A DST DC-10 dehumidifier is installed against the wall. Spiral channels distribute the dry air evenly in the loft space. The humidistat is set at required RH value. Cordless logger with warning lamp is installed and emits an alarm if the RH in the loft exceeds the pre-set value. It also regulates the dehumidifier so it’s only turned on when needed, this saves a lot of energy.
