This self-contained automatic fire extinguishing system provides simple and effective protection against fire for deep fat. It is capable of quick detection and extiguishing split blazing oil fires.
The system can be designed to provide protection for one deep fat fryer (50 litres, 800mm xm400mm) and up to three deep fat fryers (each 27 litres, 400mm x 360mm).
The system uses water with additive (foam) to extinguish fire. The AFFF foam increased the wetting power and penetration capacity of water by reducing its water surface tension. It forms a highly mobile watertight film, which reforms immediately when the surface is disturbed. The film is impermeable to flammable liquid vapour discharge and prevents re-ignition. Co2 gas stored in a cartridge is used to propel the extinguishing agent. The discharge nozzles spray the extinguishing agent onto the fire, which are installed above the fryers but below the galley hood.
Detection for automatic operation is by thermal fuses. These fuses trigger at temperature equal to 110 deg C or higher.
System Layout
The system consists of one 9 litres extinguisher with AFFF additive (CD certified). It must be installed near the protected risk. A diffusion strip is fitted with one full jet nozzle for each risk area to be protected (stainless steel nozzle bracket and nozzles). The maximum length of pipe work between the extinguisher and the last nozzle must not be more than 9mtr. A fuse chain equipped with thermal fuses (1 per risk) installed int he top centre of teh cooker hood triggers the system automatically. The fuse chain is at the same height as the diffusion strip (1.15mtr to 1.3 mtr) and is installed above each risk area. A manual control is installed near to the extinguisher or at a visible places for the galley crew.
