The most common types of clean agent systems use chemical agents like FM-200 (HFC-227ea) and 3M Novec 1230 or inert gases, which are made up of gases like nitrogen, argon, and carbon dioxide. All clean agents are stored as either a gas or liquid and when the system activates, it releases the clean agent as a gas to suppress the fire. Upon discharge, the clean agent removes or disrupts one of three elements needed to sustain a fire – heat, oxygen, or the fuel source. Most clean agent fire suppression systems reach extinguishing concentration levels in just 10 seconds or less, making them highly efficient in suppressing fire before significant damage can be done. Because clean agents quickly evaporate, there is minimal downtime as no clean-up is required.
