The Principle and Application of CO2 Gas Fire Extinguishers

What is a CO2 Gas Type Fire Extinguisher?

A CO2 gas type fire extinguisher is a type of clean gas extinguishing equipment widely used in environments that require high protection and contain precision equipment. After extinguishing a fire, it does not cause damage or corrosion to the environment, electronic equipment, or valuable items (such as books, archives, etc.), making it particularly suitable for libraries, museums, computer rooms, and precision instrument rooms that require high protection.

Principle of Extinguishing for CO2 Gas Type Fire Extinguishers

The working principle of CO2 gas type fire extinguishers is based on the suffocating effect of carbon dioxide. When the operator presses down the handle of the valve, the liquid carbon dioxide stored inside the cylinder flows out through a siphon tube and enters the nozzle. The ejected carbon dioxide quickly disperses into the combustion area, reducing the oxygen concentration to extinguish the flames. 

Additionally, the rapid vaporization of liquid carbon dioxide absorbs a large amount of heat, which not only helps to cool the burning material but also accelerates the extinguishing process. This cooling and suffocating effect of carbon dioxide makes it an effective extinguishing agent, especially suitable for flammable liquid, gas fires, and electrical equipment fires.

Applicability of CO2 Gas Type Fire Extinguishers

CO2 gas type fire extinguishers are particularly suitable for extinguishing initial fires of flammable liquids and gases. Since their extinguishing mechanism does not damage the environment or equipment, they are also commonly used for firefighting in electrical equipment fires. Typical application scenarios include:

• Laboratories: Protecting experiment facilities and chemicals.

  
  

• Computer Rooms: Protecting high-value computers and electronic equipment.

  
  

• Power Substations: Providing safety assurance for electrical equipment.

  
  

• Places for Valuable Items: Such as museums and libraries, to avoid damage to valuable books, artworks, and documents.

CO2 gas type fire extinguishers not only possess high extinguishing efficiency during initial fires but also effectively reduce the impact on equipment and the environment, making them an ideal choice for protecting precision instruments, electronic equipment, and other valuable items. By using a CO2 gas type fire extinguisher, you can confidently deal with fire accidents while ensuring the safety and integrity of your valuable items, avoiding the pollution or damage that traditional extinguishing agents may cause to equipment.
