There any many different types of fire suppression agents on the market. All have their advantages and disadvantages.
In contrast, Chemical systems, such as FM-200 are very different.
These are manufactered chemical extinguishing agents, normally HFC's, which work at low concentrations and attack the fire directly at a molecular level, rather than by reducing Oxygen levels.
They are low pressure systems, generally 25 bar, and the agent is stored as a liquid, super-pressurised with Nitrogen to "push" them along the pipework.
Chemical Systems (FM200/NOVEC/CO2) v Inert Systems (i3/Inergen)
All of the fire suppression systems both Inert and Chemical are approved for use all over the world by bodies such as UL, FM, LPCB etc and are recognised by Environmental Agencies like the EPA as being suitable for use in normally occupied spaces.
These systems, which are stored at a pressure of between 150bar and 300 bar, extinguish fires in a passive manner. They reduce the Oxygen content within the protected enclosure to a point where fire can no longer survive.
The benefits of these type of system are :
