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.
