Getting Your Voltage Right in Glass Tempering
If you’ve ever dealt with cold spots on a sheet of glass or had a filament burn out way too early, you know the frustration. It usually comes down to one thing: the power isn’t matching the lamp. To get that perfect, uniform heat, you need your watt-density to be spot on. That’s why we build our infrared lamps to handle whatever your grid is throwing at them—whether that’s 110V, 480V, or 575V. You just spec out your line and we handle the rest. No guessing games.
Why the voltage actually matters
It’s not just about making sure the plug fits. The voltage actually changes how the filament is built. Think of it this way: when we jump up to 480V or 575V, we can push way more heat through the tube. But we do it without cranking up the current to a level that would melt your leads or fry your connectors. In the tempering world, consistency is everything. If you try to force a lamp into an array that it wasn’t built for, things go sideways. You’ll either end up with glass that isn’t tempered properly, or you’ll stress the quartz envelope until the lamp just gives up.
Making it fit your shop
We make drop-in replacements that just work. If your plant runs on North American 480V or that specialized industrial 575V, we wind the filaments to hit your exact wattage. Plus, when the voltage matches your power supply, you can ditch those bulky external step-down transformers. Your wiring gets cleaner, your control cabinet looks better, and you have fewer parts that can break.
A quick word on the trade-offs
Here’s the thing: high-voltage lamps are beasts when it comes to heat density, but they put more pressure on your insulation. You’ve got to make sure your sockets and wiring can actually handle the load. If you’re running 575V, don’t skimp on the cable shielding. You want everything tight and rated for that pressure so you aren’t dealing with arcing in the middle of a shift.
