ISE – HV SN High Velocity Water Spray Nozzle

High-velocity spray nozzles are essential for both surface cooling and fire extinguishing in high-hazard areas, such as oil-filled transformers, chemical process equipment, conveyor systems, and flammable liquid storage. For optimal performance, a nozzle pressure of 3.5 bar to 7 bar is recommended, allowing for the rapid extinguishing of fires through the process of emulsification. While these nozzles feature built-in strainers to prevent internal clogging, it is still required to install a main strainer in the system pipeline to ensure continuous, reliable operation.
