China Electric Heater Supplier: The 400V 2500W Halogen Quartz Tube, Spec’d Right
We don’t build heaters on hype. We build them on hard specs that actually matter. At the heart of our industrial heaters is a 400V, 2500W halogen quartz tube. It’s 300mm long and engineered to pack serious heat into tight spaces.
Power, Voltage, and Size—Why It Matters
Go with the 400V input and you’re looking at lower current on the line. That means less voltage drop, so you can run longer cables without having to oversize the copper. And that 2500W rating on a 300mm tube? It gives you a high watt density. The payoff is fast heat-up and steady temperature control, especially in those compact zones. Just make sure your supply and controls are up to the task—this is a serious load.
Halogen, Quartz, and the R7s Connector
The halogen fill does a smart thing: it keeps the filament stable and stretches the life of the tube by managing tungsten migration inside the quartz envelope. The quartz body, meanwhile, takes thermal shock in stride. It keeps output consistent, even with repeated on/off cycling. Then there’s the R7s connector. It’s a straight-in, two-pin design that wires up quickly and locks into place. Translation: it’s a drop-in replacement for existing fixtures.
Where It Shines—And the Trade-Off
This setup is built for industrial work like PET blowing and plastic preform heating—any station where fast response and a small footprint are key. Here’s the trade-off, though. The lamp delivers intense, localized heat. So your machine needs solid cooling and thermal management to keep ambient temperatures in check.
