Getting the Voltage Right for Glass Stress Relief

If you’ve ever dealt with glass annealing, you know the stakes. One wrong move with your thermal profile and you’ve got a sheet of glass that decides to shatter for no apparent reason. It’s a nightmare. But when you’re setting up an infrared system for a global line, the heat isn’t actually the hardest part. The real headache? The power grid.

Dealing with the Grid

We build our IR lamps to hit specific targets—usually 110V, 480V, or 575V. Now, this isn’t just about getting the lamp to glow. It’s about how much current you’re pulling. If you go with a 110V lamp at high wattage, you’re looking at heavy-gauge wiring just to stop the voltage from dropping. It’s bulky and a pain to install. Switching to 480V or 575V changes the game. You can move the same amount of energy using much thinner wires, which means your electrical panels don’t have to be the size of a refrigerator. And here is the thing: if you’re plugging into a standard US or Canadian industrial grid, you want a lamp that matches your transformer output exactly. Adding a transformer just to step the voltage down is just adding another part that can break. Plus, it wastes power. We just wind the filament to match your site’s voltage from the start. Simple.
