Air cooled UV LED systems

Air-cooled UV LED curing systems offer simple installation for curing and drying processes. Because no additional chillers are needed air-cooled solutions are usually less expensive and require less maintenance than water-cooled systems. To see the various power classes offered as well as wavelengths of our UV LED water-cooled curing systems, please see below.
