System 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.

RHINO Power supply
Fail-safe operation
Military-grade design protects the UV system from damage caused by incorrect voltage, short-to-ground, dropped phases, mains spikes and lightning strikes. In the event of a serious mains disruption, the system powers down in a safe mode. RHINO is designed to run in the harshest conditions and at ambient temperatures of up to 40°C. The system is unaffected by dust, ink mist and other contaminants.
Lowest operating costs
With intelligent power management the current draw is balanced and harmonic distortion is minimised, reducing energy demand.
Minimal footprint RHINO Rack
A compact cabinet houses power supplies for up to 6 lamps and provides perfect cooling, atmospheric protection and mains power distribution.
5-year warranty available
Using GEW’s embedded service package gives total confidence in the reliability of GEW power electronics and minimises unplanned maintenance costs. GEW is the only UV supplier to offer this level of warranty.

System performance reports
Regular reports are generated, detailing energy usage, uptime percentage and system performance. The Event Log continually records system use and operating parameters, ensuring the system is working at peak efficiency at all times.
Energy performance measurement
The RHINO control automatically logs energy use and displays it on screen at the touch of a button, showing kWh consumption in operation, at idle and % production uptime.
