COTES C35 OPERATING AND SERVICE HANDBOOK page 33/71
In Configuration-C and Configuration-D, the process air fan is equipped with a frequency converter,
which makes dampers on the process air side unnecessary.
The regeneration air should be led to and taken from the outdoors.
The ductwork for the regeneration air should be selected with regard to the external pressure
available from the regeneration air fan and the space available for ducting. A 200mm-diameter duct is
normally recommended for the regeneration air flow.
The regeneration air outlet should be made to drain downwards towards the outlet, to allow any
condensate to run out. If a reduction is needed at the regeneration air outlet, the reducer must be
eccentric enabling condensation being led out throughout the ductwork.
There must be at least 500mm unrestricted access above the dehumidifier for easy access.
If this draining downwards is not possible, drill a ø6mm hole in the lowest part of the duct, so that any
accumulated water can drain away.
NOTE
The regeneration air outlet should be made to drain downwards towards the outlet for
draining.
If this is not possible, drill a ø6mm hole in the lowest part of the duct, so that any
accumulated water can drain away.
