We build carbon fiber heat lamps made for one thing: drying paper on the line. And let me be clear—these specs aren’t random. You need a lamp that packs serious heat into a small space, and that only happens when wattage, voltage, and length are matched to your line speed and how wide your paper web runs. Here’s the thing—most of these lamps are high-wattage quartz infrared emitters, often hitting 2500W and running on 400V. That voltage choice isn’t just a number. It keeps the current lower over long runs, so you don’t end up wrestling with oversized cables or losing power to voltage drop across the terminal block. The tube? Usually around 300mm long. That gives you a tight, focused heating zone that fits neatly into compact dryer sections without forcing you to tear the whole oven apart. And because the wattage density is high, the lamp responds fast. When you switch paper grades and need to reset temperatures on the fly, you’re not stuck waiting around. Inside, it’s a carbon filament sealed in a quartz envelope—not a metal coil. Quartz handles rapid heating and cooling without cracking under pressure, and it stays steady at high temps, so you get even heat without hot spots that could scorch coatings. We fill the inside with halogen gas, which keeps the filament clean and stretches the lamp’s working life. Then there’s the R7s base. It’s a practical, no-nonsense choice for industrial dryers. It locks in solid, carries the electrical load, and makes installation straightforward and repeatable. In most cases, it’s a drop-in fit for existing fixtures, so you can retrofit without rewiring the entire machine. On the paper line, you’re after evaporation you can control. Carbon fiber infrared lamps shine here because they put energy directly onto the wet surface, helping you hit your target moisture without overheating the paper. The quick heat-up and clean heat profile help reduce web marking and keep the whole process steady. But there’s a trade-off. All that power density means the lamp needs proper cooling and airflow. If the reflector cavity and ventilation are too small, the lamp—and nearby parts—will run hotter than they should. So you spec the lamp to the dryer, and you spec the dryer to the lamp.
