carbon infrared heating tube

June 2, 2026

Introduction

Picture this: you need serious heat, but you’ve got almost no room to work with. That’s exactly why we built our carbon infrared heating tube. This isn’t your run-of-the-mill heater that just gives off a gentle glow. We’re talking raw, focused power. It’s built for industrial jobs where machines run hot and fast, and you need a heat source that can keep up.

The Power Under the Hood

Here’s the thing about getting that much heat out of such a small package. It all comes down to the electrical rating. We run it at 400V, which lets us pack a ton of wattage into a short tube. That means you get a seriously concentrated blast of radiant energy. The payoff? Your machines heat up faster, and your cycle times shrink. We keep the size tight, too—around 300mm long. So it slips right into those cramped spots where you need heat the most. Just keep in mind, that kind of concentrated power means the surrounding area and electrical box have to be ready to handle the extra heat.

What It’s Made Of

We chose a quartz envelope because it can take the heat—and the shock of rapid temperature swings. It stays clear, too, so it keeps that infrared energy flowing strong. Inside, the carbon filament gives you something you can count on. Its resistance stays steady, so the heat output stays predictable, day after day. And for the connection, we went with an R7s connector. It’s a practical, industrial-grade choice. It handles the current, makes a solid connection, and makes swapping out the tube a simple job.

Where It Shines

Think about jobs like PET blowing or other plastic processing. You need heat right where the material hits the mold. That’s where this tube really comes into its own. It delivers heat exactly where you point it, with almost no warm-up delay. You get precise control over the heating, and you don’t have to give up valuable space on your machine. Once it’s wired in, you’ve got a heat source you can trust. It just keeps delivering the same output over time, as long as your cooling and power supply are up to the task.
