On the line, a lag in heating or a cold spot doesn’t just eat up time. It eats glass. Tempering lines stutter, bending radii wander, and lamination voids show up—then good sheets end up on the scrap pile. We built the Gathering Glass Infrared Heater to stop that kind of loss. What matters under the hood We run short-wave infrared emitters in a dense, modular array, tuned to how glass absorbs heat. It’s direct radiant energy that penetrates fast, with very little convection. Peak power hits in seconds, and the thermal field stays repeatable across the whole heating zone. Each module is 230/400 V, rated for continuous duty, and mounts with standard brackets and terminal blocks so integration is straightforward. The quartz envelope takes thermal shock, and the reflector geometry keeps the energy on the glass, not on the frame. Why it behaves the way it does on real work In tempering, the heater gets the surface to tempering temperature quickly, so you get the steep thermal gradient needed for consistent stress. In bending, the uniform profile cuts edge sag and keeps radii within tolerance. In EVA/SGP/PVB lamination, the controlled heat profile reduces bubbles and improves adhesion, which lowers rejects. Cycle times come down because the heater recovers instantly between loads, and energy use drops because the heat is only on when the glass is under the array. What you need to get right on install Installation is simple, but alignment is where people slip. Keep the array parallel to the glass path, and set the standoff distance within the specified window. Expect a bit more ambient heat near the module—plan ventilation and guarding accordingly. These heaters are optimized for glass; they perform best when the target is glass, not mixed loads. Set the temperature profile once, lock it in, and the line runs to spec, shift after shift.
