carbon fiber filament quartz IR heat tube

May 9, 2026

Introduction

Ever need heat that just shows up and gets to work? Right now. No fuss. That’s what we build these carbon fiber filament quartz IR heat tubes for. They’re made for industrial jobs where space is tight and you can’t wait around for things to warm up. These are shortwave infrared lamps, and they deliver concentrated radiant heat straight onto the target—without turning the whole room into an oven.

The Nitty-Gritty

Here’s the thing: these tubes run on high-voltage supplies—often 400V. Why? Because stepping the voltage up lets you pack a lot of wattage into a small footprint. A unit around 300mm long can still hit 2500W. That kind of power density means you get fast ramp-up and tight control over the heat. But—and this is important—it also means your control gear and cooling need to be chosen carefully. Shorter tubes concentrate the heat. Longer ones spread it out for bigger zones.

What’s Inside (and Why It Matters)

The quartz envelope is built to handle rapid on/off cycling without cracking under thermal shock. It also transmits shortwave IR cleanly, so the energy goes where you need it. Inside, the carbon filament is halogen-stabilized. That helps it stay consistent at high temperatures and keeps output from dropping off over time. The quartz coating is tuned to shape the IR spectrum and keep the surface temperature high. And for installation, the R7s base is a tough, line-voltage connector that just drops right into standard holders. No complicated setup.

Where It Shines (and What You Feel)

These tubes are a strong fit for PET blowing, thermoforming, drying coatings, and curing adhesives. Because the heat is radiant, it hits the part directly. You feel it in faster cycle times and less wasted energy heating up machine frames. The footprint is compact, so it fits into tight machine bays. And the R7s connection makes wiring straightforward. Just keep in mind: you’re getting serious heat density. Plan your cooling and electrical protection accordingly. This isn’t a low-temp heater—it’s a real workhorse built for demanding work.
