3S is made up of three production units: the first is based in Cambiago (Milan), where there is the warehouse for the storage of raw materials and the production department. The finning processes of the tubes, the construction and assembly of heat exchange coils with finned tubes, and finally the construction of shell and tube heat exchangers are carried out there.
The second production unit is in Trezzano Rosa (Milan), where the finned block heat exchange coils are designed and built. Our executive and administrative offices and an avant-garde technical design office that works with the most modern technologies and 2D and 3D CAD design-prototyping systems are also located here.
