The rack mounted fire extinguishing system is pre-integrated in the cabinet.
The extinguishant is perfluorohexanone which features high insulation,
environment friendly, and quick fire extinguishing and cooling.
When the temperature inside the cabinet is higher than the temperature of
the thermo bulb for a certain period of time, the thermo bulb breaks to start
the rack mounted fire extinguishing system.
When the external fire suppression system detects a fire, it triggers the
electric start signal of the rack mounted fire suppression system and opens
the storage device of the extinguishant. The extinguishant is released through
the nozzle to cool down and put out the fire.
NO TE
● The thermo bulb can also work normally during electric startup.
● When a fire occurs, the thermo bulb can start the rack mounted fire extinguishing
system even if the electric startup mode fails. This ensures that the rack mounted fire
extinguishing system can be started reliably.
