We built this halogen fan heater for the kind of industrial heating that demands pure speed and serious punch. It runs on a 400V supply, packs a 2500W halogen tube, and does it all in a 300mm length. Basically, it’s a powerhouse in a compact footprint.
The power, the voltage, the size
Here’s the thing about running on 400V: it keeps the current lower than a 230V setup. That means less voltage drop and you don’t need heavy-duty wiring for those long runs. And with 2500W, you get serious watt density, so the heater gets your target up to temperature fast. The 300mm tube gives you a predictable heating zone that slips right into tight machine bays.
The guts of it: Halogen, coating, and fit
The halogen element is the kind of steady performer you can rely on. It holds its output over time and doesn’t throw in the towel when the heat cycles on and off. The quartz envelope heats up fast, and the coating helps direct both the light and the heat where you need it. And the R7s end-caps? They’re a direct, drop-in fit for standard holders. So you can wire it up and swap it out on the line without having to redesign the fixture.
Real-world use: PET blowing and heat on demand
In PET blowing, you need heat that responds instantly. You have to soften those preforms quickly without cooking the polymer. This setup gives you that fast response and repeatable temperature control. But there’s a trade-off. That 2500W density means you need solid airflow and proper thermal management around the heater. It keeps nearby components from getting too hot.
