Stop Wasting Power on Your Glass Annealing
Let’s be honest: annealing is usually the biggest energy hog in the entire production line. Most old-school heating setups spend way too much time heating up the air around the glass instead of actually heating the glass itself. It’s a waste of money. We handle this differently. By using shortwave infrared (IR) lamps, we aim the heat directly at the material. It cuts out that annoying thermal lag and, more importantly, knocks a decent chunk off your annual power bill.
How the heating actually works
Here is the secret: shortwave radiation doesn’t just sit on the surface; it actually penetrates the glass. Because of that, you hit your annealing temperature much faster. We design these lamps to pack a ton of heat into a tiny footprint. You get a rapid ramp-up, which means you’re using fewer kilowatt-hours every single cycle. It’s just more efficient.
The gear and getting it installed
We use high-purity quartz tubes because they can handle the shock of rapid heating and cooling without cracking. Depending on how fast your line moves, we can tweak the wattage and voltage to fit whatever electrical panels you already have. In most cases, you can just drop these into your existing supports. No need to rip everything out and start over. One quick tip: we use industrial-grade connectors so you don’t have to worry about arcing or burnt terminals when things get hot. Just make sure your wiring gauge is right for your voltage. These tubes put out a massive amount of heat, so if your housing isn’t vented properly, your cooling fans are going to feel the strain.
What this does for your bottom line
When you switch to IR support heaters, you don’t need as much “soak time.” You can move your glass through the Lehr faster. That does two things. It saves you electricity, and it lets you push more product through the door. The only catch? You have to be precise with where you put the lamps. If they’re off-center, you’ll end up with uneven heat across the glass sheet. But once you get the alignment dialed in, you’ll see the savings hit your meter almost immediately.
