CO2 gas fire suppression systems are used in areas where there are no people present, where airtightness is ensured, or where an acceptable level of openness is maintained. Unlike clean agents, CO2 gas fire suppression systems can be applied in localized applications.
The advantages of CO2 gas fire suppression systems include their cost-effectiveness, the absence of airtightness requirements, and the ability for localized application.
However, alongside these advantages, there are some disadvantages to CO2 gas fire suppression systems. They should not be used in areas where there is a possibility of human presence. Additionally, due to the high amount of heat absorption, CO2 can create water crystals in electronic areas, which can be a drawback.
