Introduction
We built this carbon fiber heating tube for one reason: to give industrial processes a heat source that reacts immediately and holds tight control. Inside, you’ve got a carbon filament core, a halogen gas fill, and a quartz envelope wrapping it all up. The payoff? A seriously tough heater that can handle extreme heat in tight spots—without the lag that kills your timing.
The Power, in Plain Terms
Here’s the thing: this tube is meant to pack a lot of heat into a small footprint. On a 400V supply, it runs at 2500W. That’s serious wattage, squeezed into a 300mm length. So the heat concentrates where you need it—right on the target zone. That makes a real difference on machines like plastic blow molding and thermoforming lines, because you can hit setpoints fast. And running at this voltage keeps the current lower for the same power, which means you can use smaller conductors and reduce stress on connections.
What’s Inside, and Why It Matters
The carbon filament runs hot—really hot. But the halogen cycle does a smart trick: it helps keep the filament clean by redepositing evaporated material back onto the hot zone. That stabilizes output over time, and it supports longer service intervals. The quartz tube is built for the shock of rapid on/off cycling, and it stays highly transmissive in the infrared. And the R7s connector? It’s a straight-blade, two-pin design that locks in solid—no tools needed. You get a clean, square seat in the reflector every time.
How It Performs on the Floor
On the plant floor, this tube is a drop-in workhorse. PET blowing, plastic heating, and other focused heating jobs—this is where it shines. You get fast ramp-up, predictable temperature behavior, and an install that’s straightforward. But there’s a trade-off you should know: packing 2500W into a short tube means the surrounding hardware has to handle heat. Plan your cooling and shielding so nearby components don’t get cooked.
