Carbon heat lamps were built for one thing: industrial infrared heating. They’re all about getting intense, focused heat exactly where you need it—fast. And they’re designed to be compact, because in a busy plant, space is at a premium. We make these to run on specific voltages, often 400V, and at seriously high wattages. Because when you’re running an industrial process, you don’t need a gentle warm-up. You need serious heat density, on demand.
Let’s get into the details
Take a typical carbon heat lamp. You’re looking at 2500W, 400V, all packed into a 300mm quartz tube. That 400V setup is smart. It lets you run more power without overloading your wiring and contacts. That means you keep voltage drop and contact heating in check. And the 300mm length? It concentrates the heat into a tight spot, giving you a predictable hot zone that’s way easier to shield and line up. These lamps wake up fast. And once they’re on, they hold steady, even after repeated heating and cooling cycles.
What’s going on under the hood
The quartz tube is the backbone. It can handle extreme temperatures and creates the perfect environment for the carbon filament. We use a halogen fill gas inside to stop the filament from evaporating. This helps the lamp keep its output steady over time and makes it less likely to burn out. The design gives you shortwave infrared, which is just what many plastics and coatings soak up. And the R7s connector? It’s a practical choice. It handles the current, keeps the lamp aligned, and makes swapping out a lamp a simple job.
Where they shine
You’ll see these lamps hard at work in places like PET blowing, plastic thermoforming, and coating curing. Anywhere you need heat, fast, and in a small area. The high wattage, shortwave output, and compact size mean you can build a heating station that’s focused. Less wasted heat. Simpler shielding. Now, there’s a trade-off. That kind of heat density means your machine needs to be smart about cooling and reflector placement. You’ve got to keep the nearby parts from getting too hot.
