The ALEX system of ENEXIO consists of an aluminium coated steel flat duct.  Aluminium finnings between the flat ducts are hard-soldered to the aluminium coating of the flat duct.  The solder fills the gap between the fin root and the core tube completely to achieve excellent heat transfer properties.

Conventional fin tube bundles need A-supports to carry the weight of tube bundles but the patented ENEXIO self-supporting fin tube bundle with integrated headers needs no support: There are only separation walls and hoist beams needed which results in material savings and a very low erection time.

• Own Heat Exchanger bundle production
• Bundle preassembly at ground level
• Only one small crane needed (1 big lift = 2 bundles)
