ABSTRACT:
A radiator device for drying and/or hardening coatings of ink and/or varnish in a printing press, includes a high-power radiator having an electrode pair connected to an alternating-current voltage source, and a wall intermediate the pair of electrodes and defining a gas-filled discharge space, the wall being formed of dielectric material and being transparent to radiation generated in the discharge space, the wall of dielectric material being disposed in direct vicinity of one of the two electrodes, so that electrical energy capacitively injected from the one electrode into the discharge space causes additional discharges outside of the discharge space, the additional discharges having a catalytic effect on the drying and/or hardening process.
