Getting Your Glass Tunnel Heat Exactly Right

If you’ve ever worked with glass tunnel kilns, you know the struggle of keeping the temperature steady over a huge distance. It’s a pain. When you’re moving ultra-long sheets of glass, those standard short-lamp setups usually leave “cold spots” right at the joints. It ruins the consistency. To fix this, we build continuous infrared heating units that stretch over 2 meters. No gaps. Just steady heat. The trick to long-form tubes You can’t just take a standard lamp and stretch it out. If you do, the quartz will sag or just burn out right in the middle. It’s a mess. We spend a lot of time balancing the wattage and voltage so the heat stays even from end to end. Instead of a choppy pattern of hot and cold zones, you get a smooth “thermal curtain.” It just works. Built to actually last We use high-purity quartz because, well, these things get incredibly hot. But here’s the real challenge: a 2-meter tube is a magnet for vibration and mechanical stress. To stop the lamps from snapping when the kiln expands or contracts, we add specialized support brackets. We also set up the wiring for a continuous layout. This means you can install them back-to-back without leaving any dead zones in your heating area. The honest trade-offs Here is the upside: fewer connectors and way less wiring. Fewer joints mean fewer things that can break. But let’s be real—there’s a catch. A 2-meter element is more fragile than a bunch of small 500mm lamps. If one tube goes, you’re replacing a bigger section. You also have to watch your power supply. If the voltage drops across a long line, the far end of your kiln will be colder than the start. To keep things stable, we suggest using dedicated circuitry for each bank of long units. It’s the only way to make sure the output stays where it needs to be.
