Easy to Install

The high voltage transformer mounts directly to the station, and standard mounting brackets and lifting eyes make installation quick and easy.

Quick Start-Up

One of the biggest benefits of our unique drop-through design means that threading the web through the station is extremely easy and can be done in seconds This allows operators to quickly and easily switch products without slowing down or otherwise burdening production.

Durable

Our split box blown film station is designed with a number of features to maximize durability, including:

  • Electrodes are made of stainless steel to reduce contamination and makes them easy to clean

  • Sturdy Electrode supports enhance rigidity and eliminate sagging

  • Roll bearings are kept outside of the ozone environment, prolonging their life span

  • Roll bearings are enclosed to extend bearing life

  • A zero speed switch is included to automatically shut down the power supply in the event of low line speeds

Versatile

The treat width can be easily altered to enable lane treating using our stainless steel segmented electrode design in a removable electrode style, allowing you to customize the station to the needs of your application.

Safety

The split box blown film station includes a number of safety features such as:

  • Safety interlocks which automatically prevent operation if access covers are removed or the station is in the thread up position 

  • The electrode area is completely covered by aluminum panels

  • The built-in exhaust flanges easily connect to ozone exhaust blowers and destruct systems to protect from ozone emissions

    • Corona viewing above electrode or via side easy-view windows allowing for clear, unobstructed view and monitoring of corona discharge

    • Interlocked hinged access doors designed for customer safety allow quick access for adjusting electrode gap, pitch, and treat width

    • Easy electrode air gap adjustment via external adjustment screws at each end of the electrode

    • Easy electrode pitch adjustment at each support

    • Easy ground roll removal through the top of the treater station

    • Carbon ground brushes are used to provide direct electrical ground-protected bearings and ensure proper corona treatment

    • Easy drop through web thread up design

    • Standard segmented electrode

    • Zero speed switches to protect ground roll coverings

    • Mounted high voltage transformer simpifying customer installation

    • Carbon track resistant insulators out of direct exhaust are used to isolate electrodes from ground for harsh blown film environment
