TREAT A VARIETY OF NONCONDUCTIVE SUBSTRATEs – RIGID AND FLEXIBLE

TNT Covered Roll Corona Treater

Carefully designed for blown and cast film applications, the TNT has quickly gained traction in the nonconductive space for its ability to treat these substrates with a proven 50% higher efficiency than conventional corona treaters.

A corona treater that works for you

With a robust and highly efficient design on the station, the power supply supports automatic self-operation with auto start/stop, constant rapid treatment monitoring and fault detection. The mechanical design of the station is built with an open frame and non-fixed assemblies to both protect your web and allow easy access for threading and maintenance. Choosing the TNT is choosing one less thing to worry about in your production line.

WHAT MAKES IT DIFFERENT

Key Features

PRECISION POWER

Closed-Loop PID Power Control

Real-time voltage and current feedback regulate output in a true closed-loop PID system. The generator maintains stable watt density regardless of line speed changes, substrate variations, or environmental conditions. Store treatment recipes and recall them for fast job changeovers with operator lockout to prevent unauthorized adjustments between shifts.

WEB PROTECTION

Counterweighted Electrode Assemblies

Electrode assemblies are counterweighted to lift away from the web when splices, knots, or imperfections pass through the treatment station. This protects both the web and the electrodes from damage, reducing downtime and extending electrode life. Easy access for cleaning, maintenance, and electrode replacement.

ultra-efficient corona discharge

High Density Corona

We allow the latest scientific findings to dictate our design. QC corona treaters can achieve higher dyne levels with cooler operation that leads to a longer operational lifespan.

BUILT TO LAST

Precision-Welded Steel Frame

A heavy-duty steel frame maximizes harmonic dampening and preserves alignment integrity over years of continuous operation. Stable web handling supports uniform discharge across the full treatment width. Every system is manufactured entirely in-house at our facility in Portage, Wisconsin: from welded frame to final assembly.

INTELLIGENT AUTOMATION

Smart Control

Line speed monitoring, frequency monitoring, auto/manual start, true kilowatt output, watt density control, kilowatt control, advanced digital fault log, spare parts list, and recipe programming with operator lockout. Fieldbus communication for integration with your line’s control system. Also available in analog control.

VERIFIED PERFORMANCE

Load-Tested Before Shipment

Every Advantage system is load-tested with material running through the station prior to shipment. Performance is verified under real operating conditions, not just bench-tested. When your treater arrives, it’s already proven.

Design
Applications

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.

empowered operators

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!

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.
