Brief introduction of IG100 gas fire extinguishing agent
IG100 gas fire extinguishing agent is recognized as a "green"
environmental protection gas fire extinguishing agent which can
replace halon fire extinguishing agent in the world, and has been
widely used in the world. It is composed of nitrogen medium (see
the table below for its composition and quality requirements), and
its ozone depletion potential value ODP=0 (no damage to the
atmospheric ozone layer) and greenhouse effect value DWG=0 (no
greenhouse effect). It is colorless, odorless, non-polluting,
non-corrosive and has good insulation performance. After the fire
extinguishing agent is sprayed into the protected area, the oxygen
concentration decreases and the carbon dioxide concentration in the
protected area increases. The moderate increase of carbon dioxide
concentration can accelerate people's breathing frequency, improve
their oxygen absorption function, and maintain their oxygen
absorption needs to some extent. IG100 fire extinguishing agent is
stored and sprayed in gaseous form. When it is released to the
high-temperature protection zone where a fire occurs, it will not
decompose, produce toxic decomposition products, form dense fog or
cause unclear vision, so as to ensure that people can clearly see
the emergency exit when they escape. Therefore, IG100 gas fire
extinguishing agent is non-toxic and harmless to human body, and it
is a safe and environment-friendly gas fire extinguishing agent,
which is suitable for places where people often work.
IG100 gas composition and quality requirements
| Main components | Nitrogen(N2) |
| Proportion | 100% |
| Purity requirement (volume ratio) | ≥99.9% |
| Water content requirement (mass ratio) | ≤4×10-4% |
| Oxygen content requirement (mass ratio) | ≤3×10-4% |
Fire extinguishing principle of IG100 fire extinguishing agent
As we all know, a substance needs to have three elements to
maintain combustion: ① it should be combustible, ② it needs an
accelerant (oxygen), and ③ it needs to reach a certain temperature.
Usually, the oxygen concentration in the protection zone is about
21%. If the oxygen concentration in the protection zone is reduced
and the oxygen content in the air is reduced, the reduction of
oxygen content in combustible materials can reduce the heat
generation rate during combustion, and when the heat generation
rate is reduced below the heat loss rate, the combustion will stop.
Experiments show that when the oxygen concentration in the
environment drops below 12.5%, most combustible materials will stop
burning. When a fire occurs, IG100 gas can be sprayed into the
protection zone, so that the oxygen in it can be reduced to below
12.5%, and the combustion products can be stopped, thus putting out
the fire.

2. System composition The IG100 gas fire extinguishing equipment
provided by our company adopts total flooding fire extinguishing
method, which can usually be divided into the following two forms:
(1) Unit independent IG100 fire extinguishing system (Figure 1): A
set of IG100 fire extinguishing agent storage device corresponds to
a set of pipe network system to protect a protected area. (2)
Combined distribution type IG100 fire extinguishing system (Figure
2): A common IG100 fire extinguishing agent storage device
corresponds to several casing network systems to protect multiple
protection zones.
1. Fire extinguishing agent bottle bracket. 2. Fire extinguishing
agent bottle group. 3. Connect the pipes. 4. Fire extinguishing
agent circulation pipeline one-way valve. 5. Safety release device.
6. Collecting pipe. 7. Control the trachea. 8. Signal feedback
