IG-100 uses Nitrogen for a clean, safe and 100% ecological extinguishment. This gas is widely used in a variety of extinguishing systems due to its excellent pressurization conditions.

In this case it complies with equal smothering efficiency by reducing the oxygen concentration to extinguish the fire, while leaving a percentage of oxygen suitable for occupied areas. Due to this feature, hazards can be protected where there is the possibility that people will be in the enclosure at the time of the fire, ensuring their safe evacuation both in terms of the level of oxygen in the room, and the absence of chemicals in the discharge. In addition, its physical and dispersion properties help maintain visibility during the evacuation.

It is highly recommended for class A, B and C hazards. The system operates by total flooding of the room, ensuring discharge in less than 1 minute with the safety conditions mentioned above. Gielle has two variants depending on the storage pressure: IG-100 at 200 bar and IG-100 at 300 bar; this makes it possible to adapt the quantity of extinguishing agent required, to the storage space available for the cylinders.

The system is optimized for the worst case conditions, all components are certified to ensure the strictest performance. These are necessary for the storage, detection, release and discharge of the agent at the right moment.

About IG 100 extinguishing agent

Nitrogen gas is clean, generates no combustion products, is non-toxic, and does not cause irritation to the skin and eyes. It is harmless to people at design concentrations and is therefore ideal for extinguishing fires in occupied spaces. In addition, when discharge occurs, visibility is high, so that evacuation is not impaired.

Pure nitrogen is obtained by distillation of air, so it is a completely environmentally friendly gas with zero ozone depletion (ODP) and zero global warming potential (GWP). Since it is not a mixture of gases, it is easy to refill and can be acquired at any geographic location.

Nitrogen is non-corrosive and can be used at normal temperatures with materials typically used in industry and construction. It is electrically non-conductive and is therefore highly recommended for protecting electrical and electronic materials. Colorless, odorless, tasteless, electrically non-conductive and chemically neutral gas.



Inert Gas IG-100 is a clean agent fire extinguishing system using an inert gas (IG-100) consisting of 100% Nitrogen and is used in total flooding systems. Inert Gas has become widely accepted as the best performing, cost effective, and environmentally friendly inert gas fire extinguishing agent, offering extended hold times and great flexibility in design.

The patented pressure regulating discharge valve used in the Inert Gas system utilises a superior valve design to automatically regulate the pressure of the extinguishant at discharge, providing an ideal discharge pressure and maintaining a constant flow rate throughout the discharge.

Zero Ozone Depletion Potential (ODP)
We simply borrow Nitrogen and Argon from nature. When released, they automatically return to their natural place in the environment.

Zero Global Warming Potential (GWP)
Nitrogen and Argon have no atmospheric lifetime and zero GWP, so they pose no risk to the environment.

Weight Similar To Air
The weight of inert gas agents corresponds closely to that of normal air and will evacuate a protected area slower than halocarbon agents after a discharge.

No Combustion By-Products
Inert gasses do not decompose into toxic or corrosive elements in a fire, making it a safe choice for people and assets.

No Fogging
inert gas systems is ideal for occupied spaces because escape routes remain visible during, and after a discharge.

No Residue
That means no damage to your equipment and no clean up required

Electrically Non-conductive
It is electrically non-conductive and is therefore highly recommended for protecting electrical and electronic materials.

Minimal Thermal Shock
When discharged, inert gasses cause the least amount of thermal shock (sudden temperature drop), compared to other clean agents.
