TwinRay from AdPhos: UV curing for sensitive substrates

Developed specifically to overcome the problems of UV curing on plastics and other heat sensitive substrates, TwinRay from AdPhos AG, supplier of accelerated drying systems and owner of Eltosch, is a new indirect radiating UV module.

In a new concept for UV curing, a triangular rotary reflector reflects UV radiation from a dual lamp system on to the substrate. By using only indirect UV energy, TwinRay eliminates practically all heat radiation, leaving only pure UV and visible light remaining. 

TwinRay delivers efficient, high-power curing up to 240W/cm, whilst eliminating heat-related issues such as wavy sheets, high pile temperatures, registration problems and stacking, plus the press and its surrounding environment remain cooler than with standard UV or other drying technologies.

The unique, dual-emitter design enables standard and speciality lamps to be used side-by-side in the same unit, ensuring optimum cure and extending the process potential.  For example, a WhiteCure lamp can be used for depth cure of opaque white inks with a standard lamp for surface cure. 

Service and maintenance of TwinRay modules is simple.  The design includes replaceable ‘easy change’ dichroic reflector inserts and tool-free technology ensures that the plug-in lamps can be changed in as little as 30 seconds.
