Energy Storage Fire Fighting Nozzle
Nozzles for hanging fire extinguishing devices
The suspended perfluorohexanone fire extinguishing device is also one of the pipe-free gas fire extinguishing devices. It is a prefabricated fire extinguishing system that stores the designed fire extinguishing agent in a gas bottle, is equipped with a nozzle, an electromagnetic drive device, and a signal feedback device, and is installed in a suspended manner. It is suitable for small protection areas such as power distribution rooms, transformer rooms, instrument and equipment rooms, small oil depots, computer rooms, software libraries, communication rooms, archives rooms, and file management rooms.
Suspended, small-capacity fire extinguishing devices are pre-assembled storage containers, container valves, sprinklers, etc. into independent, hangable gas fire extinguishing devices. This device has the characteristics of flexible layout, fast fire extinguishing speed, high safety factor and stable operation. Our company designs and produces various types of customized atomizing nozzles for suspended and small-capacity fire extinguishing devices.

Applications of sprinkler heads for suspended fire extinguishing devices:
Suspended fire extinguishing device nozzles have a wide range of applications and can extinguish Class A solid, Class B liquid, Class C gas, and Class E live equipment fires.
It can be used in libraries, archives, treasure warehouses, computer rooms, telecommunications centers, communication rooms, testing centers, medical precision instrument rooms, etc. It can also be used in power distribution rooms, power supply rooms, oil depots, oil storage rooms, power transformation and distribution rooms, electrical aging rooms, spray painting lines, spray paint rooms, automobile garages, ship cabins, chemical flammable products warehouses, impregnation oil tanks and other places.
Principle of hanging perfluorohexanone fire extinguishing device:
1. Cool down and extinguish fire: After the perfluorohexanone liquid is atomized and sprayed at high speed, it vaporizes when exposed to heat. Due to its large vaporization heat capacity and strong heat absorption ability, the flame quickly loses heat and destroys the tetrahedral balance of the fire.
2. Suffocation fire extinguishing: Perfluorohexanone has a large specific gravity. During the process of suspension and falling, it can isolate oxygen in the air around the flame.
3. Chemical suppression and fire extinguishing: It can capture the free radicals of the combustion chain reaction and terminate the chain reaction of flame propagation.
