Spring Return Electric Actuators Meet Fire Standards for Tunnels
with mechanical springs that close (or open) the damper upon loss of power at the actuator. Further, the motorized dampers must function at elevated temperatures to be effective. The ProMation PA series of spring return quarter turn, fail-safe electric actuators successfully performed a high temperature
Electric Spring Return Actuators Meet Fire Standards for Tunnels
In an emergency situation such a fire inside a tunnel, 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.
