Modular infrared heating array

On the glass line, heat is more than temperature. It’s timing, uniformity, and control. When the heating module starts to drift, you feel it immediately—bowed edges during bending, optical distortion in lamination, and thermal stress fractures that scrap tempered parts. We built a modular infrared array to stop those losses. It puts repeatable heat right where the glass needs it, with response fast enough to keep up with high-speed lines. What matters under the hood We run near-infrared (NIR) quartz emitters in a modular layout, so you can match the heating zone to the sheet without cooking the frame or the surrounding area. Each module draws 2.0–3.0 kW, delivering 25–35 kW/m² at the emitter surface—enough punch to drive energy into low-emissivity coated glass without leaning on convection. From ambient to 650°C takes 8–12 seconds, and the array holds ±2% temperature uniformity across the active field when measured at the glass plane. That tight distribution is what keeps bow and warp within tolerance during bending and keeps PVB/EVA flow consistent during lamination. Why it fits the process This array goes where traditional ovens can’t: right at the work, with heat that follows the conveyor. In tempering, it preheats consistently before the quench, which reduces edge stress and improves break pattern repeatability. In bending, zoned heat controls sag so the shape repeats sheet after sheet. In lamination, it brings the stack to tack-free quickly, cutting cycle time and keeping bubbles out. Energy use drops because you’re heating the glass, not the whole bay, and the modular layout lets you swap a single emitter block without shutting down the line. Here’s what to watch for The array is built for the plant, but it pays to be clean on install. Keep the quartz tubes free of dust and oil, and make sure your conveyor or fixture isn’t blocking the irradiance path—shadowing shows up as temperature deviation. For low-E coatings, match the emitter spectrum and spacing to the coating’s absorption; otherwise, you’ll chase uneven heating. The modules drop into most OEM frames, but double-check power and cooling connections before commissioning.
