systems for transformers and in the production of water radiators, oil exchangers, air-air exchangers (aftercooler). Applications are concentrated in the railway, agricultural, earthmoving and industrial machinery sectors.
Tesio Radiatori was acquired by the T.RAD Co Ltd. Group, a Japanese multinational leader in the sector, gaining an international projection. In 2005 it changed its corporate name to T. Rad Italia Spa.
it returns to being an independent company taking up its original name Tesio Cooling Systems. It accentuates the focus on the design and production of complete cooling systems for the railway sector made with vacuum braze-welding Plate and Bar technology.
Tesio Cooling Systems joined the Telema Group a highly specialized international player in the design and construction of the entire range of Thermal products, for the Railway and Off-Road Vehicle sectors.
