When you’re working with glassware, annealing isn’t just a step—it’s a delicate dance. One wrong move, and you’re dealing with thermal shock. That’s why we built our infrared heating lamps for the one moment that matters most: the instant tempering phase. Here’s the thing about that phase—it demands speed. Real speed. The kind where you need to adjust power in a heartbeat. Power, Voltage, and Geometry—Keeping It Tight We designed these heaters to pack a serious punch. We’re talking 400V at 2500W, delivering concentrated energy right where you need it. The tube is just 300mm long, so the heat zone stays tight, fitting neatly into your annealing line. This kind of power density means the lamp hits the setpoint almost instantly. It’s fast. Really fast. But that speed comes with a catch—your machine’s cooling system needs to be up to the task. No shortcuts. Without solid airflow, the surrounding components will start to overheat. Inside the Heat: Halogen, Quartz, and a Smart Connector Inside, you’ve got a halogen element tucked inside a quartz tube. Quartz is tough—it handles the constant shock of rapid heating and cooling without cracking. The halogen gas keeps the filament output steady, even during those long production runs. Plus, the shortwave output targets the glass directly, so you’re not wasting energy heating the whole room. And the connector? We went with an R7s. It’s practical. It gives you a secure, direct mount that holds steady under the current, and it makes replacements a breeze when maintenance rolls around. On the Line: Heat That Responds Out on the production floor, you need heat that moves as fast as you do. These lamps give you instant power modulation, so your controller can match the thermal profile without overshooting. The payoff? Consistent annealing with no micro-cracks from thermal shock. The compact size also makes integration easy—less rework, less downtime. One thing to keep in mind: that high power density is exactly what gives you the speed you need, but it also means you’ve got to plan your cooling carefully. Get the airflow right from the start, and you’re golden.
