Getting the Voltage Right for Borosilicate Glass Heating
Working with borosilicate glass is a bit of a balancing act. If your heat isn’t pinpoint accurate, you’re looking at stress fractures—and nobody wants to deal with a shattered batch. That’s why we build infrared lamps that actually fit the reality of your factory floor, not some theoretical lab. The voltage headache Here’s the thing: off-the-shelf lamps are a gamble. Most of the time, they just don’t match your local grid or your machine’s transformer. If you accidentally plug a 230V lamp into a 480V circuit, it’s gone. Poof. Burned out instantly. On the flip side, if you under-volt, you just aren’t getting the heat density you need to do the job. We handle the boring math for you. Whether you need 110V, 480V, or 575V, we match the filament resistance to your specific power supply. You get the wattage you need, and your breakers stay happy. Built for the heat We use high-grade borosilicate or quartz for the envelopes because they can take a beating. They handle thermal shock way better than the cheap stuff. Inside, the tungsten filament is dialed in for whatever voltage you’re running. And if you’re using those high-voltage tubes (480V/575V), you get a nice little perk: higher power with lower current draw. That means you don’t have to run massive, bulky wiring through your heating banks. Making it work in the real world These are designed to be simple drop-in replacements. You swap them into your glass-forming or curing lines, and they just work. One quick tip, though. If you’re packing high-wattage lamps into a tight space, things get hot. Really hot. Just make sure your cooling fans are up to the task, otherwise, your sockets will start to degrade. The best part? Since we match the voltage exactly, you can ditch those clunky external step-down transformers. That’s a lot more breathing room on your shop floor.
