We built this 3-phase electric heater to slip right into industrial machines that need heat fast—and keep it steady, no fuss. Here’s the thing: we run it on 400V three-phase because it spreads the load evenly across all three legs. That keeps the wiring size and contactor stress manageable, while still packing serious wattage into a compact tube.
Power, voltage, and size—why it all clicks
You get 2500W packed into a 300mm tube. That’s high watt-density, exactly what you need when space is tight. And running at 400V brings the amperage down compared to a 230V option at the same power. So you can use smaller wires and cut voltage drop over longer runs. The 300mm length hits a sweet spot: long enough to cover the heating zone, short enough to squeeze into crowded enclosures and get you up to temp quicker.
What’s inside—and why it stays tough
Inside, a halogen capsule runs hot and clean, keeping output steady as the filament cycles. The quartz envelope is coated to shift the spectrum and shield the element from contamination—so it holds up better in gritty, dirty shop air. And the R7s base? Straightforward, proven in the field. It installs fast, stays aligned, and gives you a solid mechanical and electrical connection without fiddling with adapters.
Where it shines—and what to keep in mind
This heater is built for demanding spots like PET blowing and other process heating jobs where you need repeatable heat, quick recovery, and easy replacement. Just remember: with this kind of heat density, you get fast response. But your machine needs proper cooling and airflow around the lamp so nearby components don’t cook.
