Presentation of our Inert Fire Suppression Systems available at 200 bar and 300 bar. All 4 types of gases offered: Argon (IG-01), Nitrogen (IG-100), IG-55 and IG-541

1. Comparison of Agents
- Inerts

2. To better understand how the different agents offered by AIRFIRE WORLDWIDE extinguish a fire, a quick review of the principal
aspects of fire chemistry is given below:
Four components– fuel, oxygen, heat and the combustion chain reaction – form the well known Fire Tetrahedron (also known as
the Fire Triangle in the simplified version).
All four of these factors are necessary in the right mixture for a fire to ignite and continue burning. Removing or changing the balance
between any of these factors extinguishes the fire:
• By interrupting the combustion chain reaction, means by which Chemical Agents extinguish.
• By containing or eliminating the source of fuel, currently there is no agent which uses this mean of suppression.
• By cutting off or diluting the source of oxygen, main mechanism used by Inert gases
• By removing sufficient heat from the fire, main mechanism used by Chemical Agents and Carbon dioxide

3. All Inert gases are eco-friendly:
• no ozone depletion potential,
• no greenhouse effect potential,
• non-toxic,
• no residues upon discharge.
The Inert gases available are:
IG-01 // Argon
IG-100 // Nitrogen
IG-55 // Blend, 50% Nitrogen – 50% Argon
IG-541 // Blend, 52% Nitrogen – 40% Argon –
8% Carbon dioxide
They are stored in high pressure cylinders which can be filled at 200
and 300 bar at 15 ºC.
Upon detection of a fire the inert systems discharge automatically
and extinguish within 60 seconds (compulsory by International
Standards).
The main extinguishing mechanism of Inert gases is by cutting off
or diluting the source of oxygen reducing its concentration to
below 15%.

4. ADVANTAGES
- No depletion of the ozone layer, Montreal Protocol.
- No greenhouse effect (no climate change), Kyoto Protocol.
- Easily refilled locally.
- Non conductive electrically.
- Safe for humans, hence no special safety devices have to be
considered.
- Due to its high pressure, the cylinder location is not limited
to a maximum distance from the protected risk.
- Can be configured to protect various risks with only one
system.
- Visibility is not reduced upon discharge.
- Ability to reach hidden fires
- No residues created or left after discharge, making clean up
quick and easy.

5. 1) Fire activates detection system
3) Gas pressure is reduced from 200/ 300 bar to
60 bar via a calibrated restrictor in the
manifold
2) Signal is sent to the control panel which in
turn activates the suppression system

through nozzles, extinguishing fire in 60s

6. AIRFIRE WORLDWIDE SYSTEM CONFIGURATION
Our Inert systems can be configured in different ways depending on the volume of the hazard to protect. Typical setups are:
- Modular cylinder (one cylinder set up)
- Bank system (multiple cylinder set up)
If several hazards have to be protected, one bank system can be used along with selector valves.
Components of the System
All our systems include the necessary components to be installed easily and quickly:
- High pressure cylinder (filled with required Inert gas)
- Discharge valve
- Pneumatic/ manual activation
- Hoses
- Manifold
- Cylinder brackets
- Nozzles (with calibrated diaphragm)
Only the necessary piping has to be added.
