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.
