The function of the Discharge Nozzle is to distribute the Clean Agent in a uniform, pre-determined pattern and concentration. The nozzles are designed to complete the discharge in 10 seconds, or less, when installed within the design limitations of the Shield Design, Installation, Operation, & Maintenance Manual (SD000003).
Discharge Nozzles are available in sizes ranging from ½” to 2½”. Each nozzle is available in two configurations: 180 and 360 degree distribution patterns, and is made of aluminum, brass, or stainless steel with female pipe threads. Orifice sizes are determined by hydraulic flow calculations. All nozzles are rated for a maximum hazard height of 14 feet. If hazards exceed 14 feet in height, a second tier of nozzles must be used.
