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

If you’re running a lehr wider than 3 meters, you know the struggle. Trying to get a perfectly even thermal profile across a massive sheet of glass is a nightmare. Standard, off-the-shelf lamps just can’t keep up. You end up with cold spots, and in this business, cold spots mean rejected glass. That’s why we build custom, continuous infrared units. We make them specifically to kill those cold spots once and for all.

On the line, glass moves fast—through tempering, bending, lamination, and coating drying. If the lehr heat isn’t steady, you start seeing stress fractures, optical distortion, and scrap piling up. Electric glass lehr heating is how we keep temperature control repeatable, shift after shift.

What matters technically

We build lehr heating around quartz short-wave infrared elements because they respond quickly and hold tight control. Power is matched to your process window, with voltage options and dense element layouts that give you a uniform thermal field across the glass surface. The payoff is predictable ramp rates and stable soak zones—exactly what you need when you’re running tempered safety glass, bent architectural units, or EVA/SGP/PVB lamination.
