Overview

These nozzles are designed to be installed in groups or zones of protection and operate simultaneously to control and suppress fires involving inflammable and flammable liquids and gases. The type of nozzle, the flow rate, and discharge angle is determined by the type of risk involved.

These groups of nozzles are linked to a detection airline and a Deluge system control valve.  In the event of a fire, the devices in the detection airline operate to release air within the system.  This in turn operates the Deluge system control valve, which opens to discharge water simultaneously through all the open nozzles within the protected area.

Medium Velocity water spray nozzles can also be used with low expansion foam for small bund protection to suppress hazardous chemical vapours that may occur as a result of storage tank rupture.
