Life-safety dampers are critical fire-protection features of buildings. By protecting duct and air-transfer-opening penetrations through fire- and smoke-rated construction, they help to contain fire ...

Series ZCD zone control dampers are designed to meet the demand for zone-specific products combined with individual controls. Model ZCDRS25 can be installed in existing round duct. It comes with 24-V ...

Pneumatic furnace damper drives may be more common, but electro-hydraulic actuators provide several advantages to the more traditional control scheme. One fossil-fired plant in Taiwan achieved more ...

An algorithm has been developed for the control of semi-active dampers which uses the feedback of displacement and velocity signals measured across the damper. This algorithm has been called "relative ...

The main objective of this project is to develop and test a phased damping device, or “gap damper”, to act alongside a base isolation system for buildings or bridges. The gap damper provides ...
