Carbon Fiber Filament Quartz Tube

July 2, 2026

The Heaters We Build for People Who Don’t Have Time for Weak Stuff

We make these tubes for engineers who need a heater that can take a beating and still deliver heat that’s precise and intense. Inside, you’ve got a Carbon fiber filament, tucked into a quartz tube that’s as pure as it gets. It runs on 400V and pumps out 2500W. This is the kind of setup you reach for when space is tight and there’s no wiggle room on thermal performance.

Power, voltage, and size—kept simple

We spec it at 400V and 2500W because that combo squeezes maximum heat into a compact 300mm length. It’s a short-wave halogen design, which means the filament runs hot—really hot—and throws off powerful infrared energy. Matching the wattage and voltage this way gives you a heater that wakes up fast, hitting operating temperature almost immediately. But here’s the thing: that kind of power density brings heat with it. A lot of heat. So your surrounding equipment needs to stay cool. If your machine’s cooling can’t keep up with the temperature rise, you’re asking for trouble—and a shorter life for the parts nearby.

Why the quartz tube isn’t just a shell

The quartz tube is where the magic happens. High-purity quartz handles the shock of rapid on/off cycles and lets infrared energy pass through cleanly and efficiently. Inside, the carbon fiber filament brings serious strength and stable resistance, so it doesn’t sag or snap, even when things get extreme. And the R7s connector? It’s direct, solid, and simple. Gives you a strong mechanical and electrical connection, so swapping in a new tube is straightforward—plug it in and go. The halogen cycle inside keeps the filament clean, which helps the output stay steady over the life of the unit.

Where this shines—and what it feels like to run it

This tube was born for industrial workhorses, like PET blowing, where you need heat fast—right where you need it—without turning the whole machine into a sauna. The 300mm length and focused heat pattern give you a tight thermal footprint. Heat the exact zone, improve control, and stop wasting energy on the parts you don’t need to warm. We built these to be reliable, the kind you install and forget about. They hold steady, go in quickly, and keep going through high-cycle production. If your next project needs serious heat density in a package that’s easy to wire and tough to kill, this is the tube you want.
