HVWS – High Velocity Water Spray System
High Velocity Water Spray (HVWS) System is a type of fire suppression system that uses water to extinguish or control fires in high hazard areas such as oil refineries, chemical plants, and power plants. The system is designed to discharge a large volume of water at high velocity to create a curtain of water that can contain and extinguish fires.
The HVWS System typically consists of a network of pipes and nozzles that are strategically placed to provide maximum coverage. The system is activated by a fire detection system, which signals a control panel to open the water valve and release water through the nozzles.
The water is discharged at high velocity, creating a fine mist that cools the surrounding area and extinguishes the fire by removing heat and oxygen. The water can also act as a barrier, preventing the fire from spreading to other areas.
HVWS systems are commonly used in areas with high fire risks, such as flammable liquid storage areas, aircraft hangars, and turbine rooms. They are also used in industrial applications where machinery generates significant heat and fires can occur.
Proper installation, testing, and maintenance of HVWS systems are critical to ensure their reliability and effectiveness. Regular inspections, testing, and repairs can help identify and address any issues that may impact the system's performance in the event of a fire. The system must also comply with local building codes and regulations, which often include requirements for backflow prevention and regular testing.
