Krones Contiform S Heating Tube: Keeping Pace with High-Speed SACMI Lines
Here’s the thing about running a high-speed SACMI line: the whole line is only as fast as its slowest part. And honestly, the heater can’t be that part. That’s exactly why we built the Krones Contiform S heating tube. It’s a shortwave halogen tube, engineered to be a direct fit for your SACMI rotary blow-molding machine. It gets hot, fast. So you’re not left waiting around for the heat to catch up. You just keep moving.
The Power Behind the Speed
Let’s get into what makes it tick. It’s all about getting the power where you need it, when you need it. This unit runs on 400V, which means the current ramps up almost instantly. You get 2500W of power—just enough to shoot the temperature up quickly and then hold it steady, cycle after cycle. And the 300mm length? That’s not a random number. It’s sized to match the heating zone perfectly. You get focused heat right where the preform needs it, with no wasted energy and no extra heat spilling over into the machine.
Built to Stay Tough
Inside, you’ve got a shortwave halogen element. It gives you that fast, repeatable heat with tight control. The quartz envelope is coated, which helps manage the heat and protects the whole thing from stress. The result is a steady, consistent output, even during those long, grueling runs. Then there’s the R7s connector. It’s a no-nonsense industrial connection that locks in solid. It reduces resistance and holds tight, even when the machine is vibrating and shaking. You wire it up, clamp it down, and it stays put. No fuss.
The Real-World Difference on Your SACMI Line
On a SACMI rotary blow-molding system, the real bottleneck is often start-up time, not the machine’s actual speed. This tube is designed to be a drop-in replacement that solves that. It starts fast. It stays in sync. You get a quick heat-up, a stable temperature even during high-rate cycles, and maintenance is easier thanks to that straightforward R7s connection. Just one thing to keep in mind: with that kind of power density, the tube needs proper cooling and clean airflow around it. Keep the environment within spec, and it’ll perform without a hitch.
