NUVA2 HP is the same NUVA2 cassette in a narrower format – the extra cooling available allows running up to 240W/cm, with maximum power decreasing as lamp length increases. Fully air-cooled, NUVA2 HP is available with a wide range of customisation options and is perfect for final cure inkjet applications (with iron-doped lamps) or high-speed web machines.
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 all replaceable components are plug and play for easiest maintenance.
Reliability is guaranteed and when powered by GEW’s RHINO system. NUVA2 HP can be purchased with a 5-year warranty which means no unplanned maintenance costs well beyond the return on investment period.
NUVA2 HP is ArcLED ready so that a NUVA2 HP 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.
- Highest power – Power up to 240W/cm and patented reflector design give extreme irradiance and dose levels for the most demanding applications
- Easy maintenance – A smooth action cassette design makes quick lamp changes possible in 2 minutes with just 1 hex key tool
- ArcLED flexibility – NUVA2 and LeoLED cassettes can fit in the same casing and run on the same power and control, for flexible hybrid press setups
- 5-year warranty – Safeguards against unplanned maintenance costs throughout ROI period
- Maximum machine productivity – Fast start lamp technology; system proactively avoids unplanned downtime; consistent, high-speed curing; quick to install
- Flexible options – Doped lamps (Fe, Ga); multi-point UV monitoring; inert gas and customisation to suit specialist applications

Watch our case study video
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 can now print and varnish substrates up to 2250mm wide with speeds up to 120m/min, mainly producing finish foils for wrapping and laminating on wood-based materials.
Managing director Christian Bungard explains: “On our previous system we certainly had issues with excessive heat radiation and the extremely short life cycles of the UV lamps. Our clients demand a quality product and expect us to be an absolutely dependable supplier. For this reason it was one of our main objectives to convert to a low maintenance operation with the highest reliability.”
