Experience and passion since 1981

D.B.M. S.p.A. was founded in 1981 and has become one of Europe’s top manufacturers of finned-pack heat exchangers.

From our first plant in Varallo Pombia (Novara), we’ve grown steadily thanks to investments in research, people, and production technologies.
In the 1990s, we opened GeoCoil in Artegna (Udine), expanding capacity and reaching more international markets.
In 2004, the Bertolo family took full ownership of DBM and GeoCoil, focusing on growth through innovation, quality, and customer service.
Today, DBM continues to invest in technology, R&D, and training, becoming a trusted partner for major HVAC OEMs and industrial clients in over 30 countries.
