Introduction
Let’s talk about the glass tempering preheating lamp. We built this thing for one reason: to nail the instant tempering phase in glassware production. It’s a focused solution, plain and simple. It uses shortwave infrared halogen technology to get the job done. This means you get rapid, targeted heat right where you need it. The whole point is to handle the thermal shock that makes the preheating stage so tricky.
Technical Deep-Dive
Here’s the heart of it. The lamp is a powerhouse, packing a 2500W punch on a 400V supply. That’s a serious industrial setup, designed to work with heavy-duty control systems, not your home wiring. This power-to-voltage ratio is what gives you the wattage density needed to heat glass surfaces fast. And fast is the name of the game. You get that intense heat without overloading the line. The size is no accident, either. We settled on a 300mm tube length. It’s a calculated compromise that gives you a focused heating zone that fits perfectly into standard machine housings. No wasted space. Just the right fit.
Material & Design
Inside the quartz envelope, the halogen filament cycle keeps the output stable over the lamp’s entire life. No fading. No flickering. Just consistent performance. The shortwave infrared spectrum is the secret sauce. It dives right into the glass surface, which cuts down the time the material spends in that critical thermal transition zone. Less time in the danger zone means fewer headaches. And don’t overlook the R7s connector. It’s not just a detail; it’s a double-ended, high-temperature ceramic base. It locks the lamp in place and handles the high current without melting. It’s a true drop-in fit for most tempering machine fixtures.
Application & Benefits
Out on the shop floor, this setup means you can adjust power on a dime. You can ramp up and down in seconds to keep pace with the line speed. That responsiveness prevents thermal shock. The glass just doesn’t crack before it even makes it to the quench station. But here’s the thing about that kind of power: it comes with heat density. A 2500W tube puts out a lot of energy, so your machine’s cooling system has to be up to the task. You’ll feel the ambient temperature rise near the lamp. So, size your cooling properly. If you do, the lamp will take the beating, cycle after cycle, and keep delivering that consistent output.
