SK15 Quartz Halogen Heating Tube: Big Heat, Small Package

Picture this: you’ve got a tight spot on your machine, and you need heat—fast. No room for a bulky heater. No time to wait around. That’s exactly where the SK15 Quartz Halogen Heating Tube shines. It’s built for industrial work where space is precious and speed is everything.

The power behind the punch

Let’s get down to the numbers, but keep it real. These tubes run at 400V and crank out 2500W of power from a tube that’s just 300mm long. That’s a lot of heat packed into a small footprint. The payoff? You get rapid heat-up and immediate response the moment you need it. And because it’s high voltage, the current stays manageable. That means you can run several tubes without needing to beef up your wiring and contactors.

What makes it tick

The tube is wrapped in quartz, not regular glass. That matters when you’re heating up and cooling down quickly. Quartz handles the shock and the cycling better, so you’re not stressing about it cracking under pressure. Inside, the halogen cycle does a clever trick: it redeposits material back onto the filament as it evaporates. This keeps the output steady over the tube’s life. No fade. No surprises. The tube puts out shortwave infrared, which many industrial materials soak up efficiently. So you’re not wasting energy—you’re delivering heat right where it counts. A reflective coating on the back pushes the energy forward, so more of the power goes into the work and less spills onto the mounting side. And the SK15 and R7s connectors? They give you a solid, two-point contact that’s easy to wire and holds up when things get shaky.

Where it shines in the real world

These tubes are a natural fit in plastics processing, especially PET blowing, where you need fast, focused heat. The compact size means you can slip them into tight corners without redesigning the whole machine. And the quick thermal response keeps pace with high-speed cycles. One thing to keep in mind: this kind of concentrated heat is powerful. You’ll want proper cooling and thermal management in place to keep surrounding components and the surrounding air at a safe temperature. It’s heat on demand, in a small footprint, ready to work as hard as you do.
