Segment electrodes (Standard)
Enables strips of corona to remain untreated in the running direction, to maintain the material weldability. Various minimum widths available.
Stainless-steel electrodes (Standard)
Suitable for an effective and homogeneous treatment of technical foils.
Electrodes pivoting in running direction
 This prevents the electrode system being damaged from inevitable impediments in the web material.
Electrode housing with metal enclosure
Lowest possible EMC levels, no fire-hazard, large high-voltage clearances ensure                that no flashovers or creepage discharges can occur through moisture or contamination when compared with electrodes using plastic shielding, long lifetime.
High-voltage transformer, mounted directly onto the electrode housing, no external high-voltage wiring
Avoids electric shocks, fires and interference radiation
Treatment and nip rolls (Order-specific)
Avoid slippage and reverse-side treatment
Silicone or ceramic dielectric
Spray-gap can be set from the outside
Ceramic high-voltage insulators
No danger of creepage discharges or incineration, unlike Teflon or other plastic material insulators. High degree of inherent safety.
