Combination distribution Nitrogen injection oxygen control fire prevention system for warehouses
Nitrogen injection oxygen control fire prevention system with air as raw material, nitrogen and oxygen in the air are separated by the gas separation unit, and nitrogen is injected into the protection area to inhibit oxygen concentration, so that the combustible in the protection area will not burn. It is suitable for Electrical equipment places with solid, liquid and gas combustibles; Unattended and unattended places (such as oil storage tanks, dangerous goods warehouses, etc.); Places where people stay for a short time (such as computer rooms, power distribution rooms, cable interlayers, cable slots, cable tunnels, warehouses, archives, tobacco warehouses, collections, cultural relics, communication and telecommunication equipment rooms, etc.); A place without adverse effects in a low oxygen environment;
