Usually, it comes down to one annoying problem: the heat isn&rsquo;t hitting the glass evenly. If one side of your furnace is even 10°C hotter than the other, you&rsquo;re asking for trouble. You get <a href="https://o-yate.com">weird</a> internal stress, optical distortions, or—worst case—glass that just shatters for no apparent reason. The secret to fixing this isn&rsquo;t some magic trick. It&rsquo;s all about how consistent your infrared (IR) lamps are.</p> http://cozy-ir-heat.com/en/posts/tempered-glass-stress-removal/ Thu, 09 Jul 2026 12:04:55 +0800 http://cozy-ir-heat.com/en/posts/tempered-glass-stress-removal/ <p><img src="http://cozy-ir-heat.com/images/c147974466f1761700b8a23cd6bc5910.png" alt="Tempered glass stress removal"></p> <h2 id="building-infrared-heaters-that-actually-fit-your-3m-low-e-tempering-lines">Building Infrared Heaters That Actually Fit Your 3m+ Low-E Tempering Lines</h2> <p>When you&rsquo;re running wide-format Low-E tempering lines, the heat has to be exactly right—across the whole span. We don&rsquo;t just throw a bigger <a href="https://henruite.com">heater</a> 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.</p> <h3 id="power-and-size-designed-for-the-real-world">Power and size: designed for the real world</h3> <p>A heating zone that long needs serious muscle. That&rsquo;s why we spec <a href="https://goldisgood.com">these</a> 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&rsquo;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.</p>
