ravenscroft logoHealthier Air - Energy Saving

Ravenscroft specialises in providing innovative and energy efficient engineering solutions for the heating and ventilating sector. Our customised engineering solutions yield high quality indoor air while reducing HVAC operating costs.  

damper-_halton_ravenscroft_hfbThe Halton HFB is a variable airflow damper and contains an averaging airflow measurement probe, airflow controller and actuator.

Airflow is controlled based on actual flow measurement by changing the damper blade position. The airflow setpoint can be modified between factory-set minimum and maximum settings by, e.g., a room controller with an analogue signal (0...10 or 2...10 VDC). Flow control damper HFB maintains the required airflow independent of duct pressure variation.

The static pressure control damper option maintains the desired.
