Dampers are controlled by an electric modulating actuator, connected to a volumetric control system. The control system enables a user to set the required flow rate, with specified upper and lower threshold values.

Intelligent dampers can be supplied factory set to customer requirements, supplied with a flow test certificate of conformity.
