NCJ Hollow Cone and Narrow Angle Injector Nozzles

Whirl Spray Nozzles

Whirl nozzles generate a whirling motion of the liquid. Axial whirl nozzles produce the swirling motion with an internal vane or disc. Tangential whirl nozzles feature a slight angle on inlet passageway into the cavity of the nozzle. The swirling effect within the body cavity creates the whirling motion.

• The Axial Whirl full cone nozzle style is ideal for an even distribution over a packed bed.
• The Axial Whirl full cone nozzles is used for rain simulation and foam control applications.
• Spillback nozzles provides a 10:1 turndown ratio with minimal change in drop size.

    • Internal Whirl vane/disc to help create the spray pattern.
    • Inlet inline with outlet.
• Tangential
  • Full Cone
    • Even distribution of the droplets.
    • Slight angle on inlet passageway into the cavity of the nozzle to create the swirling effect within the body cavity, thus resulting in the creation of the spray pattern.
    • Liquid inlet 90 degrees from liquid outlet.
    • Fins on one side of the body cavity to disrupt the swirling action to help direct droplets to the center of the spray pattern.
  • Hollow Cone
    • Slight angle on inlet passageway into the cavity of the nozzle to create the swirling effect within the body cavity thus resulting in the creation of the spray pattern.
    • Liquid inlet 90 degrees from liquid outlet.
