Electric Spring Return Actuators Meet Fire Standards for Tunnels

In an emergency situation such a fire inside rail or road tunnels, or even underground passenger platforms, electric motor operated dampers in the ventilation system can act to clear smoke from the structure as well as to suppress spreading of the fire. Most electric actuators that operate these dampers are required to be failsafe". They are equipped with mechanical springs that open (or close)...

Greenheck ICD Dampers Earn AMCA Efficiency Rating

Greenheck’s ICD series of Insulated Control Dampers have earned AMCA’s new certified rating of Energy Efficiency. This new test method, which is found in ANSI/AMCA standard 500D-12, assigns a damper a Thermal Efficiency Ratio (E) by comparing its thermal performance with the thermal performance of a standard reference damper. In addition to being certified for energy efficiency, the...
