The Power Behind Industrial Heat
We built these electric heater tubes for one reason: to get heat exactly where you need it, fast. Here’s the core of it: 400V input, 2500W output. That’s how you get serious heat packed into a small space. The tube is 300mm long, so the heat stays focused right where you want it. And the 10mm diameter? It slips right into standard fixtures—no messing around with new brackets. It throws heat fast, no doubt. But that also means your machine’s cooling has to be up to the task. You need to plan for the extra warmth it puts out.
What They’re Made Of
These are halogen heaters, and they’re built around a tough quartz envelope that can handle extreme heat and sudden temperature swings. Inside, the halogen cycle keeps the filament stable. That’s what fights burnout and keeps the output steady, even through long shifts. And the R7s connector? It’s a straight-up, industrial-grade fit. No adapters needed. Just a solid, low-resistance connection. If you’ve got an R7s socket, this drops right in, which means less downtime during swaps.
How They Actually Perform
You’ll see these tubes shine in focused heating jobs—like PET blowing, pre-heating plastic, or inside process ovens. They combine shortwave infrared with that 400V/2500W punch, so they respond quickly and give you tight control over the temperature. For engineers, that means predictable heat, wiring that stays simple, and fewer maintenance headaches. But here’s the part you can’t ignore: that high heat density needs proper airflow and clearance. Keep it spaced out so you don’t cook the parts nearby.
