For GOLD air handling units with RECOsorptic heat exchangers, humidity may be recovered and controlled using optional humidity sensors and functions included as standard with the built in controller. Controlling the speed of the heat exchanger, taking into account the humidity of the building and the outdoor air, allows the optimization of humidity recovery.

In the winter, a drying function can be activated to avoid temporary high humidity indoors.

Sometimes extra humidity needs to be added to the room to maintain a good indoor climate. The GOLD air handling unit controller also has built-in functionality to control an evaporative humidifier or to control a steam humidifier. Depending on the location of the humidity sensor, the humidity can be controlled in the supply air, extract air or in the zone served. A weekly timer with four time channels makes it possible to switch between two configurable values (%RH). If a steam humidifier is installed and it’s equipped with an electricity meter, the energy consumption can be reported in the GOLD air handling unit’s hand-held terminal and built-in web page.
