Ultrasonics boost productivity of turbochargers

Kerry Ultrasonics product story

Productivity at Garrett Engine Boosting Systems has increased by 20 per cent following the installation of a special two-stage ultrasonic clean and dry system.
Productivity at Garrett Engine Boosting Systems has increased by 20% following the installation of a special two-stage ultrasonic clean and dry system from Kerry Ultrasonics.
The new machine removes light oils and grinding swarf from steel turbocharger shafts destined for passenger cars and commercial vehicles.
Shafts now demonstrate contamination levels 50% less than those achieved by the previous dishwasher-type non-Kerry unit.
Kerry's Microclean system is manually operated but PLC-controlled.
It uses a mild biodegradable alkaline detergent with a rust inhibitor in the cleaning stage.
Since they are not rinsed, shafts leave the hot air drying stage coated with the inhibitor and are therefore less prone to corrosion.
A full particulate filtration system prolongs the life of the cleaning tank.
Finished components must satisfy Garrett's strict contamination tests, which improve on automotive industry standards.
Garrett had considered spray wash cleaning methods but found that only the use of ultrasonics could guarantee consistently acceptable test results.
"Kerry is a world leader in ultrasonic technology," commented Harry Smith, Operations Engineer at Garrett, when asked to explain why Garrett chose Kerry over two other UK-based cleaning systems suppliers.
"They design and manufacture in-house and offer excellent customer support.
The reliability and compact size of the Microclean machine were also key factors.".
