General Information

Description

  • Hollow cone spray pattern with a circular impact area
  • Large, unobstructed flow passages minimize clogging
  • Good atomization of liquids at lower pressures – ideal for fluid cooling applications
  • Removable caps for easy inspection and cleaning on some models
  • Slope-bottom design models reduce the drilling effect of the fluid vortex in the fluid chamber and premature wear
  • AX and BX nozzles form smaller drops; ideal for use in air washers and dust suppression applications
  • CX, CF, CRC and D nozzles feature higher flow rates; ideal for use in larger, evaporative cooling spray ponds
  • AP, LAP and LBP nozzles are constructed of polypropylene and feature excellent corrosion resistance at temperatures up to 160°F (71°C); patented center post design provides extended wear life of the nozzle
  • Standard, wide and extra wide spray angles

Flow

As liquid enters the nozzle, it passes into a whirlchamber and begins to spin in a circle at high speed. The rotation forces the liquid away from the center toward the edges of the whirlchamber. This causes the liquid to exit the orifice in a hollow cone pattern. Some WhirlJet nozzles have a slope bottom in the whirlchamber that helps extend wear life.
