thermal link has been designed to activate at
the standard temperature of 72°C in the event
an elevated temperature within the duct.
link is fitted within a holder, which is screwed
into the case to lock the blade into the desired
position. When set, the locking nut is
'hand-tightened' to secure the cartridge and the
the event of the thermal link being activated,
the integral indicator will extend from the thermal
link cartridge to indicate to the maintenance
engineer that the thermal link has been activated,
with inspection of the system required if deemed
safe to do so.
