Carbon Fiber Halogen Heating Tubes: Precision Heat, Packed Tight

We built these carbon fiber heating tubes for engineers who need serious heat—predictable, high-density heat—in a small footprint. Think halogen-based quartz tubes made for real industrial machines, where fast warm-up, steady temperature, and connections you can actually trust matter.

Power, Voltage, Size: The Practical Details

These tubes run on 400V and pump out 2500W across a 300mm length. That’s intentional. High voltage keeps current lower, so you lose less in the lines and can pack more power into a short space. The 300mm length gives you a clean heat zone that fits standard machine channels—no need to redesign the whole heating block. And 2500W? It hits setpoints fast. But it also means you have to treat thermal management like a real part of the job. If your machine runs in a tight spot, plan cooling and airflow early so nearby parts don’t bake.

Built to Take the Heat: Halogen, Quartz, and a Reliable Connection

Inside each tube, the carbon fiber element runs hot—and the halogen cycle helps keep it stable by cutting down on deposits on the quartz. The quartz envelope handles rapid on/off cycles better than a lot of other glass options, so performance stays consistent shift after shift. We use an R7s connector because it’s a proven industrial standard for this form factor. It gives you a solid, two-terminal connection that’s quick to wire and holds up when things vibrate. The design is drop-in ready, so swapping a tube doesn’t mean reworking the socket.

Where This Tube Shines

This setup is made for applications that need fast, controllable heat in a tight space—PET blowing, plastic pre-heating, packaging sealing stations. The high watt density cuts cycle time, and the element stays steady once you hit your setpoint, so temperature drift isn’t a constant battle. The trade-off is honest: you get aggressive heating performance, but you have to treat it like a high-power thermal system. Spec the right cooling, mount it with proper clearance, and wire it to the rated voltage. Do that, and you’ve got a heat source on the shop floor that’s dependable—and easy to replace when it’s time.
