What are Motorized Dampers?
At the most basic level, a damper is an adjustable plate, or assembly of plates (also called blades), used to control or to alternately block and allow a draft or an airflow. Motorized dampers are dampers whose blades are opened, closed or adjusted to an intermediate position through the application of power from a motor. One common application of motorized dampers is in a zoned air conditioning system. The motorized dampers, positioned in ducts leading to each zone, would be controlled electronically. By alternately closing or opening a given motorized damper, or by leaving a damper in an intermediate position, different zones could be maintained at distinct selected temperatures. Motorized dampers are also necessary in applications where flows of combustible or otherwise dangerous gases need to opened and closed automatically based on signals from detection equipment. Or, dampers may be selected to be motorized for ease of operation. Motorized dampers are often spring controlled. The
