Building Infrared Heaters That Actually Fit Your 3m+ Low-E Tempering Lines
When you’re running wide-format Low-E tempering lines, the heat has to be exactly right—across the whole span. We don’t just throw a bigger heater at the problem. We build units that match the scale of the line, so you get a smooth, even heat profile over glass that stretches past three meters.
Power and size: designed for the real world
A heating zone that long needs serious muscle. That’s why we spec these units for 400V operation—so the power can run the full length without voltage dropping or circuits getting overloaded. The wattage is tuned to your line speed and the glass thickness, so the temperature lands where you need it, when you need it. And here’s the key: we build the heater as one continuous element, not a patchwork of modules. No cold spots. No weak seams. The length matches the oven, and the footprint lines up with the conveyor width, so the heat lands exactly where it should. One thing to keep in mind: with high power density over that distance, the surrounding equipment feels the heat. Plan for it. Your cooling and thermal management need to be ready for the ambient rise.
The materials that make it work
We use quartz tubes because they respond fast and stay stable at high temperatures. Inside, the filament layout is arranged to spread the radiation evenly—critical when you’re trying to remove stress consistently across the entire width. The surface gets a specialized coating, tuned to match how Low-E glass absorbs energy. That means better energy transfer, less wasted heat, and a cleaner, more efficient process. For the electrical side, we use R7s or SK15 connectors. They’re built for high current and high heat, and they hold up through repeated thermal cycling without loosening or arcing. It’s the kind of detail that keeps things running smoothly, day after day.
What this means on the line
On the tempering line, this heater handles the preheat before quenching. The uniform heat ensures the glass hits a consistent temperature, so the stress distribution stays even. That’s the kind of precision that prevents headaches later. Because it’s a single-unit build, installation is simpler. Fewer joints to manage. Fewer places for something to go wrong. Less downtime just to get set up. For your engineers, that means repeatable thermal performance, easier integration into existing lines, and far fewer hot spots that can throw off tempering. It’s a design built around the reality of wide-format Low-E glass—delivering the right heat, right where you need it.
