The 640mm 2600W Carbon Fiber Heat Tube: Power You Can Count On

We built this 640mm carbon fiber heat tube for the kind of work that doesn’t forgive weak links. If your equipment needs heat that’s focused, steady, and tough as nails, this is it. For engineers who want a heating element that can take a real beating and still show up for work the next day.

Power, Voltage, and Size—Straight to the Point

Here’s the heart of it: 2600W packed into a 640mm active length. That gives you serious power density. The payoff? Fast heat-up and stable temperature control, especially when space is tight. The resistance stays predictable, and the performance stays repeatable across the whole operating range. Just keep one thing in mind: this tube is designed for industrial voltage systems, and that kind of wattage density needs the right electrical setup. Plan for proper cooling and thermal management. When you pack this much heat into a small footprint, the area around it will get warm. Plan accordingly.

What It’s Made Of—and Why It Matters

The carbon fiber element is the secret sauce. It responds quickly and spreads heat evenly. And compared to traditional wire elements, it handles thermal shock better—so it lasts longer when you’re cycling on and off. The quartz envelope keeps the element stable and shields it from contamination. Then you get R7s or SK15 end-caps for solid, industrial-grade connections. Wiring is straightforward, and those connections stay tight. No fuss. No wiggle. Just dependable contact.

Where It Shines—Real-World Applications

This tube is a natural fit for PET blowing, plastic welding, and packaging sealing. The fast response helps cut cycle times, and the compact size makes it a clean, simple swap-in. You get consistent output even during long runs. But there’s a trade-off worth remembering: high power density means your machine’s cooling has to be up to the task. Spec the heat tube, then make sure your cooling matches it. Do that, and you’re set.
