Deluge systems are designed to protect high-hazard areas such as tunnels, oil refineries, chemical facilities, offshore platforms, and power plants. These locations frequently contain highly flammable, combustible, or explosive materials that require robust fire protection systems.
Deluge systems utilize open nozzles or open sprinklers, with system piping open to atmosphere and water under pressure held below the clapper of the valve. Deluge systems require a detection and release system. When activated by a detector, the valve opens, allowing water to flow into the system pipe and through all nozzles or open sprinklers.
