5 WASHER-DRYERS
5.1 Drying
system
♦
The drying system is based on forced-air circulation with water-jet condensation. The maximum drying
capacity is equivalent to half the maximum load of dry washing. If a full load is washed, two drying
cycles are necessary. If a half-load is washed, the drying cycle can be programmed for automatic
execution at the end of the washing cycle.
♦
During the drying phases, the drum rotates in alternate directions at low speed. The fan ducts the
heated air from the heating elements to the inside of the tub, where it removes the humidity from the
washing. The cold-water jet, coming into contact with the hot and humid air, generates a heat exchange
and thus condenses the humidity. The cooled, dry air is ducted back to the fan, again heated by the
heating element, and is then circulated back into the drum.
♦
In cycles for SYNTHETIC fibres, only one branch of the heating element is switched on (half power). In
COTTON cycles, both branches are powered (full power).
♦
The cooling water and condensation are drained off by the drain pump.
♦
During the last few minutes of the drying cycle, the heating elements are switched off, while the fan
continues to operate in order to complete the cooling phase.
