In data centers, museums, archives, and other facilities, the damage caused by a fire can be devastating—not only the value of the equipment itself but also the precious data, historical artifacts, and trade secrets stored within. For these sensitive areas where water or chemical agents are unsuitable for fire suppression, the IG-100 nitrogen fire suppression system offers an environmentally friendly, safe, and efficient solution.
Working Principle: Extinguishing Fire by “Smothering”
Combustion requires three elements: fuel, oxygen, and an ignition source. The fire suppression principle of IG-100 is extremely straightforward—physical suffocation.
Upon system activation, a large volume of high-purity nitrogen is rapidly injected into the protected area, reducing the oxygen concentration from the normal 21% to below 15%. When the oxygen level drops below 15%, most flammable materials will cease burning. Without the oxidizer, the flames naturally extinguish.
This process does not rely on any chemical reactions and does not produce toxic or corrosive byproducts.
Five core advantages
- Absolute environmental protection, zero pollution
Nitrogen is a natural component of the atmosphere, with an ODP (Ozone Depletion Potential) of 0 and a GWP (Global Warming Potential) of 0. After spraying, there is no chemical residue produced, and it has zero burden on the Earth’s environment. - Safe and harmless to human body
IG-100 is non-toxic and harmless, and will not form thick fog when sprayed. Personnel can clearly see the emergency exit. It can also dilute the concentration of toxic gases in the air, help trapped individuals slow down their breathing rate, and reduce the inhalation of harmful substances. Suitable for places where personnel frequently work. - No secondary damage to the equipment
Nitrogen is non-conductive, non corrosive, and residue free. After spraying, it will not cause any damage to precision electronic equipment, cultural relics archives, etc. After extinguishing the fire, there is no need to clean up, and the equipment can immediately resume operation. - The cost of fire extinguishing agents is extremely low
Nitrogen is derived from air, with unlimited sources and low filling costs. The full lifecycle operation and maintenance cost is much lower than other gas fire extinguishing systems. - The fire extinguishing effect is long-lasting and stable
There will be no atomization during spraying, and even if it comes into contact with flames, it will not decompose and produce toxic substances. The system structure is simple and the failure rate is low.
Main application scenarios
The IG-100 nitrogen fire extinguishing system is suitable for extinguishing Class A (solid fire), Class B (liquid fire), Class C (gas fire), and Class E (electrical fire).
Typical applicable locations include:
Data center and computer room
Communication room and base station
Substation and generator room
Museums, Archives, and Libraries
Precision Instrument and Medical Equipment Room
Important documents and treasury
Not applicable scenario: Class D metal fires (such as potassium, sodium, magnesium, etc.), as nitrogen may undergo chemical reactions with these metals at high temperatures.
Main application scenarios
The IG-100 nitrogen fire extinguishing system is an ideal choice for unmanned enclosed space fire protection, especially suitable for:
Places with the highest requirements for environmental protection and personnel safety
Protecting sensitive assets such as precision electronic equipment and cultural relics archives
Pursuing low-cost operation and maintenance solutions throughout the entire lifecycle
When choosing, it is necessary to weigh the advantages of environmental friendliness, safety and harmlessness against the limitations of large space requirements and high sealing requirements, and make decisions based on specific application scenarios.
