BCD Fire supplies fire hose reel systems which contain a high-pressure hose that carries water or other fire -retardant materials to the fire to extinguish it. Outdoors, they can be attached to either to a fire engine or a fire hydrant. Indoors, they can permanently attach to a building’s standpipe or plumbing system. The usual working pressure of a fire hose can vary between 8 and 20 bar.
