System LeoLED2®
LeoLED2 takes LED performance to new heights over GEW’s already highly-acclaimed, water-cooled LeoLED system. Offering a 55% increase in electrical power (140W / cm), a 50% increase in UV dose (300mJ / cm²) and a 45% increase in UV irradiance (44W / cm²) compared to its predecessor, LeoLED2 is GEW’s next generation UV LED curing system that guarantees the best performance on the market for the most challenging curing applications.
As with the generation 1 model, LeoLED2 is available in both a cassette version and a compact version, depending on the requirements of the customer, their equipment and their application. Both models are designed to interchange with every current arc lamp model in GEW’s range. This patented ArcLED technology gives ultimate flexibility on press, no matter the application.
Like all our UV products, LeoLED2 is powered by GEW’s RHINO power supply for ultimate reliability and controlled by RHINO Control which comes as standard with IoT remote monitoring. This allows our customers the flexibility to go ArcLED without having to invest in a whole new, independent system. For customers with a GEW arc system installed, an upgrade can be as simple as adding a chiller, a UV LED lamphead, and running an upgrade.
LeoLED2 also comes in two power level options, offering ultimate customisability to customers, depending on their application and energy saving needs, whilst providing faster printing speeds alongside GEW’s renowned process reliability.

Benefits of LeoLED2
- Reduced energy consumption – Higher electrical efficiency of LEDs and purity of UV output allow typical energy savings of over 65%, compared to a mercury UV system of similar specification.
- No ozone, mercury-free – GEW LEDs produce no ozone and contain no mercury, so there are no air extraction requirements.
- 5 year warranty available – LeoLED2 diodes have an expected lifetime of over 40,000 hours. Warranties are available for up to 5 years, irrespective of running hours.
- Turnkey solutions – GEW deliver a complete integrated UV curing solution; including lampheads, cooling equipment, power supply and control systems.
- Faster curing – LeoLED2s industry-leading dose output supports the market’s fastest printing speeds.
- Print without limitations – Unsupported films, shrink sleeves and other delicate materials can be processed without heat damage.
- Increased machine uptime – No moving parts for low maintenance and no warm-up/cool-down means less UV related downtime = better press productivity.

Patented interchangeable ArcLED technology
ArcLED hybrid UV technology allows interchanging of a UV Arc lamp or LED array in the same housing.
Optimise your press with a mixture of Arc and LED curing on any station, for the ultimate flexibility.
GEW have held granted patents covering this technology internationally since 2016.
The video below illustrates how GEW’s LeoLED2 would function as part of our ArcLED technology on a sheetfed offset press, although the same functionality is available across other printing applications.
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.
