The Headache of 2-Meter+ Infrared Units for Glass

Most infrared lamps stop at a meter. That’s fine for small jobs, but when you’re running a massive glass tunnel kiln, you hit a wall. You can’t just line up a few short lamps and hope for the best. If you do, you’ll end up with cold spots right at the joints. It’s a nightmare for consistency. That’s why we build custom continuous units that push past the 2-meter mark. The Power Struggle Here’s the thing about long spans: voltage is tricky. If you try to run a standard 230V circuit over two meters or more, you’re asking for trouble. You’ll either deal with voltage drops or you’ll trip your breakers constantly. We usually switch to higher voltage or mess with the parallel wiring. Why? Because we need the wattage density to be exactly the same from the first centimeter to the very last. If that power fluctuates even a little, your glass warps. And nobody wants to scrap a whole batch because of a power dip. Fighting Gravity and Heat A two-meter quartz tube is essentially a giant, fragile noodle. Once it hits operating temperature, it wants to sag. If that tube bows and touches the reflector, you’re in trouble. You get a hot spot, and then—snap—the glass cracks or the filament burns out. To stop that, we use reinforced brackets and get really obsessive about the spacing. We use high-purity quartz to handle the thermal shock, but you still have to be smart. Your conveyor speed needs to be perfectly in sync with how these long units ramp up. The Cooling Catch These long units put out an incredible amount of radiant energy. The glass gets the heat it needs, sure, but the housing takes a beating. You can’t just ignore the cooling side of things. If your fans aren’t strong enough to pull the heat away from the wiring and reflectors, your insulation will just crumble. Then your connectors fail, and the whole system goes dark. It’s all a balancing act. You want the heat, but you have to give that heat a way out.
