Hot water coil (external)
The hot water coils are supplied in a dedicated section to be installed in the supply air flow line. The casing has the same sizes and features of the main unit and it is fixed with a dedicated installation kit supplied with it. The coil is manufactured with copper pipes thickness 0,4 mm and aluminium fins thickness 0,11 mm. The pipes are mechanically expanded in the aluminium fins to increase the thermal exchange rate. On request, it is possible to install coils with different capacities from the standard ones, when previously agreed with the factory.
