The Superfici America Workpiece Pre-heater UMI pre-heating modular unit, is used to reach a precise surface temperature of the work-pieces before lacquering, thus achieving a better lacquer flow. The hood uses the IR irradiation to efficiently transfer heat onto the substrate to be lacquered. The hood can be fitted up with three, six or nine lamps according to the required temperature differential and to the line feed speed. The hood is generally installed onto cross bar conveyors.
