Non-pressure fixed & suspension type superfine powder extinguishing device Product introduction
Non-pressure fixed & suspension type super fine powder extinguishing device series product adopt solid gas conversion principle. When gas-solid reaction be activated to produce a large number of gas to drive superfine powder jet from device nozzle in high-speed. It adopt ABC superfine powder extinguishing agent, fire extinguishing efficiency is high.
This series products can be used for airtight space to realize totally flooding fire extinguishing. It can also be used for open places partial area fire extinguishing.Scope of application
Applies to extinguish fires in A, B, C and D classes.
Such as production workshop, office, document storage room.
Combustible liquid, combustible solid warehouse.
Store, generator room, power distribution room, cable ditch and other places
As well as train, ship and other means of transport.Not applicable scope
Nitration, explosive and other oxygen free energy is still fast oxidation of the burning of chemical substances.
Strong oxidizing agents such as sodium, potassium, zirconium, titanium and other active metal fire.
The depth of the smoldering fire.
Explosion dangerous place.
Crowded places.Working principle
When the superfine powder fire extinguishing device receives the start signal, and electric current start the trigger component to ignite gas generator agent to generate a lot of gas. As the pressure inside the tank is rapidly increasing, the superfine powder will rush out by the gas driven force and break the seal diaphragm , and jet & spread cover very quickly to the protecting area. Totally flooded by superfind powder type fire extinguishing state. Or partial flooded by superfine powder type fire extinguishering state. Fire flame will be extinguished under the superfine powder's continuous physical & chemical action. Technical parameters
