SPIRAL FULL AND HOLLOW CONE SPRAY NOZZLE
Detail Full Cone Spray Pattern IconDetail of the Hollow Cone Spray Pattern Icon

DESIGN FEATURES

The original spiral nozzle invented by BETE

Also referred to as pigtail nozzles, corkscrew nozzles, or helix nozzles

High energy efficiency

One-piece/no internal parts

Clog-resistant performance

High discharge velocity

Commonly used for quenching, scrubbing, and evaporative cooling


HOW SPRAY PATTERN IS ACHIEVED

The spray pattern of the spiral nozzle is formed by the fluid shearing along with the turns of the spiral, which produce multiple concentric cones. These cones form two to three bands of relatively coarse droplets surrounded by wider bands of relatively fine droplets

Produces the finest droplet size of any direct pressure nozzle for very fine atomization
