A system for curing a photosensitive coating on a moving substrate comprises a dual-fluid cooled reflector block and ultraviolet lamp assembly, first and second intermediate pressure blowers connected in series, a heat exchanger, refrigerating device connected in an appropriate manner to the reflector-block lamp assembly and a computer. The reflector block has a cavity with a reflective surface, a channel extending longitudinally of, and open to, the cavity for a substantial portion of its length and both an air and a water conduit extending longitudinally of the block. The lamp is mounted within the reflective block cavity and the air conduit connects through ports with the cavity channel. A temperature sensing device positioned within the reflector-block cavity continually monitors the temperature and transmits signals applicable thereto to a computer which is connected to the elements of the system to control their operation and the circulation of coolant water through the reflector-block and the passage of coolant air to and from such block channel and over the lamp to maintain it within a prescribed temperature range. |
