New reflector technology leads to increased efficiency
URS® reflectors: A new generation of cold mirror reflector technology.
At Drupa IST METZ GmbH will be showing its latest development in reflector technology, the URS® reflector. The URS® reflector will be shown on the booth as part of a laboratory unit. The new generation of so-called cold mirror reflectors is designed to increase the efficiency of the system significantly. Around 20% more UV energy reaches the substrate for the same electrical output compared to conventional reflectors. This results in an increase in production performance and a reduction in energy consumption.
The new URS® reflectors combine the advantages of the well-established aluminium and CMK (cold mirror) reflectors. Only the UV energy is reflected whilst the IR energy (heat) passes through the dichroic coatings and cold mirror glass into a water-cooled absorber profile where the heat is efficiently removed. Leading UV supplier, IST METZ, has carried out extensive field trials with different print processes such as offset, flexo, screen printing and letterpress. These showed that with the new reflector technology it is now possible to achieve production speeds with 160W/cm output lamps that were previously only possible with 200W/cm lamps. This offers benefits in terms of energy savings. Effective heat management is further ensured by a special absorber profile.
An additional advantage of the URS® technology is that the reflector geometry can be adapted to meet the exact requirements of specific production processes. Specific coatings can also be used for different applications. It is also easier to clean the reflectors and lamps as the new URS® reflectors are strong and easy to handle.
