Ultraviolet light drying tunnel

room-temperature air blowerhot airscreen printing

Product overview
Beltrotherm is a pre-dryer conveyor designed for drying wet coatings after full-surface screen printing, suitable for both horizontal and vertical processes. Wet coatings are fed manually or automatically to the Beltrotherm. Depending on the drying program, evaporation and drying are controlled to enable adhesive-free further processing. For double-sided printing, boards or substrates are transported contact-free on V-belt drive and dried precisely as they pass through the evaporation and drying zones.
