Let’s talk about the 635mm 800W Quartz Halogen Heater
If you’ve ever dealt with uneven heating in a drying tunnel, you know how frustrating those “cold spots” are. They ruin the finish and slow everything down. That’s exactly why we built this lamp. We wanted something that puts out a steady, linear line of heat without the guesswork. The specs are straightforward: 635mm long, 220V, and 800W. It’s a sweet spot. You get plenty of power, but it’s stable enough that you won’t burn out the filament the moment you start cycling it on and off. Plus, since it runs on 220V, it plugs right into most industrial grids. No need to mess around with bulky, expensive transformers. But the real secret is in the glass. We use high-purity quartz because it doesn’t freak out when the temperature jumps. Borosilicate glass can’t handle that kind of thermal shock, but quartz does. Inside, there’s a halogen gas that basically cleans up after itself. As the tungsten filament wears down, the gas pushes that tungsten right back to the center of the wire. It’s like a self-healing system. It keeps the lamp lasting longer and ensures the heat stays intense. And because the glass is crystal clear, the infrared heat just shoots straight through. Nothing is blocking it. A few things to keep in mind when you’re installing these. They’re designed to be drop-in replacements for most 635mm heater banks, and they play very nicely with PID controllers if you need to keep your temps locked in. Just a heads-up: quartz is tough with heat, but it’s fragile if you hit it. If your shop floor is a bit chaotic or has a lot of vibration, do yourself a favor and throw a reinforced cage or some shielding around them. Also, these things gethot. Really hot. Make sure your cooling fans are up to the task so you don’t melt your sockets. And for heaven’s sake, use high-temp wiring. Standard insulation will just crisp up at the terminals, and nobody wants to deal with a short circuit mid-shift.
