Wholesale Electric Halogen Heaters: 400V, 2500W, and R7s Connector Engineering
We built these electric heaters for the machines that have no room to spare—the ones where you need serious heat, right now, in a tight spot. Think of this as a quartz halogen tube that’s purpose-built: 400V, 2500W, delivering predictable, high-intensity heat in a package that stays out of the way.
Power, Voltage, and Size—Why It Matters
Here’s the thing about the 400V, 2500W rating: it gets hot fast, but it pulls less current than the lower-voltage, higher-amp options. That means you can use lighter wiring, and it keeps the load on your control panel from feeling like it’s about to throw its back out. And at 300mm long, the power is focused into a small zone. So you can heat the exact spot you need—without turning the whole machine into a sauna.
What’s Inside: Halogen, Coating, and the R7s Base
The quartz envelope handles serious heat and takes thermal shock in stride. Inside, the halogen cycle keeps the filament stable by sending tungsten back where it belongs—instead of letting it blacken the tube—so the output stays steady over the life of the lamp. A reflective coating pushes the energy forward, so more of the heat actually lands on the target. And the R7s connector? It’s a simple two-pin ceramic base that locks in place and makes wiring quick. If your fixture already takes R7s, this is a straight drop-in replacement.
Where It Shines: Tough Heat, Precise Control
These heaters are made for the jobs that demand intense, controllable heat: PET blowing, plastic welding, sealing bars, and small ovens. The watt density is high, so you get quick response—but that also means you need to plan cooling and mounting with care. Expect a hot surface and a tight, focused hot zone. So plan your guarding and thermal isolation accordingly.
