ITW Pillar Technologies, manufacturer of advanced surface treatment and induction cap sealing systems, has been granted a patent for the industry’s first on-board Maintenance Indicator for corona treatment systems.
The Maintenance Indicator technology senses a specific level of contamination at the corona treater’s ground roll. When a certain level of contamination accumulates at the ground roll surface, treatment level sub-optimization effects will occur in the form of backside treatment. 
“This deterioration in surface treatment level can go undetected by packaging converters for extended periods of time and result in significant amounts of non-performing and rejected product.” said Steve Helker, ITW treatment systems sales manager. “It will also be very likely that at the time the Maintenance Indicator activates a signal to operators, other key internal components such as electrodes will have also encountered a similar level of contamination and require the same attention.” 
In addition to cost savings from avoiding downtime, rejected materials and ground roll replacements, ITW Pillar says addition of the Maintenance Indicated technology will extend the ground roll warranty on ITW Pillar corona systems by one year. Maintenance Indicator technology is available for all new and existing corona systems.
