Building Infrared Heaters That Keep Up With Your Glass Kiln
Let’s talk about heating up those massive glass tunnel kilns—the ones that stretch over two meters long. You need heat that’s steady, even, and never quits. The problem? A regular lamp just can’t reach that far. It leaves cold gaps, and that’s a disaster when you’re running glass. So we built something different: a custom infrared heater that runs the full length of the kiln, as one smooth unit. It fits right into the line and does the job without hot spots or cold zones.
Power, Voltage, and the Right Fit
At the heart of this setup is a long, high-power infrared lamp. We run it at high voltage—usually 400V—so the current stays manageable. That means you don’t need oversized wiring, and you don’t waste energy to line losses. We match the wattage to what your kiln actually needs, so the glass hits the target temperature every time, all the way through. And the length? That’s the key. We make lamps over 2 meters long, sized to match your kiln’s module pitch. One continuous heat zone. No gaps. No juggling multiple short lamps. Just clean, even coverage that’s easier to control.
The Materials That Make It Tough
We use a halogen-filled quartz tube. The halogen cycle keeps the filament clean, which means the output stays stable and the lamp lasts longer, even at the high temps glass work demands. The quartz handles thermal shock and stays clear for strong infrared output. For the electrical connection, we go with R7s-type connectors. They’re built for high heat and constant cycling. They lock in solid, and they make installation and replacement quick. Less downtime. More uptime.
What It Feels Like on the Line
In a glass tunnel kiln, the heat has to be smooth and predictable. Our continuous infrared unit gives you exactly that—uniform heat along the whole path the glass travels. That means less thermal stress, better quality, and fewer scrapped pieces. And because it responds fast, the system snaps to new setpoints quickly. You get tighter control over the process. Yes, it brings serious power density, so your kiln’s cooling and power setup need to be ready for it. But we build the unit to your exact length and power specs, so it drops right into what you already have. No fuss. Just heat—when you need it, where you need it.
