Dry Pipe Sprinkler System – Working Principle A Dry Pipe Sprinkler System is an automatic fire protection system designed primarily for areas where low or freezing temperatures could cause water-filled sprinkler pipes to freeze and become damaged. It is commonly used in locations such as cold storage areas, unheated spaces, parking areas, warehouses, and other temperature-sensitive environments. How the System Works Under normal conditions, the sprinkler piping is not filled with water . Instead, the pipes are maintained with pressurized air or nitrogen . Water is held on the supply side of a dry pipe valve , which prevents water from entering the sprinkler piping until the system is activated. When a fire occurs, the heat generated by the fire causes the nearest sprinkler head to reach its operating temperature. The sprinkler head then opens, releasing the pressurized air or nitrogen from the piping. As the compressed air pressure decreases, the pressure difference across t...
