Hand Warmer Heater: 400V Halogen R7s Quartz Tube for Industrial Spot Heating
We built this hand warmer heater for one reason: to give you intense, focused heat exactly where you need it. No more warming up the whole room. Just a compact powerhouse that gets straight to the point.
Power, Voltage, and Size—Straight to the Point
This thing is rated at 2500W and runs on 400V. That combo packs a serious punch into a small space, so you get rapid heat, fast. The 300mm tube length keeps all that energy focused in one spot—perfect for tight areas where you need precision, not a blast of ambient warmth. And because it’s 400V, the wiring can be a bit lighter for the same wattage, which helps cut down on losses. Just keep in mind, it does need a control circuit that’s up to the task and proper insulation.
What’s Inside? Halogen, Quartz, and a Smart Base
Inside the tube, halogen gas does the quiet work of keeping the filament stable, which helps extend its life. The quartz envelope handles the rapid heating and cooling cycles without blinking, so the output stays steady. The R7s base makes installation straightforward—just drop it in, and you’ve got a solid, low-resistance connection. The quartz also has a coating that helps manage surface temperature and fend off grime. Still, it needs decent airflow around it to stay cool and do its job.
Where It Shines: Fast, Direct Heat for the Right Jobs
This heater is your go-to for quick, directional heat—ideal for hand warmer assemblies, small drying tunnels, or heating up specific components. The compact size and focused output mean you can design a smaller enclosure and cut down on cycle time. But with that kind of concentrated power comes responsibility. You’ll want to make sure you’ve got proper cooling and thermal management in place, so the surrounding parts don’t get overwhelmed.
