LeoLED UV Cassettes on a press

LeoLED Cassette

Transform the economics of UV… LeoLED is faster, greener and cheaper. It delivers more UV dose for your money than any other similar product currently available…

LeoLED Cassette

GEW’s LeoLED Cassette has a unique concept: deliver more UV dose for your money than any other product available. Over 5 years of product development and the latest LED technology combine to transform the economics of UV LED curing. Fully water-cooled, LeoLED provides over 35% more dose and 40% higher irradiance than GEW’s previous LED models.

No other product on the market enables you to print faster, whilst the cassette is designed to interchange with every current arc lamp model in GEW’s range. This ArcLED concept gives ultimate flexibility on press, and is also the cheapest route to upgrade any existing GEW UV system to LED – only the LED cassette and the chiller are required.

Like all our UV products, LeoLED 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.

Also available in our ‘Standard’ 40 x 100mm profile, LeoLED Cassette is perfect for web machines and can be manufactured up to 170cm, in 25mm increments. Where required, GEW can use more than one lamphead in tandem to cure any width.

Benefits of LeoLED Cassette

  • Faster curing – LeoLEDs 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.
  • Reduced energy consumption – Higher electrical efficiency of LEDs and instant on/off switching allow typical energy savings over 50% (versus a brand new UV Arc system).
  • Increased machine uptime – No moving parts for low maintenance and no warm-up/cool-down means less UV related downtime = better press productivity.
  • Longest LED warranty – LeoLED diodes are proven to run 40,000 hours*. GEW offers up to 5 years warranty irrespective of running hours.
    • *Lumen Maintenance Life Projection according to IES LM-80 and IES TM-21
  • No ozone, no mercury – GEW LEDs produce no ozone, so there are no air extraction requirements.

Watch our LED case study video

Watch our recent case study video from Etygraf in Spain. The company’s core production process is flexographic printing with low migration inks, with embellishments such as foiling, embossing, lamination and varnishing being used to add value.

The production team use GEW’s ArcLED hybrid UV curing system to run infrared, mercury arc and UV LED lampheads on the same press, enabling fast changeover of lamp configurations to suit each job. The competitive edge and cost savings created through the use of ArcLED are crucial to the business.

“With LED UV we now have less power consumption, less setup time, no changing of lamps… it’s faster to turn it on, it’s faster to turn it off. LED gives us a better competitive position in the market.”
