Fixing the “Cold Edge” Problem in Wide-Format Low-E Preheating

If you’re preheating Low-E glass and your sheets are wider than 3 meters, you’ve probably noticed a frustrating pattern: the middle is hot, but the edges are lagging. It’s a common headache. Standard lamps just aren’t built for that kind of scale, and those cold spots can ruin a whole batch. That’s why we build custom continuous infrared units. No gaps. No guessing.

The struggle with 3+ meters

You can’t just “stretch” a lamp to make it longer. If you do, you run into physics problems—voltage drops and quartz tubes that can’t handle the stress. We handle this by obsessing over the linear power density. Basically, we tweak the wattage and voltage so the heat stays steady from one end to the other. One thing to keep in mind: these high-wattage units pull a lot of juice, especially during that first cold-start surge. You’ll want to make sure your electrical bus can take the hit. We balance the ohms on our end so you don’t have to worry about the heat dipping at the edges.
