Industrial Foot Warmer Heater: 400V 2500W Halogen R7s Quartz Tube
We built this foot warmer for one reason: to turn a freezing shop floor into a bearable place to stand. It’s compact, but it throws serious heat. The heart of it is a 300mm halogen infrared tube, running at 400V and 2500W. That power level isn’t random. It’s chosen so you can wire it straight into the 400V three-phase lines most industrial plants already have. No extra transformer. No messing around. Just plug it in and get to work.
Power, Voltage, and Size—Kept Real
2500W packed into a 300mm tube means a ton of heat in a small space. It warms up fast, and it focuses the heat right where you need it—at your feet. The 400V rating also keeps the current draw reasonable for plant power, but that does mean your fixture and wiring need to be rated for that voltage. And the 300mm length? It’s made to drop right into standard foot warmer housings. So if you’re replacing an old unit, it’s a clean swap.
What’s Inside: Halogen, Coated Quartz, and the R7s Connection
The tube itself is quartz, filled with halogen gas. Why does that matter? Halogen helps keep the filament stable when things get scorching hot, so the heat output stays consistent over the life of the tube. Quartz handles the thermal shock without cracking, and the coating helps control the heat spectrum while shielding the filament. Then there’s the R7s connector—double-ended, linear, and designed to lock the tube in securely. It carries the full load without needing extra base hardware. It’s simple, solid, and meant to stay put.
Built for the Shop Floor—And the Realities of It
Shop floors are rough. You’ve got vibration. Dust. Moisture. This heater is built to take it. It delivers high heat density right where someone is standing, so the immediate area warms up quickly. But here’s the part that matters: it needs proper airflow and housing design. If the cooling isn’t matched to the heat output, the surrounding components can run too hot. We sized this for performance, and the trade-off is straightforward—give it the cooling it needs, and it will keep running, shift after shift.
