Carbon Medium-Wave Infrared Lamps: Power, Design, and Why They Work
We make carbon medium-wave infrared lamps for industrial heating—the kind of heating you need when you want speed and focus, without pushing the target too hard. The whole idea is pretty straightforward: create intense radiation in the medium-wave band, then wrap it in a package that actually fits the machines you run and the maintenance routines you live with.
Power, voltage, and size—built for real-world lines
These lamps are designed around a specific power density. A typical unit hits 2500W and comes in a 300mm length, so you get a tight thermal footprint that fits into cramped spots. We spec them at 400V because higher voltage means lower current for the same power. That lets you use smaller conductors and cut losses along the wiring run. It’s a practical win when you’re running several lamps on one line and want steady performance without oversizing cables.
What’s inside: halogen, quartz, coating, and connectors
The filament is carbon, but the system runs on halogen. The halogen cycle helps keep the quartz envelope cleaner by putting evaporated material back onto the filament, so output stays consistent over time. The quartz tube handles rapid temperature swings and transmits infrared efficiently. Then we add a reflective coating on the outside to push more energy forward—so more heat lands on the part, not on the bracket around it. For termination, we use an R7s connector. It’s a simple, two-ended ceramic design that gives solid contact and makes swapping lamps fast—no fussing, just get it done.
Where it shines—and what to watch for
This setup is commonly used for PET blowing and other plastic forming steps where you need rapid surface heating you can control. Medium-wave output is absorbed well by many polymers, so heating happens faster and you waste less energy heating the machine frame. Just keep in mind: the high heat density means you need proper cooling and clearance. Make sure the reflector and mounting are rated for the temperature, and confirm your controls can handle the inrush current.
