Getting Infrared Heat Right for Wide-Format Low-E Glass

If you’re preheating wide-format Low-E glass, you know the struggle. You need the heat to be dead-on across the whole width—no sagging, no weird spots, nothing. Once you cross that 3-meter mark, the standard lamps you find in a catalog just don’t cut it. That’s why we build custom continuous infrared units. We make sure every inch of that glass hits the right temperature before it ever touches the coating stage. The battle with voltage drop Here’s the thing: when you run a heating element over 3 meters, physics starts working against you. You deal with voltage drop and thermal expansion. If the voltage dips at the far end of the tube, you get cold spots. Simple as that. To stop that from happening, we use higher voltage configurations and heavy-gauge wiring. It ensures the power hitting the end of the line is exactly the same as the power at the start. Quartz and the stress of the job We stick with high-purity quartz for these long runs. Why? Because it handles thermal shock way better than your average glass. Depending on how deep that heat needs to soak into the substrate, we’ll use shortwave or medium-wave emitters. These tubes take a real beating from constant vibration and heating cycles. To keep the filaments from snapping the moment you flip the switch, we use reinforced end-caps and connectors that actually fit. The reality of the setup Putting this much heat into a 3-meter footprint isn’t a “plug and play” situation. It puts a massive load on your electrical panel. You’ll need to make sure your control cabinet can handle the high amperage these units draw, or you’re going to have a bad day. Plus, long lamps love to bow. To keep them perfectly straight and at the right distance from the glass, we tuck in rigid support brackets every 500mm. It keeps everything stable.
