SETT OCH ANORDNING VID HERDNING AV BELEGGNINGSMATERIAL MEDELST ULTRAVIOLETT STRALNING

摘要

Apparatus for photocuring a coating on a moving substrate in a system including a first and second tunnel with a treating chamber located therebetween and housing at least 1 mercury vapor lamp. The mercury vapor lamp has associated therewith a reflector module for directing UV light to the substrate. The reflector module temperature is controlled by physically spacing a liquid cooled heat sink from the reflector module so that only radiation heat transfer occurs therebetween.
