FM-200 is the most widely used Halon replacement. It provides a rapid suppression with a short discharge time of typically six to ten seconds. With a relatively small cylinder storage footprint, it is ideally suited to use in areas where space is at a premium or weight restrictions apply. Effective on class A, B or C fires FM-200 extinguishes fires quickly through a combination of chemical interaction and physical heat removal. The device does not smother flames but removes heat from fire and not oxygen from the environment. FM-200 absorbs heat from the flame zone and interrupts the propagation of the combustion process.
Argonite is an inert gas blend of argon and nitrogen, which occur naturally in the environment. It works by displacing oxygen and reducing it from the normal 21% to a level that will not support combustion. The space required for inert gas storage cylinders is greater then that needed for chemical agents. The cylinders are mounted in rows and may be stored in any suitable location, even up to 100 metres away from the protected areas.
Clean agent carbon dioxide systems, have been an industry standard for many decades and are still the preferred agent in many applications. CO2 is a colourless, odourless, dry, inert gas and is one of the most well known of all fire extinguishants. Highly versatile, it can be used for total flooding or in local application. Another advantage is that it is relatively inexpensive due to being readily available for low cost total re-charge.
