Inert Gas Fire Suppression Systems
The idea behind inert gas extinguishing systems is to put out a fire by lowering the oxygen concentration in the protected area. These systems use argon, nitrogen, and their mixtures as extinguishers. Inert extinguishing gas is discharged into the protected space in such a way that the oxygen concentration is reduced to the point where combustion cannot occur, and the fire is extinguished. Every system is developed to meet these requirements in less than 60 seconds.
Since the gases argon and nitrogen used in inert gas extinguishing systems are already present in the atmosphere, they have no global warming effect and have no potential to harm the ozone layer. They are non-conductive, odorless, and colorless extinguishers that, at ambient temperature, do not corrode substances like plastic, steel, copper, brass, nickel, or stainless steel.

Inert gases have higher tightness tolerances than chemical clean gas extinguishers because, due to their weight close to air, they exit the protected space more slowly. They do not produce toxic residues during a fire and only slightly produce fog, making them perfect for use in manned areas.
One benefit of inert gas systems is that they can be used to protect distant locations due to their high pressure. These systems can be made up of single and multi-cylinder sets and can be stored in 150, 200, and 300-bar cylinders. Another benefit is that diverter valves allow multiple spaces to be protected by a single set of cylinders. It also means that buildings with distinct units can be extinguished from a single center with the use of a minimal cylinder area.
There are several types of inert gas extinguishing systems available:
- IG01 – 100% Argon
- IG100 – 100% Nitrogen
- IG55 – 50% Argon + 50% Nitrogen
- IG541- 52% Nitrogen + 40% Argon + 8% CO2
In the final result, inert gases;
- It is colorless, odorless, and non-conductive.
- Has no negative effects on the ozone.
- It has no effect on global warming.
- It can be used in manned spaces safely.
- Can be used to replace Halon 1301 systems.
- It is stored in 150, 200, and 300 bar cylinders and has an installation pressure of 55-60 bar.
- ISO 1450, UNE 23570, and NFPA 2001 are the assembly and design standards.
- Easy and common to fill,
- By using diverting valves, multiple locations can be protected from the same center.
- The discharge time for Class A surface fires is 60 seconds,
- One or more cylinders can be used,
