Aluminium and aluminium with epoxy coating.

The Heatex Model T exchanger is characterised by the fact that the plates, made of raw or epoxy coated aluminium, are corrugated.

Heat transfer is improved by the surface creating turbulence. The special plate design combined with the increased efficiency of a two-step arrangement, along with the benefit of a compact casing, makes Model T to a preferable choice for many applications. The fact that the Model T is made fully out of aluminium makes it better withstand winter conditions, which assures a longer life time.
