The 3kW Halogen IR Tube, Explained Like You’re Actually Going to Use It
Let’s talk about the 3kW Halogen IR Tube. We built this thing to be a serious workhorse for industrial heating. It’s all about packing a ton of power into a small space. That 3kW rating? It means you get a really intense, concentrated blast of heat, right where you need it. To make that happen, it runs on high voltage—typically 400V. That’s what gets the filament fired up and delivers that almost instant heat. And the size? It’s compact. Usually, you’re looking at a tube that’s around 300mm long. This means your heating zone is tight and focused, which is perfect for fitting into machines where space is at a premium.
What’s It Made Of?
The heart of it is a high-purity quartz envelope. This stuff is tough. It can handle the shock of heating up and cooling down quickly, and it does a great job of letting the infrared energy pass right through. Inside, the halogen cycle is doing the heavy lifting. It keeps the tungsten filament clean, which stops the tube from getting that blackened look. The payoff? A long life and a steady, reliable output that just keeps going for thousands of hours. Then there’s the R7s connector. This is the standard, two-point contact that makes installation straightforward. It’s designed to handle the high current without getting hot itself. So you can just pop it in and know it’s a solid, drop-in replacement for what you already have.
Where It Shines (And What to Watch For)
This tube is your go-to for jobs that need fast, focused heat. Think plastic welding, PET blowing, or curing. The shortwave IR output gets right into the material, so you get results immediately. But here’s the thing with that kind of power density: it generates a lot of heat. So, you absolutely need to make sure the machine it’s in has proper cooling. Without good heat sinking, things will get too hot—both the components around the lamp and the lamp itself. And that will cut its life short. Treat the heat management right, and you’re golden.
