How it works


Effective: 100% Cleaning, Everytime.

Our patented rotary impingement tank cleaning combines impact and precision. The impact, also known as impingement, creates two jet streams which scour the tank interior and blast away residue and contaminants. Whereas the precision ensures every square inch of the tank has been contacted by a jet stream. This combination ensures the tank or vessel is thoroughly cleaned, every time.


Understanding Impingement

Imagine your garden hose and a mud ridden fence. Without a nozzle, water falls from the hose. This water over time may “erode” away the mud on the fence, however if you were to slide your thumb over part of the opening, pressure builds behind the water and blasts away the mud. As it hits the fence, it radiates outward, maintaining low pressure and flow, but optimizing the impact or mechanical force. This is impingement. Impingement, is what sets us apart from other automated tank cleaners. Force. Our machines are capable of creating up to 85lbs (39 kg) of force at a 25’ (7.5 m) distance with minimal pressure and flow. This is impossible with any other technology.




Understanding Precision

Our rotary impingement process is mechanically engineered (gear-driven) to scour every square inch of the tank or vessel in a repeatable and reliable manner. As the nozzles rotate on a vertical plane, they index two-degrees on a horizontal plane, creating a repeatable and reliable, full-coverage, pattern. The speed of rotation is mechanically designed into the machine based on pressure and flow. Therefore if these factors (pressure and flow) remain constant, the cleaning pattern remains constant and the machine cleans in the exact same pattern at the exact same speed, every time. Wear parts have no effect on this process, making it 100% validatable. We also have a validation accessory for extra assurance. Click to learn about the Alfa Laval Rotacheck
