AeroLED and LeoLED are GEW’s latest advancements in UV LED curing for label and web printing. These innovative products share a common foundation, boasting the same core components and chassis design. Both are equipped with high-powered LED modules, a large window for maximum light extraction and curing power, and a double gasket design to protect the LEDs from dust and water ingress, simplifying maintenance and cleaning.
AeroLED is GEW’s air-cooled solution, capable of delivering up to 18W/cm² of UV LED output. With a fully air-cooled design, AeroLED is suitable for web printing applications up to 60 cm wide. The system features a quiet, centralised fan for cooling, eliminating the need for filter changes or noisy integrated fans and electronics on the press. Running at 53W/cm, AeroLED consumes 50 – 70% less energy than GEW’s industry-standard E2C arc lamp system. This energy efficiency translates into significant cost savings, potentially saving up to $50 – $84 per year for a typical printer with a 16-inch, 8-lamp machine, based on electricity prices at 20 to 25 cents per kilowatt hour.
LeoLED, on the other hand, is a water-cooled UV LED solution designed to meet the demands of more challenging applications. It offers a higher power level of up to 25W/cm², making it perfect for demanding print applications and running at high speeds exceeding 150 m/min. With a water-cooled heatsink and compatibility with GEW’s high-power 200W/cm E4C mercury lamp system, LeoLED provides exceptional performance and energy efficiency. Even at up to 88 W/cm, LeoLED can save 40 – 60% energy compared to an arc lamp system.
What sets GEW’s UV LED products apart is its ArcLED technology, offering unparalleled flexibility. By incorporating ArcLED, you can effortlessly switch between arc and LED cassettes within minutes on any station of your printing machine. The power supply and HMI take care of everything automatically, ensuring a seamless transition. For instance, you can equip ink stations 1 to 7 with LED cassettes while using arc lamp technology for the final varnish station. This versatile approach allows you to make the most of the cost-saving benefits of LED while catering to specific ink and process compatibility requirements.
It’s important to note that GEW’s UV systems, whether based on mercury vapour lamps or LED technology, operate on the advanced RHINO power supply platform. The RHINO platform encompasses RHINO and RHINO Lite (RLT) power supplies, along with GEW’s proprietary software and control systems. This standardised approach ensures that peripheral components remain consistent across the product range, making upgrades and compatibility seamless.
Most of GEW’s UV systems supplied since 2016 are already equipped for LED, so an upgrade only requires AeroLED cassettes and a software update. AeroLED is the quickest and most cost-effective route to LED printing.
