The Split Box is an economical system primarily used in the cast and blown film extrusion industries. The corona treater design promotes ease of thread-up along with an industry first with a sophisticated break away electrode design.
Standard mounting brackets and lifting eyes make installation quick and easy. The high voltage transformer is mounted directly to the station with all high voltage connections factory wired and tested.
The easy-thread, “drop through” design enables operators to thread the web through the station in seconds.
- Stainless steel electrodes for reduced contamination and easy cleaning.
- In order to protect the treater rolls, a zero speed switch automatically shuts down the power supply when the web achieves low line speeds.
- Roll bearings are outside of ozone environment to prolong bearing life.
- Easy view windows allow clear unobstructed view of corona discharge.
- Electrodes are provided with optimal support to enhance rigidity and eliminate sagging.
With Pillar’s stainless steel segmented electrode design and removable electrode styles, users can alter the treat width or lane treat according to application.
- Safety interlocks prevent operation of power supply if access covers are removed or if station is in the thread-up position.
- Electrode area is completely covered by lightweight aluminum panels.
- Built-in exhaust flanges allow for easy connection to ozone exhaust blowers or ozone destruct systems to protect the plant environment from ozone emissions.
- Pressure switch proves exhaust airflow to assure maximum ozone evacuation.
Additional Features Include
- Easy roll removal through top of station
- Air gap adjustment: two external adjustment screws at both ends of the electrodes
- Easy electrode pitch and gap adjust
- Carbon ground brushes are used to provide electrical ground around roll bearings
- Zero speed switches prevent power supply from running if either roll should stop or rotate below the preset level
- Mounted high voltage transformer
- Slide gate balance dampers are located at each exhaust manifold and used to assist in exhaust airflow management
- All metric hardware Film Extrusion
- Interlocked hinged access doors
