We build carbon quartz tube heaters for engineers who need serious infrared power—without taking up a ton of space. These aren’t your everyday bulbs. They’re purpose-built, high-temperature emitters, designed to snap to attention and deliver steady heat when your equipment is under pressure.
What makes them tick
These tubes run on high-voltage supplies—think up to 400V—and pack around 2500W of power into a 300mm length. That gives you a clean, defined heat zone that fits neatly into tight machine cavities. Turn them on, and they jump to life. The heat comes fast. No waiting around. Perfect for cycles where you can’t afford to twiddle your thumbs while a bulky heater slowly warms up.
The guts behind the heat
The quartz envelope takes the abuse of rapid on/off cycling and stays steady even when the filament runs hot. No oxidation worries. Halogen gas inside keeps the filament stable, so the output stays consistent over the life of the tube. A smart coating shapes the energy, pushing it into the infrared band. That means plastics and other materials absorb the heat efficiently. And the R7s base? It’s a straightforward, secure connection that installs quickly in fixtures built for this standard footprint.
Where they shine
These tubes are made for focused, line-of-sight heating. PET blowing. Thermoforming. Plastic welding. You get predictable heat input and repeatable results, thanks to the high wattage, compact length, and IR-optimized coating. One heads-up: the heat density is intense. Make sure your fixture has enough cooling and proper clearance, so nearby components don’t get cooked.
