    Motorized Exhaust Dampers

    MED-HP

    Motorized exhaust damper for High Pressure.

     icons

    A motor-controlled flue gas damper is suitable for installation in the exhaust systems for all standard appliances which are fired with oil or natural gas. During standstill periods of the appliance, the damper (flap) automatically closes the exhaust path preventing loss of heat. When the temperature controller needs heat, the electric motor automatically opens the shut-off flap before the burner starts and the program of the burner control unit is enabled.
