Stop Wasting Money Heating Your Entire Factory
Let’s be honest: glass annealing is usually the biggest energy hog in the whole production line. It’s frustrating. Most ovens just blast heat everywhere, warming up the air and the walls, while the glass only takes in a fraction of it. We figured there was a better way. Instead of heating the whole room, our infrared lamps put the heat exactly where it belongs—right into the glass. Getting the heat where it matters We use shortwave IR because it actually sinks deep into the substrate. It doesn’t just sit on the surface. The cool part? You can tweak the wattage and voltage to match how fast your conveyor is moving. This keeps your temperature steady and predictable. If you go with high-wattage tubes, you can actually shrink the size of your annealing lehr, which frees up some much-needed floor space. One heads-up, though: when you’re pushing that much heat, your reflectors take a beating. Keep them clean. If they get grimey, you’ll end up with hotspots and wasted power. Built to take a beating We use high-purity quartz for the envelopes. Why? Because rapid cycling creates a lot of thermal shock, and cheap materials just crack. We can also add special coatings to the lamps. This stops the energy from bouncing off the glass and forces it to be absorbed. And don’t worry about a massive electrical overhaul. We use standard industrial connectors, so these are basically “plug and play.” You can swap your old setup for these without having to rip apart your electrical panels. What this actually does for your power bill If you’re still using resistive heating elements, you know the pain of waiting hours for the oven to warm up. You’re paying for “idle heat” before you’ve even processed a single piece of glass. With IR lamps, that wait drops from hours to minutes. You’re targeting the workpiece directly, which slashes your annual electricity spend. Just make sure your lamp pulsing is synced up with your feed rate. If your sensors are off, you’ll overshoot the annealing point—and that’s just throwing money away.
