Don’t Let Voltage Mismatches Fry Your IR Tubes
Short wave infrared (SWIR) tubes are beasts when it comes to pumping out thermal energy. But here’s the catch: when you’re scaling up production across different sites or countries, the heat isn’t usually the problem. It’s the power coming out of the wall. If you plug a tube meant for 110V into a 480V line, it won’t just stop working. It’ll burn out in a heartbeat. The trick to getting the voltage right We build our tubes for 110V, 480V, and 575V. But this isn’t as simple as slapping a different sticker on the box. If you want a 2000W output but you’re jumping from 110V up to 480V, we have to actually change the physical build of the tungsten filament—adjusting the length and the thickness. The upside? Going with higher voltage (like 480V or 575V) means you pull less current. This is a huge win for your wiring. It means less stress on your system and you can use thinner cables, even in those massive oven arrays. Getting the fit just right We use high-purity quartz glass because these tubes go through some serious thermal shock. It’s a brutal cycle of heating and cooling, and the glass has to hold up. We also make sure the end-caps fit your existing setup perfectly. Whether you’re using a standard R7s or a specialized Sk15, it needs to be a snug fit. Why? Because a loose connection is a recipe for disaster. You’ll get arc points, and that’s the fastest way to kill a tube. A few things to keep in mind High-voltage, high-wattage tubes are incredible for things like PET blowing or curing because they hit hard and fast. But there’s a trade-off. The heat is so intense that your reflectors have to be polished to a mirror finish. If they’re pitted or oxidized, you’re just throwing energy away—and worse, you might actually crack the quartz. It’s worth taking a few minutes every 500 hours to check your reflector alignment. It keeps everything running smooth and saves you from an expensive headache down the road.
