ABSTRACT:
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.
The method of the invention comprises controlling the temperature of the reflector surface so that the surface is always at a temperature at least as high as the temperature of the coating to be cured.
