NUVA2

NUVA2

NUVA2 is the most effective UV curing system for wide web coating and specialist industrial applications. Fully air-cooled up to 250cm and available up to 27kW total lamp power, NUVA2 is available with a wide range of customisation and integration options.

GEW’s patented reflectors are actively cooled to ensure that heat transfer to the substrate is minimised, whilst delivering the highest UV intensity and dose available. The quick-change cassette design ensures fast lamp changes with only 1 hex key tool required and the innovative spherical lamp ends prevent breakages on long lamp changes.

Reliability is guaranteed and when powered by GEW’s RHINO system, NUVA2 can be purchased with a 5 year warranty which means no unplanned maintenance costs well beyond the return on investment period.

NUVA2 is ArcLED ready so that a NUVA2 and LeoLED cassette can be used interchangeably in the same print unit and existing NUVA2 systems can be cost-effectively upgraded in the field with only the LED cassette and chiller required.

Likora upgraded the final varnishing station on one of their gravure printing lines with a 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 installation is based on a Cerutti machine with 5 print stations using water-based inks with IR drying. The configuration is now able to print and varnish substrates up to 2250mm wide with speeds up to 120m/min and mainly produces finish foils intended for wrapping and laminating on wood-based materials.
