Stop Paying to Heat the Air
If you run a tempering line, you already know that glass annealing is where your power bill goes to die. It’s a massive energy sink. Most setups waste a ton of heat just trying to warm up the air inside the oven. We do things differently. We use shortwave infrared (IR) lamps that hit the glass surface directly. No waiting around for the air to get hot. The heat just jumps straight from the lamp to the glass. Getting to the softening point, fast The goal here is high power density. We want to hit that softening point quickly. Because we use the shortwave spectrum, the heat sinks into the glass almost instantly. It’s fast. Really fast. That means your ramp-up time shrinks, your cycle times drop, and you stop burning through kWh for every single piece you produce. Plus, we build these lamps to take a beating. They can handle the non-stop grind of a continuous bending line without the filaments giving up on you. The gear under the hood We use high-purity quartz envelopes because they let the IR light pass through without blocking it. We also tune the filaments to match your specific voltage. This is a big deal because it means you probably won’t have to spend a fortune on new transformers. The best part? These are basically drop-in replacements. If you have aging resistive elements, you can swap them out, wire them into your current controllers, and you’re good to go. You’ll notice the difference immediately—heat transfer that used to take minutes now happens in seconds. One thing to watch out for Here’s the catch: these lamps put out a massive amount of heat. That puts a lot of pressure on your reflectors. If your reflectors are pitted, dirty, or oxidized, you’re basically throwing energy away. That heat bounces off the glass and gets absorbed by the oven walls instead. To actually keep your costs down, you’ve got to keep those surfaces polished. At the end of the day, it’s about cutting the waste. When you stop paying to heat the air and start paying to heat the glass, that’s when you’ll actually see your electricity bill drop.
