4.6.5 Ductwork for wet air outlet
The wet air duct must be made of plastic or another corrosion resistant material. It must be able to handle
temperatures between -30 °C and 75 °C, be no more than 1.5 metres long and be insulated to prevent ice
formation. This also applies to the part of the duct passing through the wall.
Because of its high moisture content the wet air leaving the dehumidifier will condense on the inside of
the duct walls. Due to the low ambient temperature there is a risk of ice formation. The wet air duct must
therefore be insulated.
■
Horizontal ducts must be installed with a slight decline (away from the dehumidifier) to drain away
possible condensation. The decline must be at least 2 cm/m of duct.
■
5 mm drain holes should be made at low points of the duct to prevent water accumulation in the duct.
■
To prevent the outgoing wet air from humidifying the incoming reactivation air, the wet air outlet must
be placed at least 2 metres from the reactivation inlet. See
.
NOTE!
Always drill the drain holes on the outside of the cold storage/freezer room wall.

ARNING!
The wet air outlet is hot. To avoid burns from unintended contact, make sure it is insulated.
