Technical Deep-Dive: Power and Dimensions
We built these heating tubes for engineers who need serious heat in a seriously tight space. That 400V, 2500W rating? It’s not just a spec on a sheet. It means you get the kind of heat density that keeps fast industrial cycles moving. The dimensions—300mm long, 10mm across—were chosen to slide right into compact chambers and focused zones. So you get a ton of power, but it still fits where you need it to.
Material and Design
The quartz envelope is the real hero here. It handles the shock of rapid on/off cycling without cracking. Inside, the carbon fiber element fires up almost instantly and keeps its resistance stable, day after day. And the R7s connector? It’s a direct, two-ended fit. So when it’s time for a replacement, you can swap it out quickly—no tools needed. This thing is built to take the heat and keep working, shift after shift.
Application and Benefits
These tubes shine wherever you need fast, localized heat—PET blowing, plastic welding, curing, packaging sealing. The combo of quartz and carbon fiber gives you predictable output and temperature control you can count on. Just one thing to keep in mind: that 2500W output needs proper airflow or heat sinking to manage the ambient heat in the machine. For us, the whole point is simple. A drop-in element that wires up clean, runs steady, and keeps your line moving.
