BETE HydroWhirl Orbitor (HWO) Tank Cleaning Machines

Rotary Jet High-Impact Tank Cleaning Devices for Large Tanks

The BETE HydroWhirl Orbitor Spray Nozzle is a versatile tank cleaning machine designed to meet the high standards required in the food, brewing, beverage, dairy, tanker cleaning, and chemical industries combining high performance cleaning efficiency with extended operating life and reduced life cycle costs.

BETE HydroWhirl Orbitor Design Features 

  • Can be stripped, maintained, and rebuilt in less than 15 minutes.
  • Self cleaning and self lubricated.
  • Enhanced external cleaning with dedicated nozzles that clean the external surfaces of the machine and its mounting pipe.
  • Designed for use where high impact cleaning is required.
  • Ideal for use in larger tanks and where the product is difficult to clean.
  • Designed with minimum moving parts to ensure extended operating life and reduced down time.
  • Ideal for use in larger tanks and where the product is difficult to clean

Key Features and Benefits of the BETE HydroWhirl Orbitor

  • Designed to meet hygienic standards
  • Optimum consumption of water, chemicals, and time = reduced operating costs
  • Minimum moving parts = reduced lifecycle costs
  • Self cleaning; self lubricating = no process contamination
  • High impact jets; orbital wash pattern = high efficiency cleaning process
  • Compact design = will fit through small access flanges
  • 2 or 4 nozzle configuration = wash pattern variable up to super intense
  • External Surface Finish: 0.5 microns Ra or better

Available Versions

  • 2 or 4 nozzle machines
  • Variable cycle time
  • Male or female connections

Spray Characteristics of the BETE HydroWhirl Orbitor

  • Variable cycle times
  • High impact cleaning
  • Working Pressure: 45 – 145 psi (3 – 10 bar)
  • Minimum opening size for standard-capacity HydroWhirl Orbitor is 125 mm (5.00″) for either a 2 nozzle or 4 nozzle model.

How Spray Pattern is Achieved

  • Rotary jets use the spray media flowing through internal gears on the body to rotate sets of high-impact jet nozzles through an efficient 2-axis orbital pattern, providing complete 360° coverage.
  • The jet pattern nozzles utilized on these assemblies provide significantly more impact and impingement force than other styles of tank cleaning nozzles, making them ideal for hard-to-clean residues and larger vessels.
Available Spray Angle Flow Rate Range
360° 21.5 to 163 gpm
Available Connection Types Material
  • Pipe: 1, 1 1/2
  • Connection Methods: Thread (NPT, BSP, Female)
