Gas fire extinguishing system is four traditional fixed fire extinguishing systems (water, gas, foam, dry powder), one of which is a gas fire extinguishing equipment (or component) composition and alarm control system. Typical applications for gas extinguishing systems or objects: 1. electrical and electronic equipment 2. Communication Equipment 3. flammable and combustible liquids and gases 4. Other high value of the property and an important place for (parts of) gas fire extinguishing system has the Heptafluoropropane, IG541 mixed gas, CO2 gas, S four gases aerosol fire extinguishing system, heptafluoropropane, IG541 mixed gas, S-type aerosol fire-extinguishing systems are all total flooding fire extinguishing system, CO2 gas total flooding fire extinguishing system in addition to the way the outside but also local application . . S-type aerosol fire extinguishing principle of a human body without harm: the discharge of S-type aerosol fire extinguishing agent whose main component is N2, a small amount of CO2, salts and other solid particles, are non-toxic substances. The actual fire, S-type aerosol fire blowdown process only about 1 minute to complete the extinguishing time is only 2-3 minutes, the process of the human body without harm. . b extinguishing high efficiency, no secondary damage to the appliance: S form of aerosol fire extinguishing mechanism is the heat to cool the fire, chemical suppression fire, so the high extinguishing efficiency. S aerosol decomposition products strontium (Sr) salt aerosol, which primary oxidant strontium nitrate SrO, Sr (OH) 2, SrCO3, these three substances will not absorb moisture from the air, and thus will not form a conductivity and corrosive electrolyte film, thus avoiding damage to the equipment. K, S-type fire extinguishing agent attachment surface resistance requirements are not less than 1MΩ and 20MΩ (10MΩ above an insulator). c extinguisher with less: Aerosol extinguishing agent is generally used in an amount of about 130g / m3, while the other gas fire extinguishing agent was 300-1000g / m3, such as:. HFC-227ea as 530g / m3 d save weight and space: Aerosol Because it is a solid pressure extinguishing system storage, greatly reducing the volume and weight of its weight is only 1/40 of an inert gas, the space occupied by only its 1/15 e environmentally friendly: aerosol fire extinguishing agent free of atmospheric ozone damage substance that ODP, GWP value of zero, is the ideal alternative to halon f easy installation, low maintenance costs: aerosol fire-extinguishing systems and other gas installation compared to only some of the connecting wires to install, the installation is extremely easy and convenient, can save time and 1/3. Since no pressure vessels, valves, nozzles and other maintenance is very low. . g Cost savings: Because aerosol fire-extinguishing system light weight, small footprint, simple installation, pressure storage and negligible maintenance costs, it has the lowest cost in gas fire products.
