Zero Carbon Tracking

New electrode assemblies eliminate carbon tracking.


Watt density control

It’s 2024 – let the treater do the work for you.


Widths up to 5 meters

Confidently treat small to large variances in width.


Optimized airflow

Unique mechanical design with proprietary science.

Reliable Roll to roll

Patented Electrode Assembly

Achieving uniform treatment across the entire film surface is essential for quality and consistency. Our treater delivers precisely calibrated treatment, ensuring uniformity from edge to edge, roll after roll.

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.

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!

standard or custom

Mounting Brackets

Standard mounting brackets are provided with the system. We also supply custom mounting brackets for unique applications. Pictured are custom press rising brackets.
