Stop Wasting Power on Your Glass Annealing
Let’s be honest: glass annealing is an energy sink. Most shops are still relying on old resistive heaters that spend more time heating up the oven walls than actually treating the glass. It’s a waste of money and a waste of time. We build our long-life infrared (IR) tubes to fix exactly that. Instead of just warming the air, these tubes throw targeted radiant heat directly onto the glass surface. You get faster ramp-up times and a much lower power bill at the end of the cycle. The secret is in the heat density. When you swap out standard elements for our IR tubes, you’re changing the entire way heat moves through your oven. We use a precise tungsten filament inside high-purity quartz. The result? A tight, concentrated heat zone. No more worrying about those annoying “cold spots” that always seem to pop up in big annealing lehrs. Why do they actually last? People ask us why we call these “long life.” It comes down to the quartz grade and the gas we use. We use a halogen cycle that basically “recycles” the tungsten, pushing evaporated bits back onto the filament. It keeps the filament from thinning out and snapping. And we don’t make you rebuild your whole setup to use them. We can handle the voltage ratings to match your transformer or cut the tubes to a custom length to fit your specific oven. They just slide right in. A few things to watch out for… High-output IR tubes pack a punch, but they only work if your gear is up to the task. First, take a look at your reflectors. If they’re pitted or oxidized, you’re basically throwing 20-30% of your energy into the void. Clean them up or replace them. Also, you’ll want to double-check your PID controllers. Because these tubes hit the glass so effectively, your sensors need to be in the right spot. If they’re off, you might overshoot your annealing point and end up with thermal stress in your glass. Get the settings right, and you’ve got a much leaner, faster operation.
