Product introduction：
HFC-227ea (molecular formula:CF3CHFCF3) isa colorless、tasteless andnon-conducting gas. With the characteristics of clean、low toxicitybut high efficiency, up to now, it is asuccessfully researched & developedfire extinguishing agent and also one of the best products to take the placeofAlkyl halides 1301、1211.
Our HFC-227ea fireextinguishing system,both have trippingtype selector valve and electric control selector valve,whileelectric control selector valve and MasterSlave Actuating CombinedDistributionSystem have obtained the patent of invention. By using a master Slave ActuatingCombined Distribution System( multiple protection zone ) andbased on the type of combustible material, our HFC-227ea concentrationcancanreach the national design specifications in a specified time, thusimplement thefire.
Performance：
1.Fire extinguishing way：
Total flooding extinguishing
2.Extinguishing concentration：
①Fire on solid surface concentration5.8%
②library、Archives and heritage protection zone, concentration10%
③Oil-immersed transformer room , distributionroom with oil switch,concentration 9%
④Power transformer room and distribution room, generatorroom,concentration 8%
3.Injectiontime：
①Power transformer room and distribution room, generator room,≤ 8s
②Other protection zone, ≤ 10s
4.charg pressure and density：
①II Booster welded structures Storage container, Storage pressure4.2Mpa, Maximumcharg density 950Kg/m3
②III Storagecontainer, Storage pressure 5.6Mpa, Maximum charg density1080Kg/m3
5.Safety：
HFC-227ea is less toxicthan Halon 1301, atthe common concentration of 8% it can be used in mostapplications.Thisconcentration is lower than 10.5%, "lowest observedadverse effect level" (LOAEL) to human hearts. While the"LOAEL" of Halon 1301 is7.5% .
6.Ambient temperature：
0℃～50℃
Technical characteristics：
1.The productfunctions in Schematic Diagramof Driving Gas Cylinders Actuating UnitIndependent System、SchematicDiagram of Master Slave Actuating UnitIndependent System、SchematicDiagram of Driving Gas Cylinders Actuating CombinedDistribution System、Master SlaveActuating Combined DistributionSystem
2.Master SlaveActuating uses activecylinders instead of actuation cylinders,thus reduce the intermediate links.The features of micro-motordriving device are: big driving force, smallstarting current, small size, and simplebut beautiful overall structure.
3.The distributiondivice structures ofcombineddistribution system is tripping type selector valve and electriccontrolselector valve. When afire breaks out, it can actute the cylinders of thecorresponding protection zone timely.
Places for Application：
1.Electrical fire;
2.Liquid fire;
3.Fire on solid surface;
4.Gas fire in which gas source can be cutoffbefore extinguishmen.
TheProduct is not applicable to thefollowing situations：
1.Fire of chemical productscontainingperoxides such as nitrocellulose and sodium nitrate, or oxidant;
2.Fire of active metals likepotassium,sodium, magnesium, titanium, zirconium and uranium;
3.Fire of metalhydride like potassiumhydride and sodium hydride;
4.Fire of chemical substances thatdecomposeautomatically such as hydrogenperoxide and hydrazine.
