We built this 400V, 2500W halogen convector heater for the places that need serious, controllable heat—without taking up a ton of room. It’s the kind of unit that warms up fast and holds steady, so you can count on it when the machine or the process is counting on you. Here’s the power story in plain terms. Running 2500W off a 400V supply gives you a lot of heat in a small space. That means you can focus the heat right where you need it without having to go bigger than necessary. The tube is just 300mm long, so it slips into tight spots without a fight. And because it’s 400V, the current draw is lower than you’d get with lower-voltage options, which makes cable sizing and contactor loads easier to manage. Just one thing to keep in mind: that concentrated heat is powerful, so plan your cooling and clearances. Give the surrounding equipment a little breathing room, and everything runs calmer. Inside, we use a halogen element in a quartz tube. It responds quickly and keeps output consistent over time, which is the kind of steady you want when you’re in the middle of a job. The reflective coating on the tube pushes infrared energy forward, so more of the heat lands on the target instead of spilling to the sides. And the R7s connector? It’s a two-pin ceramic setup that’s been proven in the field. Wiring is straightforward, and it stays solid even when you’re swapping things out again and again. If you’re doing a replacement, it’s a simple, drop-in fit on standard fixtures. Where does this heater shine? Think convection-assisted drying, pre-heating parts, and plastics processing—anywhere you need temperature to snap back fast. The shortwave infrared output, compact size, and 400V operation come together to give you quick heat-up, predictable control, and easier integration into existing panels and frames. It’s strong, it’s focused, and it gets the job done. Just remember to size your thermal management to match the punch it packs.
