higher treat levels

Extended Dwell Time

A 2″ wide aluminum electrode allows for extended dwell time in the corona discharge. Dwell time directly correlates to higher treatment levels. Achieve higher dyne levels with less power than conventional bare roll corona treaters.

Advanced Controls

Features like recipe programming, automatic air gap adjustment, watt density control, and straightforward directions makes operation a breeze.

cleaner components

Easy Access Assemblies

The electrode cover easily lifts to expose the entire assembly. Clean corona treaters perform better – we’ve made it easy to maintain optimized performance.

specially formulated coatings

Covered or Coated Ground Roll

The ground roll is covered with silicone sleeving, nonconductive ceramic coating, or epoxy coating. Ceramic and epoxy coatings offer extra durability and resistance to the rigors of 24/7 production (aka knives cutting the sleeving…)

application specific

Segmented Keys or Solid Aluminum

Depending on the application’s requirements, the electrode can be segmented to allow for varying widths and lane treating or, if customers are running set widths and treating the entire substrate, the electrode can be solid. Or, it can be a combination of both!

Recipe Programming


Input recipes for repetitive jobs and allow the treater to make the adjustments.

Big league

Performance

 

The covered ground roll and aluminum electrode work in tandem to deliver a powerful corona discharge. An extended dwell time in the 2″ corona discharge area allows more efficient and thorough corona treatment of your nonconductive materials.

Little league

Maintenance

 

With reduced downtime and simplified upkeep, our covered roll corona treater is not only a powerhouse in performance but also a champion in hassle-free maintenance. The perfect balance of excellence and ease of use.
