Perfluorohexanone fire extinguishing equipment for power distribution cabinets

I. Principles of fire extinguishing
    It is mainly to extinguish the fire by removing most of the heat from the fire scene, i.e.: after the release of perfluorohexanone fire extinguishing agent, it forms a gaseous mixture with the carrier gas N2, which is very easy to absorb or consume a large amount of heat, so as to extinguish the flame temperature quickly and realize efficient fire extinguishing.

II. Main advantages
1, good environmental performance: green environmental protection gas;
2、High fire extinguishing efficiency: low fire extinguishing concentration can quickly extinguish the fire;
3. Safety in use: no cases of low toxicity have been observed;
4, good electrical insulation properties: ordinary wire and cable does not cause damage to the insulator;
5, fast cooling effect: fire extinguishing agent sprayed with a unique cooling effect;
6, extinguish the fire without residue: in the use of rapid evaporation, will not cause damage to precision instruments, antique paintings and calligraphy;
7, atmospheric storage and transportation without worry: liquid at room temperature, can be transported as ordinary goods, easy to fill, transportation and storage;
8, can extinguish electrical fires, solid surface fires, liquid fires and gas fires that can cut off the gas source before extinguishing.
