UV Ray retrofits presses at Eurolabel in Italy, Skanem India

UV Ray has retrofitted presses at Eurolabel in Italy and Skanem India with new UV and water-cooled LED curing systems to boost energy efficiency and production performance.

UV Ray’s MaxLED curing systems were installed on Eurolabel’s Lombardi press on a chill drum with no extra drilling or path modification required. Overall improvements include stability due to water cooling of the LED and drum, as well as a higher chill temperature than original (22 deg C compared to 15 deg C).

It also saves energy with lower energy required from the chiller to keep the drum cooler. Curing also uses less than 20 percent of LED power with spare power available for more difficult colors to cure.

At Skanem India, their Bobst (Gidue) E-Combat 370mm press got an industry-first retrofit with UV Ray’s hybrid Atom UV and MaxLED curing systems. The retrofit was completed by Mayank Pandya of MNO Engineering and Oam Pandya of Lumen Engineering, representing UV Ray in India.

'We take pride in our extensive track record of successful hybrid LED UV system installations on industry-leading printing presses,' Pandya said. 'Our notable clientele includes Nilpeter, Monotech, Vinsak, Weigang, and AKO, demonstrating our commitment to delivering advanced and tailored solutions to a diverse range of clients.'

The hybrid LED and UV curing systems include eight LED (water-cooled) stations and two stations of conventional mercury arc UV technology (air-cooled with chill-base), all integrated into a sophisticated curing system ensuring long-term high performance and stable operation.

The advantages of an LED water-cooled system include operating at 25W/cm, stable output in any condition, low temperature transmitted to the press through the web, longer lifetime, and a sealed LED COB to avoid vapor contamination.

The system has standard features such as an IR filter and quick self-restrained water plug fittings, eliminating noise from a blower as no airflow is used from the ambience. 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.

'UV Ray srl stands at the forefront of the sustainability wave, asserting its leadership in the Indian market with a remarkable number of LED UV installations,' Pandya said. 'We excel in retrofitting, demonstrating a focused commitment to upgrading existing systems and processes with cutting-edge LED and UV technology.'
