Brand-new corona treater rolls to your exact specifications: core material, diameter, face width, and covering type. Designed for your specific treater and application.
Send us your worn roll. We strip the existing covering, inspect the core, journals, and shafts, and apply a fresh coating, returning it to like-new condition at a fraction of the cost of a new roll.
Non-stick silicone elastomer sleeving that releases tacky materials and prevents wrap-ups. Available for rolls from 2″ to 10″ diameter. Quick replacement for covered roll systems.
Every recoat includes a full inspection of the roll core, shaft, and journals for wear and damage. If repairs are needed, we will let you know so that your roll comes back ready to run, not just recoated.
Our roll coverings are available in a wide variety of surface finishes and materials. Every roll is 100% corona treater tested prior to shipment—guaranteed performance with the strongest warranty on the market.
| CERAMIC COVERINGS | ||
| Conductive Ceramic | For bare roll systems. Protects aluminum rollers from surface oxidation and knife cuts while maintaining conductivity required for bare roll corona discharge. | Bare roll systems |
| Nonconductive Ceramic | The standard ceramic covering for covered roll applications. Prevents oxidation and knife cuts in a nonconductive formulation designed for covered roll corona discharge. Available for steel and aluminum roller cores. | Covered roll systems |
| High Dielectric Ceramic | High dielectric strength ceramic for demanding applications like skip treating where standard coverings break down. | Skip treating / harsh environments |
| Extreme Duty Ceramic | Maximum dielectric strength and high-temperature capability for the harshest corona treater environments. | Extreme duty / high temp |
| EPOXY | ||
| Epoxy | Ultra robust coating for heavy-duty operations requiring maximum durability. | Heavy duty |
| SILICONE | ||
| Silicone Coating | Applied directly to the roll surface for maximum durability and adhesion. More robust than sleeving with a longer service life. Non-stick release properties prevent wrap-ups. | Covered roll |
| Silicone Sleeving | Removable elastomer sleeve that slides over the roll. Quick to replace in the field without sending the roll out. Heat resistant to 400°F. FDA compliant. Diameters from 1.5″ to 10″. | Covered roll / quick replacement |
The right roll covering depends on your treater configuration, substrate, power level, and operating environment. Here’s a quick guide:
New roll or recoat? Give us the type of electrode and roll core, roll dimensions (face width × diameter), and current covering type. If you’re not sure, send us a photo and we’ll identify the station type and roll coating.
Our team recommends the right covering for your application and provides a quote. For recoats, we’ll assess whether your core is suitable for recovering or if a new roll is a better investment.
Every roll—brand-new or recoated—is 100% corona treater tested before it ships. You receive a roll that’s been proven under actual corona discharge conditions, not just visually inspected.
Tell us your roll dimensions and the type of electrode and ground roll. We’ll quote a new roll, a recoat, or both.
