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 heat that stays consistent all the way to the edges. But once you cross that 3-meter mark, the standard lamps you buy off a shelf just stop working. They can’t keep up. That’s where we come in. We build custom, ultra-long infrared heating units specifically for those massive annealing tunnels.

The Headache of 3-Meter Arrays

Building a heater this long isn’t as simple as just adding more lamps. You run into real-world problems—like voltage drop and thermal expansion. If you just string lamps together, you’ll end up with a nightmare: the center of your glass gets scorched while the edges stay cold. We fix that by tweaking the wattage density across the quartz tube. It keeps the temperature flat and predictable. Then there’s the “sag.” When these tubes get hot, they want to bow under their own weight. We use reinforced quartz supports to keep everything straight and locked in place.

Introduction

We build industrial glass preheating systems that go way beyond a single infrared lamp. Think of them as fully integrated heating modules for bending—ready to roll right onto your factory floor. The whole point? To get precise, high-density infrared heat exactly where you need it—without the headache of piecing together a custom setup.

The Power Behind the Heat

At the heart of these systems are high-voltage infrared heating elements, usually running at 400V. That voltage delivers the power density needed to crank up glass temperature fast. A 300mm tube rated at 2500W means concentrated energy in a small space—so preheating cycles get shorter. Plus, that voltage choice keeps wiring simpler and cuts down on line losses. But here’s the catch: all that power generates heat. So you’ve got to make sure your cooling system can handle it. If it can’t, the lamp life takes a hit.
