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 2 to 3 bands of relatively coarse droplets, surrounded by wider bands of relatively fine droplets.
The large surface area of spray improves evaporation and cooling.
