GH Dehumidifiers for radiant cooling system
To allow the correct functioning of the dehumidifiers, it’s important to grant a constant air flow to the unit. This flow
must be close to the nominal value (see the drawing). The maximum tolerance allowed is 20%. .
The installer will take care to verify, during the start-up, the air flow to the unit and modify, if necessary, the speed
of the fans.

If the air speed through the evaporating coil exceed the 1,5÷2 m/s, the dehumidification capacity of the unit is stron-
gly reduced and the required environmental conditions can be compromised.
