Introduction
We built this commercial radiant heater to do one thing really well: deliver raw, direct heat for serious industrial jobs. It’s a 400V, 2500W halogen quartz tube—about 300mm long—and it plugs straight in using an R7s connector. The whole point? Packing a ton of heat into a small space, so you can get the temperature up fast, right where you need it.
Technical Deep-Dive
Here’s the thing about running on 400V: it keeps the current lower than a 230V setup would for the same power. That means less voltage drop over the line and thinner copper inside the machine. And with 2500W packed into just 300mm, the power density is high. So it heats up almost instantly. Perfect for jobs that cycle on and off—you’re heating the part, not the whole room.
Material & Design
Inside, the halogen gas does its job—keeping the filament stable and slowing down that blackening effect on the quartz. That means you get consistent output over the life of the lamp. The quartz itself handles wild temperature swings without cracking, and it stays crystal clear for strong infrared transmission. And the R7s base? It locks in solid and lines up perfectly. No fiddling with fragile wires when you need to swap it out.
Application & Benefits
This is the kind of heater you lean on when you need heat that hits deep and repeatable, but don’t have room to spare. Think plastic forming, adhesive curing, drying parts—anything that needs focused, reliable heat. Just keep in mind: with this much power density, the surrounding enclosure and cooling setup need to be ready to handle the energy. But when it’s all dialed in, you get predictable output, clean geometry, and a straight-forward replacement that fits right in—no drama.
