Ultra-wide UV video from GEW
A new video has been released by GEW to illustrate how wide-web converters can benefit from GEW’s fully air-cooled NUVA2 UV systems. The NUVA2 lamphead is available in widths of up to 2.50m and boasts particularly fast switch-on and cool-down cycles achieving considerable electricity and time savings.
It addresses the specific requirements of converters who need to coat substrates in extreme widths.
Likora in Germany upgraded the final varnishing station on one of their gravure printing lines with the new UV-curing system replacing an older system. To this purpose they integrated three GEW-made 240cm-wide NUVA2 UV lampheads with RHINO power supply.
The three UV lampheads are positioned vertically one after the other so as to achieve the maximum UV-curing effect. The UV system is mounted in a custom designed aluminium frame that integrates a retractable cooling panel and water-cooled quartz window to prevent the heat transfer onto the substrate.
The configuration is now able to print and varnish substrates up to 2,350mm wide with speeds up to 120m/min and mainly produces finish foils intended for wrapping and laminating on wood-based materials.
