Clear Medium Wave Carbon Fiber Heating Tube: Power, Design, and Real-World Use
We built the Clear Medium Wave Carbon Fiber Heating Tube for the kind of industrial heating jobs where speed and precision matter. You know the ones—plastic forming, coating curing, component drying. It’s a quartz-based infrared emitter that brings the heat, fast, and keeps temperature control tight. And the best part? It packs serious power into a small footprint, so you can upgrade older equipment without tearing the whole machine apart.
What makes it tick
Here’s the thing about the medium wave output: it lands right in the sweet spot for how many materials absorb heat. The tube heats up quickly—and just as quickly cools down when you cut the power. That snappy response helps you hold your setpoint without overshooting and wasting energy. Most setups run at 400V, and the power rating scales with tube length. A 300mm tube, for example, can hit around 2500W. That’s a lot of watt density in a short package. This isn’t a gentle element. It’s built for concentrated heating zones where space is tight and cycle times are short. The high voltage isn’t arbitrary. It keeps current lower for a given power, which means you can use smaller conductors and cut down on connection losses. Just remember: you still need to size your wiring, contactors, and insulation properly for 400V. And of course, proper guarding and terminal protection matter—safety first, always.
Built to last, built to perform
Inside the clear quartz envelope, you’ve got a carbon fiber heating element. Why carbon fiber? It gives us stable resistance and predictable behavior as temperatures shift. It also handles thermal shock far better than many wound wire elements, which means fewer surprises on the floor. The envelope is clear on purpose. We want the infrared energy to get straight to the target, with nothing blocking the path. Clear quartz also helps with fast heat-up and cool-down, which is a big deal when you’re running short cycles and can’t afford to wait around. For the base, we use the R7s connector—an industrial workhorse. It gives you a rigid, two-point contact that stays solid even in high heat and vibration. Wire it once, and it stays put. If your machine needs something different, we can spec SK15 or other connectors, but R7s is the standard for drop-in replacement in many heating fixtures.
Where it shines—and what to keep in mind
Use this tube wherever you need fast, localized heat: PET blowing preforms, thermoforming sheets, shrink tunnels, and oven zones. The medium wave profile heats plastics and coatings evenly, so you get the punch you need without scorching the surface. That means production keeps moving, and quality stays consistent. Because it’s compact, fitting it into existing machines is straightforward. The quick response also cuts idle time when you change setpoints. But there is a trade-off: high watt density means your reflector geometry, airflow, and cooling need to match the heat load. Get the cooling and mounting right, and this tube will take the beating day after day without burning out early.
