The original "clean" agent, carbon dioxide suppresses fire without leaving behind an agent to damage sensitive equipment. And because there is no agent to clean up, you’re back in business faster. To provide the most economical system arrangement without sacrificing performance, we offer both High and Low pressure systems.
Carbon dioxide is a plentiful, non-corrosive gas that does not support combustion nor react with most substances. It is commonly compressed to the liquid state for storage and transportation in TPED cylinders.
Upon release, it discharges under its own pressure giving the appearance of steam as its low temperature crystalizes water in the air. For fire suppression purposes the discharge is designed to raise the carbon dioxide concentration in the hazard.
This removes the free oxygen which supports combustion*, and results in fire extinguishment. The resultant lack of free oxygen dictates that total flooding hazards be evacuated immediately, and carbon dioxide from local application be avoided by personnel.
