DELO Introduces Powerful UV Curing Lamp for Clean Rooms


DELOLUX 203 combines all the advantages of the classic DELOLUX 20 and allows the cooling profile to be chosen individually. (Figure: DELO)

DELO, one of the world’s leading manufacturers of industrial adhesives for automotive, consumer and industrial electronics applications, now offers a UV area curing lamp that can be used in clean rooms. The DELOLUX 203 UV area lamp features a modular design and can be adapted to customer-specific requirements. The lamp is based on DELO’s DELOLUX 20, but works with water cooling instead of air cooling.


Just as there is no single universal adhesive for every material, there is also no single universal curing solution either. The need for such solutions depends on several things, including the component size and/or the production environment. In the field of light curing, DELO not only offers a wide range of area and spot lamps that can be combined to suit differently sized irradiation areas, but it also offers variable cooling concepts tailored to customers' production conditions.

Designed specifically with clean rooms in mind

DELO has developed the DELOLUX 203 UV lamp, based on the company’s DELOLUX 20 lamp head, for a leading developer of equipment and process solutions for the semiconductor industry. The DELOLUX 203 UV lamp is designed for use in a clean room where there can be no influence on the continuous laminar air flow in the room. For this reason, DELO removed the original fan and replaced it with a new external cooling profile based on water cooling.

DELOLUX 203 has a wavelength of 365 nm. It weighs 1.6 kg without cooling module and measures 112 mm x 112 mm x 121 mm. The lamp provides an intensity of more than 600 mW/cm² and features plug-and-play connectivity for easy integration into production lines. The intensity progress is constant over the entire irradiation time.

“Just under a third of our adhesives are the result of customer-specific developments,” says Robert Saller, member of the DELO Management Board. “Our lamps can be optimally lined up with each other thanks to their thin edges at the light exit area, enabling homogeneous irradiation over the entire area. With the flexible cooling module, we can now respond even better to our customers' needs.”
