I. Principles of fire extinguishing<\/strong>
Primarily a physical fire extinguishing effect:
1, so that the protected area cooling, fire extinguishing agent dispersion, consumption of oxygen, to achieve the effect of fire prevention;
2. Heptafluoropropane fire extinguishing agent is sprayed in liquid form to the protected area. In the nozzle, the liquid fire extinguishing agent quickly enters into the gas that needs to absorb a lot of heat and reduces the temperature around the protected area and the flame;
3, Heptafluoropropane fire extinguishing agent consists of large molecules, when the fire molecules in a part of the key fracture needs to absorb heat;
4. The presence of extinguishing agents and flames in the protected area reduces the concentration of oxygen, thus reducing the rate of combustion.<\/p>
II. Main advantages<\/strong>
\u00a0\u00a0\u00a0 Colorless, odorless, non-conductive, non-corrosive, no environmental restrictions, shorter atmospheric retention period. Its non-toxic reaction (NOAEL) concentration of 9%, toxic reaction (LOAEL) concentration of 10.5%, and its design concentration is generally less than 10%, which is safe for human body. It is characterized by good cleanliness (completely vaporized in the atmosphere without residue), good gas-phase electrical insulation and good physical properties suitable for use in fire extinguishing systems.
III. Existing types and specifications<\/strong>
1\u3001Type: tube network type, no tube network type (cabinet type: single bottle, double bottle).
2. Specifications:
There are mainly 70L, 90L, 120L, 150L and other series of specifications and models, which can be customized.<\/p>
