Tank spray devices selected from geometry, soil and available CIP supply
Select the spray device with the vessel drawing and the intended cleaning duty in view. A catalogue cleaning diameter leaves questions about internal obstructions, available flow and pressure, soil and installation. Agree the exact device configuration and the evidence needed at handover.
Selection of static and rotary spray balls by device rating, pattern, tank geometry, hygienic interfaces and coverage testing. Cleaning mechanisms and soil-removal studies are discussed on Spray Balls/Nozzles; complete CIP skids, circulation pumps and chemical-dosing equipment are separate supply scopes.

Read the pressure and flow as a device operating point
GEA’s static spray-ball range uses high-flow flushing at low pressure and has no wearing parts. Its public range data recommend 1–2.5 bar and list cleaning diameter up to 8 m. These are range-level references, requiring the selected size and pattern. [1]
Request the offered device’s flow-versus-pressure data and the proposed operating point. Check pressure at the installed inlet after elevation and pipe losses, together with the return capacity of the cleaning circuit.
China Sanitary Valve’s rotary-ball page lists welded, clamped, threaded and bolted connections, alongside fixed-ball variants. Identify the supplied construction before comparing its connection or operating requirements. [3]
Supply the vessel drawing, soil and cleaning recipe, inlet flow/pressure, drain arrangement, connection and proposed acceptance conditions together.
02
Use riboflavin to assess spray coverage
STERIS describes coating the vessel with riboflavin, rinsing through the spray device and inspecting under UV light. Remaining fluorescence identifies inadequate spray coverage; repositioning or adding devices may be followed by another coverage test. [2]
Specify the installed configuration, test conditions, accessible inspection areas and acceptance record with the supplier. Include fittings and other features that could obstruct the spray.
A coverage result addresses where the test spray reached. Establish residue-removal and other cleaning-process acceptance separately; a coverage test alone leaves those questions unanswered.
03
Keep catalogue diameter limits with their named devices
Spraying Systems Co. lists TankJet 63225 and 63225-3A spray balls for tanks up to 13 ft. The same catalogue includes a stationary 12900 nozzle for tanks up to 20 ft and fluid-driven and motor-driven cleaners with other limits. These are different devices, rather than a universal diameter rule for changing cleaning technology. [4]
Ask for the exact model’s effective reach, pattern and placement proposal in the supplied vessel. Check the inlet opening and obstructions as well as diameter and height.
Keep wetting or nominal spray reach distinct from cleaning performance on the intended soil. Agree the cleaning cycle and installed demonstration for that device and vessel.
Compare the quoted model and operating conditions, rather than assigning every product on a category page the category’s largest tank diameter.
04
Define the fixed or rotating construction in the quotation
Connection variants and a rotating head change the assembly and maintenance requirements. Identify the supplied ball, nozzle or cleaner as a complete configuration. [3]
Request an assembly drawing and the retained mounting dimensions. For a rotating design, identify the drive, bearings and service parts and agree how rotation will be checked in operation.
Specify wetted materials and finishes for the cleaning chemistry and temperature. Obtain documentation for any claimed hygienic approval against the exact product and configuration.
05

Buyer questions
Does the largest diameter on a catalogue page apply to every spray ball?
Each named device has its own limit. The catalogue includes both stationary and moving cleaning devices. [4]
What does a riboflavin test establish?
It assesses spray coverage using fluorescence after a defined rinse. Agree cleaning-process acceptance separately. [2]
Can the CIP pump discharge pressure be used as the ball inlet pressure?
Account for the installed circuit and agree the operating point at the device inlet. GEA’s listed pressure is range guidance for its static balls. [1]
Are all spray-ball connections interchangeable?
Connection types vary. Match dimensions and retention details from the device and vessel drawings. [3]
Sources and what still needs a direct check
Sources checked 2026-10-19. GEA supplies static-ball range data; STERIS explains a coverage test. The Spraying Systems catalogue lists different cleaning-device models and limits, while China Sanitary Valve shows connection and construction variants. Verify current documents for the exact order.
