Carbon Fiber Heating Tube

Technical Deep-Dive: Power, Voltage, and Dimensions

Here’s the thing about these tubes: they pack a serious punch in a small package. We’re talking 400V, 2500W of raw heat, all coming from a 300mm active length. That’s a lot of heat density, which means you get up to speed fast—no need for a giant, bulky enclosure. And the 10mm diameter? Keeps the profile slim. It slips right into those tight clamshell heaters and focused spots where space is at a premium. We chose this voltage and power combo specifically to push current through the carbon fiber element quickly, so machines like PET blow molders hit their target temps without the wait.

Material & Design: Halogen, Quartz, and Connectors

Inside the quartz envelope, the halogen cycle does the heavy lifting. It keeps the carbon fiber element stable, even when things get scorching, and fights off blackening over time. The quartz body itself? It handles the thermal shock like a champ. Turn it on and off repeatedly, and it still delivers consistent output. Then there’s the R7s connector—a simple, straight-through, two-pin design. It wires up easily in line-up fixtures and gives you solid, reliable contact, even with high current. Need a different mounting footprint? We’ve got you. The SK15 option gives you a more secure mechanical lock, perfect for those high-vibration machine bays where you can’t afford a loose fit.

Application & Benefits: Tough Plant Duty

These tubes were born for the industrial grind—PET blowing, thermoforming, packaging line heating. That high heat density lets you shrink the heater footprint, which makes retrofits simpler and servicing the machine way less of a headache. But let’s be real: that 2500W output comes with a trade-off. You need proper cooling and wiring to match. If your machine is specced for it, you get fast response, steady temperature control, and a tube that can handle the relentless heat cycles of a running plant.
