Stop Dealing With Cold Spots in Your Glass Tunnel Kilns

Most infrared lamps stop at about a meter. That’s fine for small setups, but if you’re running an ultra-long glass tunnel kiln, those short lamps are a headache. You end up with “cold spots” wherever the lamps meet, and in glass work, a temperature dip is a recipe for disaster. We fix this by building custom quartz heating units that go well beyond 2 meters. No gaps. No cold spots. Just steady, continuous heat. The tricky part about going long You can’t just stretch out a tungsten filament and call it a day. The longer the lamp, the higher the electrical resistance gets. If you don’t account for that, you’ll hit a massive voltage drop and your heat will tank. To stop that from happening, we obsess over the filament diameter and the winding pitch. We match everything to your specific power supply so the heat stays dense and consistent. If you’re lining these up in a big array, we calibrate the wattage per centimeter. That way, the glass stays the same temperature from the moment it enters the tunnel until it leaves. Why we stick with high-purity quartz A 2-meter tube is a lot of material to manage. We use high-purity fused quartz because it actually handles the expansion and contraction of that length without cracking. For most glass projects, short-wave radiation is the way to go because it sinks into the material fast. But we give you options. Go with clear quartz if you want the maximum punch, or we can coat the quartz to shift it to mid-wave. That’s a lifesaver if you’re worried about scorching the surface of the glass. A few things to watch out for during install Here is the honest truth: these long units are powerful, but they’re also more delicate. We use heavy-duty connectors because the last thing you want is a burnout at the contact points. But once they’re in, you have to be careful. A 2-meter tube can actually sag under its own weight when it gets white-hot. You’ll need precision-aligned supports to keep everything straight. And one last tip: these things put out a massive amount of heat. If your kiln’s ventilation isn’t up to the task, you might accidentally bake your own control electronics. Double-check your airflow before you flip the switch.
