GEW to present fully air-cooled LA1 UV LED curing lamphead at Labelexpo India 2016

LA1 is built around the same proven cassette-based design as the E2C and LW1 lampheads, and is fully compatible with existing ArcLED systems without the need for external chillers, pipes or coolant, or indeed any other modification.

Within an ArcLED system, printers are able to operate full hybrid UV curing, working with both mercury arc and LED lamp technology on the same press. Mercury arc cassettes and LED cassettes both use the same lamphead casing, the same power supply and air cooling ducts. The operator simply swaps the required cassette and the Rhino ArcLED power supply automatically recognises which type of cassette is installed in the machine, switches from low voltage DC power for the LEDs to high voltage AC for the arc lamps and changes the display on the Rhino touchscreen control accordingly.

Printing presses that operate with ArcLED technology can be upgraded from arc lamps to LED to benefit from both technologies with the same power supply, controls and cooling system.

GEW’s new multi-point in-line UV monitor consists of calibrated sensors positioned along the length of the UV lamp to measure the UV intensity in the curing system. It continuously reads and records the actual intensity across the full width of the lamp and calculates the UV energy dose on the substrate with precision. A dose monitor is set to alert the operator before the wrong dose could have an impact on production.

Other systems on display will include range of UV curing systems comprising mercury arc systems, LED systems and hybrid units alongside the fully hybrid Rhino ArcLED electronic power supply.
