This Duro Dyne ML-165 Fusible Link is an indispensable safety device for commercial and industrial HVAC systems, particularly where fire and smoke dampers are installed. Its primary purpose is to provide a thermal release mechanism, ensuring that dampers close automatically when exposed to elevated temperatures during a fire event.
HVAC contractors and fire safety professionals rely on these links to comply with building codes and enhance occupant safety. The 1-1/2 inch bearing length indicates its specific application for certain damper mechanisms, making precise selection crucial for proper function and compliance.
When replacing or installing fire dampers, verifying the correct fusible link model, such as the ML-165, is paramount. This component acts as a critical failsafe, melting at a predetermined temperature to allow the damper to spring shut, thereby compartmentalizing fire and smoke within the building.
