GEW launches NUVA2 UV system for wide web applications

The NUVA2 is a fully air-cooled UV system for web or sheet-fed applications in the printing, coating and converting industries. The active air cooling and optically tuned reflectors maximize lamp curing effect while reducing heat radiation onto the substrate.

NUVA2 systems can at a later stage easily be upgraded to LED operation. An arc lamp cassette and an LED cassette can be operated interchangeably and seamlessly on the same print unit using the same Rhino ArcLED electronic power supply, control panel and cabling – the only tool needed is an Allen key.

GEW is also using drupa 2016 to unveil the Multipoint in-line UV dose control, which allows comprehensive monitoring of the UV output during the curing process. It acts as a built-in UV intensity meter and measures the actual intensity across the full width of the lamp. Low intensity which would not adequately cure is thus avoided, as is insufficient output from a degraded lamp.

GEW’s third launch is an inert atmosphere UV curing system, used principally in the production of silicone release liners and direct food contact packaging, with the curing process takes place under controlled conditions in a sealed nitrogen chamber. GEW’s inert atmosphere curing system can be supplied as an add-on or as a retrofit and comes with an embedded oxygen level analyser to ensure process consistency and production efficiency. German printer Bizerba has installed an MPS EF4 featuring nitrogen-inerted UV curing technology from GEW to boost its production capacity and overall efficiency.
