Let’s Talk Carbon Fiber Infrared Heating

Ever tried to heat something deeply without accidentally torching the surface? It’s a tricky balance. That’s exactly why we build our carbon fiber far infrared (FIR) tubes. Instead of using those old-school tungsten filaments you find in halogen lamps, we use a carbon fiber element tucked inside a quartz sleeve. It’s a different approach that just works better for certain jobs.

How the heat actually works

Here is the deal: when current hits that carbon fiber, it puts out radiation in the 2.0 to 4.0 micron range. Now, that sounds like textbook talk, but all it really means is that the heat “fits” perfectly with organic materials and polymers. It sinks in deep. You can pick the voltage and wattage that fits your setup. But a word of caution—don’t just crank the wattage to the max. If you push too much power into a short tube, you’ll get hotspots. And hotspots lead to burnouts. Simple as that.
