Wet Chemicals Systems provide a fast knockdown of high temperature cooking-oil fires. On contact with cooking oil the wet chemical seals the fuel surface and provides rapid cooling to prevent re-ignition.

Firepro Systems Ltd supply kitchen hood protection systems that use a wet chemical extinguishant. These are used in restaurants, fast food outlets and other cooking oil processes. The system consists of a cylinder containing the wet chemical agent, pipe work, nozzles and a heat detection system. The nozzles are arranged to protect the main risk areas, including the surface area of the process beneath the hood and the extraction ductwork.
