UV Curing Systems for Inks, Varnishes, and Adhesives

UV radiation heads from the ACS product line offer new UV curing options thanks to the cooling concept with no exhaust air. Their very compact construction allows for easy integration into almost any machine concept.
The use of ACS radiation head systems avoids the need for costly and complex air extraction components.
The radiation heads are cooled by a water cooling circuit without any intake or removal of external cooling air. In other words, no air-conditioned air is removed from the pressroom. The cooling concept of the ACS radiation heads ensures optimized operating conditions over the entire service life of UV lamps and UV reflectors. The closed air circuit protects the UV lamps and UV reflectors from contamination produced in the form of dust and printing ink by the printing machine.

Features
• No exhaust air, therefore
– no costly air intake and removal systems
– no contamination of expensive components
– no intake of expensive, air-conditioned pressroom air
– very high UV efficiency in a compact construction
• Narrow construction ensures a wide variety of installation possibilities
• Designed for all customary printing processes

Available as option
• Attachments and customized light screening devices on request
• Customized substructures on request
• Ozone extraction
• Doped UV lamps to extend the emission spectrum
• Ozone-free lamp design
• Options for additional reduction of substrate temperature (e.g. quartz guard plates with IR blocker function)

UV Curing Systems for Inks, Varnishes, and Adhesives

The DSK radiation head is a universal high-power UV radiation head for UV curing applications. Thanks to its compact shape and very high power output, it is suitable both for fitting in confined spaces and for complex curing applications at high irradiance levels.
The DSK is a closed system with high UV efficiency.
Filtered cooling air is drawn in through the radiation head and then extracted to the outside without interacting with the radiation zone. This protects the irradiated objects from contamination by particles and the cured formulation from impairment of surface quality. Cooling air is fed under temperature and power control to optimize power output and prolong the service life of reflectors and UV lamps, raising the efficiency of your UV process. The DSK is fitted as standard with a motor-driven shutter. It protects the radiation zone and substrate from undesirable escaping radiation during process stops. uviterno offers this high power UV radiation head in radiation lengths of 150, 250, and 350 mm.
Intermediate lengths are available by adapting one of the lengths.
