High Velocity Water Spray Nozzles are internal swirl
plate type open nozzles designed for use in fixed
water spray or deluge system for the fire protection
application.
These nozzles produce solid uniform and dense core
of high velocity water spray for effective fire control.
Nozzles are normally used to cool the surface as
well as for extinguishment. High Velocity Water Spray
Nozzles are typically used for Deluge protection
of special hazards such as oil filled transformers,
switch-gear, chemical process equipments, conveyor
system and flammable liquid storage areas. The
minimum desirable pressure to achieve a reasonable
spray pattern is 3.5 kg/sq.cm (50 psi). The water
distribution pattern is as shown in the graph in
following pages giving maximum effective axial
distance from the nozzle. The spray pattern shown is
considering indoor areas. The system designer must
consider wind velocity while designing the system for
outdoor application. Field obstruction if any, affecting
the spray pattern of the nozzle must be considered.
The nozzle may be oriented in any position as deemed
necessary to cover the hazard.
