China Electric Heater Supplier: 400V Halogen Heaters with R7s, Built for Industrial Heat
We make industrial electric heaters for engineers who just need heat they can count on. Heat that shows up on time, installs fast, and keeps running without drama. Our focus is on halogen heating lamps—they pack a ton of heat into a small space, and that’s exactly what a lot of machines need.
The power details—why 400V, 2500W, and 300mm make sense
We spec these heaters at 400V because it drops the current for the same power. That means you can use smaller wiring and lose less voltage along the line. The 2500W rating is all about intensity. It warms up quickly and holds process temperatures steady, so you’re not waiting around. And the 300mm tube? It gives you a clean, defined heat zone that fits neatly into many machine channels—without crowding the chamber.
What’s inside: quartz, halogen, coating, and the R7s connection
The envelope is quartz, which handles sudden temperature swings and keeps the heating element safe. The halogen fill helps keep output stable over time by fighting blackening, so the watt density stays consistent. A reflective coating pushes more infrared energy forward, so more heat actually reaches the target. Then there’s the R7s connector. It’s the industry standard for a reason: it’s straightforward. Wire it, line up the pins, and lock it in—done.
Where it shines—and what to watch for
This setup is made for jobs that need tight, focused heat in a small footprint. Plastic heating, adhesive activation, component drying—those are the sweet spots. Here’s the trade-off: 2500W in a short tube means the surface gets seriously hot. So your machine needs to manage airflow and add proper shielding. We supply the heater. You integrate it with cooling and guarding that matches your setup.
