A story that began in 1960

RADIATORS, formerly known as TROPIC, was founded in 1960 in Moimacco (UD) and specialised in the manufacture of oil-filled lamellar radiators. In the 1980s the company was acquired by the De’ Longhi Group, which launched an investment plan that included the installation of new steel-panel production lines. In 2000, with the acquisition of Sile Corpi Scaldanti, a Venetian company specialising in the manufacture of designer radiators, DL Radiators began a process of growth in the European markets and in different sales channels, therefore establishing itself as a point of reference in the heating market.

By introducing 4 production lines in 2006 that use sophisticated technology to produce multi-column radiators and by adding production lines in 2008 dedicated to the production of electric aluminium radiators, the company has completed its range of products that respond to the multiple needs of the market and has become the largest radiator manufacturing company in Italy.
