Disclosed is a radiation apparatus for technical uses, especially a UV crosslinking apparatus of a printing press, coating machine, or similar. Said radiation apparatus comprises at least one radiation source emitting a processing radiation, at least one controllable and particularly wavelength-selective reflector which is assigned to the radiation source and is used for selectively directing the processing radiation onto a substrate that is to be processed or away therefrom, a driving mechanism which is effectively connected to the reflector, and a housing accommodating at least the at least one radiation source and the at least one reflector. At least one first and second radiation source are provided between which the controllable reflector is disposed and which can be operated above all in a separate manner. The reflector is formed and mounted so as to direct the processing radiation of all radiation sources towards the substrate in a first position while directing the processing radiation of all radiation sources away from the substrate in a second position.

Radiation apparatus

A dryer unit which is integrated as a module into a printed material guide system of a printing machine in order to facilitate two-sided drying of printed material is provided. The printed material guide system includes a guide surface which has a plurality of openings and an air system which is selectively operable in positive or negative pressure modes to assist the guiding of the printed material. The dryer module is arranged in an opening in the guide surface such that it heats at least one side of the printed material. At least one outlet opening is associated with the dryer module. The outlet opening is open into the plane of the guide surface and is coupled to a cooling system which is operable to provide cooling air to the dryer module.
