waterfin® is the designation of ALUCOAT for the lacquered foil intended to be used for the production of fins for heat exchangers with hydrophilic properties. The lacquered aluminium coils waterfin® makes the condensated water drop to become a layer avoiding the feasibility of ice bridges. It allows to produce smaller equipments.
Its mains advantages are:
There are two kinds of lacquered aluminium coils of waterfin®:
ALUCOAT supplies its product waterfin® in reels of wide until 1.600 mm, with core of steel or carton of up to 500 mm and maximum weight of 6 tonnes. It can be used for the development of the following applications:
Aluminium foil from 100 to 300 μm with silica based or silica free lacquer for both sides.
