Intelligent fire extinguishing device-perfluorohexanone

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.

III. Existing types and specifications
? ??Customizable as per customer's requirement.
