A Low Velocity Water Spray System (LVWS) is a type of fire protection system commonly used in industrial settings to suppress fires involving flammable liquids, gases, or other hazardous materials. Unlike high-velocity water spray systems, LVWS systems operate at lower pressures and velocities, providing a gentler application of water for fire control. Here's how it typically functions:
LVWS systems require a reliable water supply, which can be provided from a dedicated water tank, a municipal water line, or both. Pumps and water storage tanks may be included in the system to ensure an adequate water supply is available when needed.
The system consists of strategically placed nozzles and distribution piping that cover the area to be protected. These nozzles are designed to produce a low-velocity water spray pattern, which can effectively suppress fires without causing excessive water damage to surrounding equipment or materials.
LVWS systems can be activated manually by personnel or automatically through the use of heat or smoke detectors, flame detectors, or other fire detection devices. Once activated, the system releases water at lower pressure and velocity compared to high-velocity systems, creating a gentle curtain of water spray.
The low-velocity water spray helps to cool the fuel surface, reduce the temperature of the fire, and prevent the spread of flames. While not as forceful as high-velocity systems, LVWS systems can still effectively control and suppress fires involving flammable liquids or gases.
LVWS systems may be equipped with control panels and monitoring devices to ensure proper operation and provide feedback on system status. This allows for quick detection of any issues or malfunctions that may arise, ensuring the system remains ready to respond to fires effectively.
