IG541 gas fire extinguishing equipment

PRODUCT DETAILS

Overview

The IG541 Fire Extinguishing System uses IG541 as the extinguishing agent, a mixture of three gases: Nitrogen (N2), Argon (Ar), and Carbon Dioxide (CO2), mixed in the following proportions: 52% ± 4%, 40% ± 4%, and 8% +1%/-0.0%, respectively. It extinguishes fires through a physical mechanism by reducing the oxygen content in the air within the fire's combustion zone. The characteristics of IG541 include being colorless, odorless, non-toxic, non-corrosive, and non-polluting. It has an Ozone Depletion Potential (ODP) of 0 and a Global Warming Potential (GWP) of 0, making it an environmentally friendly fire extinguishing agent and an ideal alternative to Halon.

The system consists of an extinguishing agent storage cylinder group, container valves, check valves, selection valves, driving devices, distribution pipes, pressure-reducing devices, signal feedback devices, nozzles, and a control system.

Fire Extinguishing Principle

When the fire suppression system is in automatic control mode, and a fire occurs in the protected area, the fire detectors emit a fire signal. The alarm controller immediately activates both audible and visual alarms. The gas fire control panel receives two independent fire alarm signals and issues a linkage command to shut off related equipment. After a 30-second delay, the extinguishing command is issued, which opens the corresponding solenoid valve and activates the driving gas. The driving gas flows through the activation pipeline, opening the relevant selection and container valves, releasing the extinguishing agent, and extinguishing the fire.

Application Scope

IG541 is suitable for extinguishing the following types of fires:

Electrical fires
Liquid fires or fires involving molten solids
Solid surface fires
Gas fires where the gas supply can be shut off before extinguishing

It is suitable for protecting enclosed spaces, including typical areas such as:

Electrical and electronic equipment rooms
Communication equipment rooms
National heritage protection sites including metal, paper, and silk-based cultural artifacts, as well as audiovisual and archival storage
Flammable and combustible liquid storage rooms
Locations with combustible gas fire hazards, where the combustible and supporting gases can be cut off before discharging the extinguishing agent
Protection areas with regular human presence, etc.
