Clothes Dryer Heater: 400V Halogen Infrared Tubes with R7s Connectors
We built these dryer heaters as 400V halogen infrared tubes because industrial drying isn’t about gently warming the air. It’s about hitting moisture on fabric—fast—with direct, targeted heat. The result? Drying that feels immediate, not like you’re waiting around.
Power, Voltage, and Geometry—Why It Matters
Here’s the thing about 400V: at the same wattage, it keeps the current lower than 230V. That matters because lower current means you can use smaller wiring, smaller contactors, and you don’t have to fight voltage drop across long runs. And the size? A 300mm length with a tight diameter concentrates the heat into a small footprint. So you can pack serious power into a compact dryer drum—without having to rethink the whole chamber.
What’s Inside: Halogen, Coating, and R7s
Inside the quartz tube, halogen gas helps keep the filament temperature stable, so the output stays steady over time. No mood swings. No surprises. Then there’s the reflective coating. It pushes more infrared energy forward, so you get more usable heat per inch of tube. And the R7s connector? It’s a straight, bi-pin design that snaps in quickly and stays put, even when the ends run hot. No loosening. No wiggle. Just a solid connection you can trust.
Real-World Use: Fast Drying, Tough Conditions
In a clothes dryer, this setup dries loads faster by delivering infrared energy straight into the wet fibers. It feels direct—like the heat knows exactly where to go. The quartz envelope handles thermal shock without blinking, and the R7s connection makes replacement a simple drop-in job. No wrestling. No headaches. Just one note: because the heat density is high, you need proper airflow and clearance. Plan your cooling and spacing from the start, and you’re set.
