Application:
The laboratory device can treat one side of electrically conductive foils or plates of any wall thickness and
non-conductive foils (polymer materials) and plates up to a wall thickness of around 2mm. Hand roll
electrodes with various web widths are available for the pre-treatment. The material which is to be treated
is placed on the earthed base plate before being rolled over with the hand roll electrode. The discharge
takes place between both of the electrodes on the surface of the material. Moulded parts can also be
treated after the hand roll electrode has been replaced with a rigid electrode which can be blank or
insulated.

Design:
The device comprises a semi-conductor generator with an integrated transformer for high-voltage
generation, the hand roll electrode (standard working width 200mm), the earthed ground plate (standard
dimension 400 x 400mm), power cable and a hand or foot-operated switch for the activation of the Corona
discharge. The output (intensity of the Corona discharge) can be adjusted at a potentiometer and read off a
display. The hand roll electrode is fitted with an ozone suction connection which can also be used to feed the
process gas.
