Mixed gas(IG-541) Fire Extinguishing System Introduction
Product features:
Extinguishing agent: Does not destroy the ozone layer, it is completely composed of natural gas in the atmosphere — Nitrogen (N2), Argon (Ar), Carbon Dioxide (CO2)
Safe to people, fire-fighting without dense fog
For environmental safety: Ozone depletion potential (ODP = 0), Global warming potential (GWP = 0)
Fire extinguishing agent long transport distance
Applicable object:
Surface fire of wood and fiber materials
Fire caused by the combustion of gasoline, heptane
Gas fire that can be cut off before fire extinguishing
Electrical equipment fire
System composition:
The system is mainly composed of fire extinguishing agent bottle group (including container valve, pressure gauge), pneumatic manual starter, selection valve, one-way valve, safety valve, low leakage high sealing valve, pressure reducing device, signal feedback device, Electromagnetic drive device, driving gas bottle group (including container valve, pressure gauge), nozzle, bottle holder, pipe system and automatic alarm fire control system and other components. According to the project requirements, the use of the above-mentioned equipment can easily form a unit-independent system and a combined distribution system to implement fire protection for single or multiple districts.
Working principle:
Total flooding system
During the specified period of time, a certain concentration of mixed gas is sprayed into the protected area, and it is evenly filled in the protected area. IG541 gas fire extinguishing equipment uses total flooding way to extinguish the fire.
Unit independent system:
Fire extinguishing system with fire extinguishing agent storage device, is for only one protection zone. It is the simplification of the combined distribution system. Apart from the use of a selector valve, the rest of the system is the same as the combined distribution system.
