ELITE K-12 are systems designed for extinguishing fires in commercial kitchen hoods. They can be installed easily in any model of extractor hood. Both kits work as fully autonomous systems, with full and instantaneous detection at any point of the hood, also contemplating the possibility of manual activation. The systems release through diffusers, an ecological foaming agent, non-toxic and non-corrosive, covering the entire hood completely, both the work areas, as filters, plenum and extraction ducts, producing an effective extinguishing with a double cooling effect and containment of fire.
