Inert Gas Fire Suppression Systems

The IG-01 Argon gas fire suppression system is an inert gas fire extinguishing solution defined under TS EN 14005, ISO 14520, and NFPA 2001 standards. It is widely used for protecting high-value and sensitive environments such as archives, museums, libraries, storage facilities, and technical rooms with large volumes.

Argon is a naturally occurring, non-conductive, and chemically inert gas, making it a highly reliable clean agent for fire protection applications.

Working Principle

The IG-01 system extinguishes fire by reducing oxygen concentration in the protected area to approximately 15%, which is below the level required to sustain combustion.

The system is engineered to achieve the required extinguishing concentration within a maximum of 60 seconds, ensuring fast and effective fire suppression.

System Design and Operation

IG-01 systems are designed using VdS-approved hydraulic calculation software, ensuring accurate flow and distribution.

• Multiple hazard areas can be protected using a single cylinder bank with selector valves
• Cylinders are monitored using low-pressure switches for continuous gas level supervision
• All components comply with TS ISO 14520 and TS EN 15004 standards
• Cylinders are CE marked and compliant with PED and TPED directives

The system is engineered to prevent total discharge in case of minor leaks, ensuring operational safety and testability after installation.

Technical Features

• Naturally occurring inert gas (Argon - Ar)
• Electrically non-conductive
• Leaves no residue after discharge
• No chemical decomposition products
• Safe for use in occupied spaces under design conditions
• Does not reduce visibility during discharge
• Odorless, colorless, and tasteless
• No ozone depletion or greenhouse effect contribution
• Corrosion-free storage and handling

Applications

IG-01 Argon systems are suitable for protecting critical infrastructure, including:

• Archives and document storage facilities
• Museums and cultural heritage sites
• Laboratories and research centers
• Metro stations and transport control rooms
• Electrical switchgear rooms
• Low and medium voltage electrical rooms
• Monitoring and control centers
• High-value equipment storage areas

System Configuration

IG-01 systems operate with high-pressure storage cylinders, typically:

• 80L and 140L cylinder capacities
• Storage pressures of 150, 200, or 300 bar

Higher pressure systems (300 bar) allow fewer cylinders, reducing installation space requirements.

A single system can protect multiple zones using directional valves, improving cost efficiency in large facilities.

Fire Suppression Performance

The extinguishing process is based on oxygen reduction to a safe inerting level:

• Design concentration for Class A fires: approx. 41.9%
• Extinguishing achieved through oxygen displacement
• Rapid discharge ensures fire suppression before flashover

Safety and Environmental Benefits

IG-01 Argon systems provide significant safety and environmental advantages:

• Safe for human-occupied environments
• No toxic residue after discharge
• No chemical reaction or harmful by-products
• Zero ozone depletion potential (ODP = 0)
• No contribution to global warming
• Maintains visibility during discharge, enabling safe evacuation

Maintenance and Monitoring

To ensure system reliability:

• Cylinders are continuously monitored via pressure switches
• Periodic inspections are required for all components
• Hydraulic performance is verified through certified calculation tools
• Relief dampers are sized according to structural leakage analysis
• Regular system testing ensures readiness at all times

Conclusion

The IG-01 Argon gas fire suppression system is a highly reliable inert gas solution for protecting critical and high-value assets. With its clean discharge, environmental neutrality, and compliance with international fire safety standards, it offers a robust and sustainable fire protection strategy for modern facilities.
