New economical Corona-Plus treaters for the extrusion market. To meet the increasing demands for up-to-date film extrusion machinery, Vetaphone has introduced a series of new economical Corona-Plus treaters for blown-film extrusion lines. VETAPHONE’s main features are their high quality module build equipment, with highly efficient generators. Also one of the latest innovations, the Quick Change electrode is very popular among the customers, as it makes maintenance and cleaning of the electrode extremely easy. Especially the TOU3 and TOW3 treater stations are very compact simple constructions, visually open for easy thread-up and adjustment of air gab. The TOU3 and TOW3 treaters can be configured for treatment over the entire web, skip or segmented treatment. Ozone is, due to the new design, extracted evenly along the whole electrode. Besides providing effective ozone removal, this also ensures efficient cooling of the backing rollers and extended lifetime on roller covering. Furthermore this efficient cooling provides consistent treatment across the web. Safety requirements are met by safety switches that disconnect the power when the electrodes pneumatically open. And again the work area is ozone-safe due to the efficient ozone removal.
