Heat Activated Dampers

As the name suggests a heat activated damper automatically operates during an ‘over-temperature’ situation. Usually the damper is arranged in such a way to be held open by a fusible link against the torque provided by a rotary spring or counterweight. When the heat-activated link breaks the damper closes quickly. Several types of fusible links are available using a variety of alloys with particular melting points.
