Rotary spray balls

Rotary Spray Ball

Also known as spinners, reactionary force cleaning heads or rotary nozzles, these come in a variety of models. They are fluid-driven, using the tank's spray media's reaction force to drive the nozzle head's rotation. They provide complete 360° coverage and efficient cleaning through impact and repetition. Rotating nozzles increase tank washing efficiency over static spray balls, saving time and money by reducing water and cleaning agent consumption while decreasing downtime.

Rotary spray balls produce three fan sprays.  These fan sprays rotate and so sweep around the tank walls ensuring a complete clean.  The rotary motion is powered by the fluid itself and so no external power source is required.

These versatile cleaners are far more water-efficient than static nozzles/spray balls as the momentum of the spray is concentrated in three fan sprays rather than distributed into scores of micro jets (as with spray balls) or into a very wide angle spray pattern (as with spiral nozzle tank cleaners).

Limitations

Rotary spray balls are a cost effective way of cleaning medium sized tanks but they will struggle to effectively clean tanks with a diameter of much more than 5 metres.

Whilst the impact of the cleaning spray is greater than static nozzles and spray balls, it will still take time to break down tough residues.  This means that for very sticky or burnt-on contaminants rotary spray balls may not be the most water efficient cleaning system and instead rotary jet cleaners should be considered.

Uses

Rotary spray balls are amongst the most versatile of tank cleaning systems.

Their small size and slim profile means they can be inserted through an opening as small at 17mm meaning they can be used in almost any tank.

For smaller tanks they will almost always improve the water efficiency of the clean over static nozzles.

For larger tanks they represent a cheap, low pressure way of cleaning or rinsing medium to tough residues although they may need to be run for considerable lengths of time to clean some tanks.   

Models

RSB25 - The RSB is a spinning tank cleaner suitable for cleaning small and mid-sized vessels. It is self-cleaning and has a completely hygienic design meaning it is commonly used in food and pharmaceutical applications

HydroWhirl® Mini SS and HydroWhirl® Mini PVDF - The compact size of these HydroWhirl® Mini heads make them ideal for cleaning small spaces. The Mini SS is targeted at food processing equipment cleaning including pipe and bottle cleaning and cleaning dispensing equipment while the PVDF version is used for cleaning harsh chemical residues in pipes and processing equipment.

HydroWhirl® Disc -This fully submersible, clog-resistant rotary head has the largest capacity free-spinning design with powerful flat spray nozzle inserts. It is suitable for cleaning medium-sized tanks.

HydroWhirl® Stinger - This rotary cleaning head is suitable for small-medium sized vessels with light to moderately tough residues. It has a unique patent-pending pipe thread technology to reduce contamination and bacteria growth and zirconia ceramic bearings for long service life and extreme chemical resistance.

HydroWhirl® Poseidon - Made from corrosion resistant PTFE, the Poseidon is ideal for harsh chemical environments, chemical processing tanks and IBC tote cleaning.

EK Pop-up - The retracted EK nozzle presents a smooth surfach flush with the tank wall. When fluid is turned on, the nozzle's spinning head moves out from its body. It is ideal for spot cleaning difficult to reach parts of a tank.
