GEW UV LED Lamp Replacement

GEW UV LED Lamp Replacement

GEW supply a comprehensive range of UV LED systems for the coating, converting and wood coating industries.replacement gew uv lamp They are available for new machinery and can also be retrofitted to existing presses, breathing new life into older equipment. The systems offer a host of integrated accessories designed to maximise performance and deliver enhanced system functionality.

An applied voltage energises the sealed quartz tube, causing the mercury to vaporise into a plasma and release electrons.replacement gew uv lamp A proportion of these electrons strike cations in the gas mixture and transfer them to negative electrons, generating UV output and enabling current flow. The remainder of the ions are cooled by an integrated system of fans or chillers, and the UV radiation emitted is captured by a reflector. Pneumatic shutter mechanisms are always integrated into GEW electrode arc lamp assemblies to prevent heat generated in the quartz tube from degrading the shutter and reducing lamp lifespan.

Spectral profiles are readily available from UV system suppliers and provide formulators and end users with a visual representation of how the radiated energy from a specific lamp design is distributed across the electromagnetic spectrum.replacement gew uv lamp The exact combination of mercury, additive metals and inert gases along with lamp construction, cooling and curing system design all influence UV output.

A poorly maintained or dirty reflector can significantly reduce the amount of radiated UV that is incident on the cure surface.replacement gew uv lamp This can result in insufficient cure and reduced line speed. It is recommended that reflectors are cleaned at least every month and replaced on a regular basis to maintain maximum performance.

A GEW UV LED system provides the highest levels of electrical power, UV dose and irradiance to ensure an optimal UV curing process.replacement gew uv lamp This is especially important for narrow web applications, where the optimum balance of electrical power and UV irradiance is key to achieving a high level of disinfection in as short a time as possible.

The GEW UV LED portfolio comprises AeroLED2 and LeoLED2, both of which are optimised to operate without the need for a chiller, thus making UV LED more affordable to a wider range of users in the printing industry. In addition, they offer improved electrical power and UV irradiance specifications over their first generation counterparts, while maintaining compatibility with GEW’s patented interchangeable ArcLED system.

GEW’s application laboratory is specifically equipped to enable accurate testing of UV applications and to advise correct specification of GEW products. The facility utilises conveyor units, print proofing equipment and a full range of scientific measurement hardware to support customer test programs.

Using non-GEW supplied lamps in a GEW UV curing system is not recommended as it can damage critical power handling components and result in poor UV output and/or long lamp life. Using non-GEW supplied lamps may also invalidate any warranty still to run on a GEW system.
