Substrate Cooling
Controlling temperature is critical for many applications. GEW’s array of cooling options ensures even the most powerful UV systems do not damage substrates.
The UV curing process is energy-intensive and causes both direct and indirect heating of the target substrate, which in the majority of cases needs to be controlled. For safety reasons, some form of barrier behind the target substrate to shield off and dissipate stray radiation from the lamp is essential for protecting the machine and its operators. The three most common methods of substrate cooling that meet both of these requirements are:
Air cooled heatsinks
Water cooled heatsinks
Water cooled chill rollers
Where roll material is being processed, the most common solution for this is an extruded aluminium heatsink plate. GEW have a very neat solution for this which is integral to the UV lamphead and can be either air or water cooled, depending on the application. For the majority of processes this method is very effective, unless very heat sensitive materials are being used.

UV Lamp Curing Systems
Mercury lamp systems are an efficient, long-established UV light source for industrial processes and they are still growing in use today.
GEW’s UV lamp curing systems use medium pressure mercury vapour lamps as the UV light source. Depending on power level, length of lamp and form factor required, GEW have various lamp systems with different cooling methods to meet a vast array of UV irradiation applications.

E2C HP
High powered variant of GEW’s E2C lamphead, designed for low migration and/or high-speed print applications.
E2C HP comprises a standard E2C UV lamp cassette housed in a larger casing to enable more air cooling and thus higher running power, up to 180W/cm. Perfect for low migration or high speed print applications up to 80cm wide, it boasts the same reliability and patented reflector designs contained in GEW’s most popular E2C product.
E2C HP still supports printing on the widest range of heat-sensitive materials because our actively air-cooled reflectors reduce heat transfer to the substrate. It also boasts GEW’s famous quick-change cassette design enabling a new lamp to be fitted in under 2 minutes with only 1 hex key tool required.

UV LED Curing Systems
UV LED systems are the future of UV curing. GEW’s LED products are unmatched in performance and value throughout the industry…
GEW’s UV LED curing systems use ultraviolet light-emitting diodes (UV LEDs) as the primary light source. Tens or even hundreds of UV LEDs are built onto GEW’s highly specialised circuit boards − named LED modules. Multiple LED modules are mounted together to create a light array which can vary from 15cm to 250cm in length. GEW offers different UV LED product form factors, power levels and wavelength ranges to satisfy many different application requirements.
