Electric Blow Heater: 400V Halogen Lamps That Keep PET Blowing Moving
Picture this: a heating solution that’s small, focused, and gets straight to work. That’s what you get with an electric blow heater built around a halogen lamp. It’s all about direct, targeted heat for PET blowing and other plastic forming lines. The whole point is hitting that preform with the right heat, right where you need it. No guesswork. No scorched material. Just consistent, repeatable results that keep your line running smoothly.
The Specs, Straight Talk
We built these heaters to run on 400V. Why does that matter? It keeps the current draw on your line lower, which means you don’t have to over-spec your wiring and contactors. Less hassle, more peace of mind. And the 2500W rating? That’s the muscle behind fast preform heating. It delivers the kind of heat density that keeps up with your pace. The size is just as practical. At 300mm long and 12mm in diameter, it slips right into standard reflector setups. No redesigning your machine footprint—just a predictable heating zone you can count on.
Built to Last, Built to Work
Here’s the thing about the halogen element: it stays steady. Over time, the output stays stable, so you don’t get surprises mid-run. And the quartz envelope can handle the shock of rapid on/off cycles without cracking under pressure. Plus, there’s a reflective coating on the back of the tube. It pushes more energy forward, so more of the heat actually reaches the preform surface. Efficiency you can feel. Then there’s the R7s connector—two pins, straight-forward, and easy to wire up. It locks into the holder with a solid, secure fit. That solid connection helps prevent hot spots at the ends, which is exactly the kind of detail that keeps things running without a hitch.
What It Feels Like on the Line
When you’re blowing PET, timing is everything. You need heat, and you need it fast—every single cycle. This setup gives you high heat density in a compact footprint, so you can push your speed without tearing apart the oven section. But there’s a trade-off. That 2500W density does kick up ambient heat around the lamp. So your machine’s cooling and airflow need to be up to the task. Match the setup to your system, and you’re golden.
