Introduction
Meet the R7s halogen tube. It’s the kind of heating element you want when space is tight but you absolutely can’t afford weak heat. It packs a serious punch into a small frame, throwing out focused infrared heat right where you need it. Perfect for those jobs that demand fast, spot-on heating without messing around.
The Power Behind the Heat
Here’s the thing about these tubes: they’re built to run hot and fast. We’re talking serious power, usually either 2500W or 3000W. That’s how they deliver the intense heat flux that tough industrial processes demand. And that 400V rating? It’s not just a number. It’s there to keep things steady, even when your machines are spread out over a long line. No voltage dips. Just consistent power, exactly when you need it. They come in two main lengths, 300mm or 500mm. Why? Because those sizes match up perfectly with common machine footprints. So you get heat precisely where you want it, and you’re not wasting a single watt.
What It’s Made Of
The heart of the tube is a high-purity quartz envelope. This stuff can handle the extreme heat without breaking a sweat and laughs in the face of sudden temperature swings. Then there’s the halogen gas inside. It’s the secret sauce. It works to keep the tungsten filament clean, which means the tube stays bright and consistent for the long haul. And the R7s double-ended connector? It’s just a solid, no-fuss design. It locks in tight and gives you a reliable connection every time. Seriously, it’s a straight-up replacement that just works.
Where It Shines
These tubes are made for the gritty stuff. Think PET blowing, plastic welding, anything that needs heat that turns on instantly and holds steady. The R7s delivers that—fast ramp-up, precise control. But here’s the catch. All that power packed into such a small space creates a lot of localized heat. So your machine’s cooling system has to be up to the task. That’s not a flaw. It’s just the reality of having a heating solution this focused and intense.
