UV Ray has retrofitted presses at Eurolabel in Italy and Skanem India, with new UV and water-cooled LED curing systems to enhance production performance and increase energy efficiency.
Eurolabel’s Lombardi press has been fitted with UV Ray’s MaxLED curing systems on a chill drum, giving a higher chill temperature of 22°C compared to the original 15°C.
According to UV Ray, additional benefits include the elimination of registration issues at any speed/power and with a range of substrates and colours; simple press startup with no colour vibration; easier repeatability from the straightforward control panel design; no register adjustment needed from start-up to production printing speed, and greater stability due to water cooling of the LED and drum.
With energy savings achieved from curing with LED and from the lower energy required from the chiller to keep the drum cooler, Eurolabel consequently has greater spare power available for curing more difficult colours.
At Skanem India, its Bobst (Gidue) E-Combat 370mm press received a retrofit with UV Ray’s hybrid Atom UV and MaxLED curing systems. The retrofit was completed by MNO Engineering and Lumen Engineering, representing UV Ray in India.
The hybrid LED and UV curing systems include eight LED water-cooled stations and two stations of mercury arc UV technology air-cooled with a chill-base, all integrated into a curing system to achieve long-term high performance and stable operation.
The system has standard features such as an IR filter and quick self-restrained water plug fittings, eliminating noise from a blower. The chiller, running the chill plates/base, keeps the web cooled and consumes less power than an air-cooled unit, which typically uses the power of a blower and AC cooling.
