Heavy-Duty Electric Heater: 400V Halogen Tubes for High-Density Industrial Heat
We built these heavy-duty electric heaters to slide right in as direct replacements—tubes for machines that demand serious heat density. They’re made for 400V systems and crank out 2500W, so you get fast, focused heat without dragging your electrical panel to its limit.
Power, Voltage, and Size—Why It Matters
The 400V input isn’t random. It cuts down on current draw, and that means you can use smaller wiring and keep voltage drop in check over distance. The element stays steady where it matters—right at the point of use. And the footprint? 300mm long, 10mm diameter. It’s compact, so you can concentrate heat exactly where you need it, even in tight spots. Plus, with 2500W packed into that space, the heater jumps on target the moment setpoints change. No waiting around.
What’s Inside: Halogen, Quartz, and the R7s Connector
At the heart is a quartz envelope, filled with halogen gas. That halogen cycle keeps the filament stable and fights blackening, so the output stays consistent over time. No dimming. No surprises. Quartz also handles rapid temperature swings and resists thermal shock—perfect for machines that cycle on and off. Then there’s the R7s bi-pin connector. It’s an industrial standard for a reason: wiring is straightforward, the connection holds firm in the holder, and it’s built to handle repeated replacements without getting finicky.
Where It Shines—And What to Keep in Mind
You’ll see these tubes most often in PET blowing, plastic processing, and other industrial heating stations where fast response and steady output are non-negotiable. High watt density plus 400V operation keeps the machine moving—but it also means the surrounding housing and cooling need to be properly matched. Manage the ambient heat, and everything runs the way it should.
