Frequently asked Questions for Thick Walled Fixed Spray Balls

Frequently Asked Questions

What is the optimum inlet pressure for a fixed spray ball

2 bar pressure

What is the maximum pressure for a Thick Walled Fixed Spray Ball

5 bar because the extra 3-4mm wall thickness acts as a nozzle

What are the benefits of a thick walled fixed spray ball over a standard 16 swg thin walled ball

Much better jet definition

Thick walled balls can be target drilled to guarantee passing Riboflavin coverage test of the tank

As the balls are manufactured individually they can be designed with any spray pattern design and flow and pressure requirement

They can also be fitted with Misting Nozzles to wash Bursting Disks in Pharmaceutical Vent Lines etc without damage to the fragile Disks

When would a thick walled fixed spray ball be used inplace of any other cleaning head technology

In a powder environment or where the end Pharmaceutical customer as a standard uses only fixed spray head technology

What Information Is Required To Size And Recommend A Specific Cleaning Head

Thick Walled Fixed Spray Balls

Is a Fixed Spray Ball Preferred

Is the application a simple to clean process vessel

Are targeted spray patterns required

Is a Riboflavin rinse test to be carried out during commissioning

What material certification is required with the balls

Will Welding certification be required

What internal and external surface finish is required

Will the balls require pickling and passivation and or electro polishing

Material of construction, PTFE, Hastelloy, 316L stainless steel etc

Required Tank/Application Information

What is the diameter, the height of the straight side, top dish and bottom cone of the tank

Where is the existing or potential positions for the cleaning head to be installed.

How many and in what positions are the inlet connections in the top dish of the tank

What are the inlet connection sizes in the top dish of the tank

Are there any internal Baffles, Agitators, Fill Pipes, Ladders or any other obstructions in the tank to potentially cause shadowing

What is the product to be removed from the internal surfaces of the tank, is it water soluble or will a solvent required

What flow and pressure is available locally to operate the cleaning head technology

What type of CIP recipe is proposed, just a cold or hot rinse or a full CIP cycle involving a pre rinse, caustic recirculation and final rinse etc

If it is an existing application requiring improved CIP performance, what is the existing pre rinse, caustic recirculation and final rinse cycle times
