BETE HydroWhirl® S (HWS) Tank Cleaning Nozzles

Efficient Reactionary Force Tank Cleaning Devices

The BETE HydroWhirl S tank cleaning nozzle directs the cleaning water through a rotating head at the tip of the spray assembly. This process produces a vigorous moving spray action against all areas of the walls of a tank. The spray pattern from the HydroWhirl S cleaning nozzle uses impact and repetition to wash the tank quickly. The spray pattern is especially effective at breaking up and removing contaminants. An outstanding design, quality, and engineering combination, the HydroWhirl S nozzle is ideal for anyone who needs reliable, efficient cleaning of tanks and other interior spaces.

Design Features of the BETE HydroWhirl S Spray Nozzles

  • Cleans more quickly but uses less water and lower pressure than static spray balls
  • Reduced flow and pressure with the smaller pump size resulting in less operating costs
  • Exterior coating is ideal for sanitary applications
  • Laser welded design – durable assembly
  • 316 Stainless Steel construction – corrosion resistant
  • Three connections – threaded, clip-on, and welded
  • Made from FDA-accepted materials for Clean-in-place (CIP) applications

How Spray Pattern is Achieved

  • The HydroWhirl S tank cleaning nozzle sends solution through a rotating head at the tip of the spray assembly and produces an intense moving spray action, cleaning all areas of the tank walls.
  • Through force and repetition, the spray pattern from the HydroWhirl S cleaning nozzle quickly cleans tanks.
