Carbon dioxide as an extinguishing agent is swift and through. Within seconds, it smothers a fire and hold damage to a minimum. Stored under pressure as a liquid, carbon dioxide quickly expands to vapour and a state of fine particles of dry ice, much like snow. This “snow” absorbs heat rapidly changes to a vapour under normal temperature condition, and even faster in the presence of fire.

The carbon dioxide vapour chokes of combustion, and the snow effect reduces the ambient temperature to help prevent re-ignition. Moreover, carbon dioxide is a three dimensional agent, enabling it to penetrate the entire hazard area, including electrical cabinets. Low-pressure and high-pressure carbon dioxide systems have equal extinguishing capabilities when each is designed to handle a specific hazard.
