These systems are crucial for modern fire safety and this article describes their functioning and importance in a data center or a laboratory or other critical spaces so you could protect them better.

What is a Gas Fire Extinguishing System?

A gas fire extinguishing system uses inert or chemical gases to extinguish fires. These systems either reduce the oxygen levels like suppression in the designated area or interrupt a fire’s chemical reaction. Gas fire extinguishing systems are effective for sensitive environments such as server rooms, laboratories, and archives since they cause no residue damage and minimal destruction to equipment or property.

How does a gas extinguishing system work?

A sophisticated method involving a series of processes through gas fire extinguishing systems work, including the detection of fire, suppression system activation, and gas discharge. Advanced sensors monitor for fire or smoke and trigger alarms which activate a systems countdown for evacuations. Upon activation, suppression gas is released into the designated area which dramatically reduces oxygen levels or disrupts the fire combustion’s supporting chemical reaction.

Key Components of a Gas Suppression System

• Detection System – Includes devices such as sensors and detectors that analyze all areas for fire or smoke, early on in the process.
• Control Panel – Oversees system functions, activates necessary alarms, and gas discharge.
• Suppression Agent Storage – Tanks, or cylinders that store the fire suppression gas.
• Discharge Nozzles – Set free the suppression gases into the safeguarded zone.
• Alarm System – Notifies users of a fire hazard and gives time to escape.
• Piping Network – Transfers the suppression agent from storage containers to the nozzles.

Why choose a gaseous fire suppression system over others?

Gaseous fire suppression systems have obvious advantages over traditional fire suppression systems using water sprinklers and foam. They utilize clean agents like FM-200, NOVEC 1230, or even some inert gases tailored to suppress fires without endangering critical electronics, infrastructures, or sensitive materials. These systems are known to extinguish class A (combustible materials), class B (flammable liquids), and at times class C (electrical) fires, so they can be used in different areas.

One major benefit is speed with which they operate. Research shows that MV-210 fire systems suppress fires within seconds of detection. For example, NOVEC 1230 is known to have a discharge time of under 10 seconds, responding quickly to potential fire hazards. Moreover, fumes from agents put under pressure do not require decontamination works after usage, which greatly differs from water systems.

Moreover, these systems have a compact spatial footprint. For instance, inert gas systems are stored in space-saving, compact high-pressure cylinders ideal for data centers, archives, and laboratories. Their environmental performance is also noteworthy. NOVEC 1230 has a global warming potential (GWP) of 1 and an atmospheric lifetime of 5 days, meeting sustainability objectives and global environmental requirements.

In the end, the focus for customers wanting to protect valuable assets with eco-sensitive fire suppression systems would be gaseous systems. These are best suited for high-value applications, including datacenters, telecommunication centers, museums, and healthcare facilities.
