IG541 gas (52%N2, 40%Ar, 8%CO2) is a mixture of mainly nitrogen, argon, and carbon dioxide. It has good fire-fighting performance and electrical insulation performance, and is widely used in the following fields:

1. Fire extinguishing system: IG541 gas is widely used in automatic fire extinguishing system, especially for electronic equipment, computer rooms, communication equipment rooms, data centers and other important places to extinguish fire and protect equipment from fire damage.

2. Power industry: IG541 gas can be used to protect generators, substations, power equipment and other important electrical facilities to prevent fire from causing serious losses to the power system.

3. Electronics industry: Because IG541 gas is non-corrosive to electronic equipment, it is widely used in semiconductor production process, electronic manufacturing process and other fields to protect equipment and products.

4. Storage and logistics: IG541 gas can be used to protect valuable items in warehouses, storage areas and logistics transportation, such as documents and archives, museum relics, works of art, etc., to prevent losses caused by fire.

5. Chemical industry: IG541 gas can be used for fire suppression and protection of reactors, storage tanks and other equipment in the chemical industry.

In summary, IG541 gas is widely used in places and industries where it is necessary to protect valuable equipment, prevent the spread of fires, and reduce damage after extinguishing.
