15 / 20M High Pressure Mixed Inert Gas Fire Extinguishing System
Introduction to IG541 mixed gas fire extinguishing agent
1. IG541 mixed gas fire extinguishing agent is currently recognized
internationally as a "green" environmentally friendly gas fire
extinguishing agent that can replace halogenated fire extinguishing
agent, and has been widely used internationally. It is a completely
natural combination of nitrogen, argon and carbon dioxide in a
certain proportion (its composition and quality requirements are
shown in the table below). Its ozone depletion potential value
ODP=0 (no damage to the atmospheric ozone layer), greenhouse effect
value DWG=0 (no greenhouse effect), has the characteristics of
colorless, odorless, non-polluting equipment, non-corrosive, and
good insulation performance.
Product advantages
1. Limited underground space: The underground space of urban rail
transit systems is usually very limited, which means that the fire
protection system must be highly effective and occupy less space.
The IG541 gas fire extinguishing system is a fire extinguishing
system that does not require a large amount of water storage or
occupy a large area of space, so it is very suitable for these
limited underground stations.
2. Large flow of people: The rail transit system transports a large
number of passengers every day, and their safety is of paramount
importance. The 1G541 gas fire extinguishing system can quickly
extinguish fires when they break out, reducing the chance of fire
spreading and providing more time for passengers to evacuate. This
helps reduce potential casualties.
