Let’s Talk About Twin Tube Infrared Elements
If you’ve ever dealt with “hot spots” that scorch your material or leave you with a curing job that looks splotchy, you know the frustration. Usually, the instinct is to just get a bigger lamp. But that’s not always the answer. That’s where the twin tube comes in. It’s a clever way to get more heating surface without actually taking up more room in your machine. The balance of power Here is the thing about voltage and wattage: it’s all about how the heat spreads. When we set up a dual-tube system, we’re spreading that thermal load. Why does that matter? Because if you cram too much power into a single short tube, the filament gets stressed. It runs too hot, and then—pop—it burns out way sooner than it should. We spend a lot of time tweaking the ohms so the heat feels the same at the very edges as it does in the middle. The hardware side of things We stick with high-purity quartz. It’s the best way to let that shortwave radiation slide right through without getting trapped. Plus, the twin-tube shape gives you a much wider angle of heat. For the wiring, we usually go with R7s or Sk15 connectors. They’re simple, they fit right into most industrial housings, and they don’t wiggle loose when the wires expand from the heat. They just stay put. The catch (and how to fix it) There is a trade-off, though. More surface area means more heat hitting your equipment. If your cooling fans weren’t built for that extra BTU output, your housing is going to get hot. Really hot. Over time, that’ll eat away at your wiring. It’s a common headache, but it’s easy to avoid if you check your ventilation first. We’d rather just come see it Honestly, we aren’t fans of just boxing up a part and shipping it off. We’d much rather come to your shop and look at your thermal profile in person. Seeing how the heat actually hits your specific material is the only way to know for sure if you need a coated tube or a different voltage. It saves you a lot of wasted money and a lot of trial and error.
