The Compact 400V 2500W Halogen Heater: Big Heat, Tiny Package
Ever been wrestling with a machine design where there’s just no room left? Where you need serious heat, but you’re working with a footprint that’s more shoebox than warehouse? This heater was built for exactly that headache. We designed it for engineers who need to pack a lot of power into a seriously small space—think applications like PET blowing, sealing bars, or those compact ovens where every millimeter counts. It’s a shortwave halogen quartz tube, just 300mm long, but it punches way above its weight, delivering 2500W of power from a tube that’s only 10mm across.
Why 400V? It’s all about the space you save.
Here’s the thing: it runs on 400V instead of the usual 230V. Why? Because bumping up the voltage drops the current for the same amount of power. And that lower current is a game-changer for tight spaces. It means you don’t need thick, bulky wiring or oversized terminals. You get thinner cables, smaller connectors, and less voltage drop over the run. In a cramped machine, that’s not just convenient—it’s essential.
Power that fits.
At 2500W packed into a 300mm tube, you’re talking about some serious heat density. That kind of output needs a solid power supply and good thermal management around what you’re heating. But the beauty is in the size. The short length and slim profile slip into those jammed-up areas where a standard coil heater just can’t go.
Built to last, and easy to work with.
The quartz envelope is tough. It handles rapid heating and cooling without blinking, and it runs hot enough to keep the halogen cycle working. That cycle keeps the filament temperature steady, which helps the heater last longer. Plus, there’s a reflective coating on the tube. It pushes more infrared energy forward, so the heat goes where you need it—onto the workpiece, not wasted on the machine frame. And the R7s connector? It’s a simple, two-pin ceramic base that locks in fast and holds the current securely. It’s designed to be a drop-in replacement for many existing setups, so you can swap a unit out on the floor without redesigning the whole thing.
Where it shines.
In PET blowing, this heater gets molds and preforms hot, fast. It keeps cycle times tight. It’s just as reliable in plastic welding, packaging sealing, and those small drying tunnels. You get a heater that starts up instantly, gives you precise control, and takes up almost no room. Just one heads-up: packing this much power into a small tube means the area around it gets hot, fast. So plan your airflow and mounting clearances accordingly.
