Introduction
We built this quartz heating tube with a carbon fiber core for engineers who just want raw, controllable heat—without taking up a ton of space. This lamp is a straight-up workhorse. It’s for jobs that need immediate power, rock-solid temperature stability, and performance you can count on even when conditions get rough. It’s engineered to jump to temperature fast, without the bulk that comes with old-school heating elements.
The Nitty-Gritty
We designed this thing around one idea: serious heat density. These tubes run at 400V, pushing enough current through the carbon fiber to hit 2500W—packed into just 300mm. That gives you a short, intense heat zone, so you can focus energy exactly where you need it. And that 300mm length? It keeps the footprint small enough to slip into tight spots—like on blow molding heads or along conveyor curing stations. The 400V input isn’t a quirk—it’s a choice. It means you need a solid control circuit and proper insulation, sure. But it also buys you the wattage needed for fast, repeatable heating cycles.
What It’s Made Of
The carbon fiber heating element sits inside a quartz envelope because quartz can take high heat without softening, and it handles sudden temperature swings without blinking. On top of that, the quartz tube sends infrared energy efficiently, so you get direct, focused radiant heat right onto the target. We added a surface coating to manage emissivity and protect the element from chemicals and contamination—because durability matters when you’re running day after day. And the R7s connector? Practical, dependable, and easy to wire and replace in the field. It stays secure even when things get hot.
Where It Shines
This setup was born for industrial process heat—where speed and control aren’t optional. In PET blowing, the lamp delivers quick, localized heat that softens the preform exactly when you need it, without turning the whole machine into a sauna. On coating lines, the compact tube slips into tight zones and holds a steady temperature for curing—consistent, shift after shift. The carbon fiber core heats up fast, cutting warm-up time and smoothing out cycle consistency. The quartz envelope keeps everything stable, even when you’re heating up and cooling down over and over. One thing to keep in mind: that much power in such a small space needs thoughtful thermal management. Proper shielding, airflow, or water cooling keeps the surroundings safe and the system reliable. For us, the whole design comes down to this: put dependable heat where you need it, when you need it, and keep it simple to service.
Straight Talk
Let’s be real—this isn’t a plug-and-play bulb. A 400V, 2500W tube packed into a 300mm envelope is purpose-built. It needs a control panel rated for the load, the right fusing, and attention to clearances. Treat it like the engineered component it is, and it will run reliably. Cut corners, and you’re asking for trouble.
