Generator 8002

The twin generators of the 8002 series represent a new generation of corona generators for the medium to high power segment. The generators are characterized by their robust, user friendly, and easy to maintain stand alone design as well as various innovative hard and software features. In combination with a corona treating station, material surfaces are functionalised to guarantee adhesion in many converting applications.

Two independently adjustable power out-puts make the 8002 series especially suitable for double side treatments and skip treatments in high speed printing presses.
