Sidel SBO 24 Series 2 Infrared Radiator: A Straight Swap for Krones Lines
We built the Sidel SBO 24 Series 2 infrared radiator for one simple reason: to give you a no-drama replacement when Krones Contiform maintenance costs start climbing. It’s designed as a direct, drop-in fit—same thermal performance, same mechanical footprint—so you can keep your PET blowing running without overthinking it. Just swap it in and get back to work.
Power, voltage, and the real-world details
This unit runs on 400V, and that matters when you need fast ramp-up for short heating cycles in PET blowing. Higher voltage at this wattage means lower current, which eases the stress on conductors and terminals. Less heat buildup in the wiring too. And the 300mm tube length? That’s intentional. It concentrates the heat into a tight zone, so you get high heat density without taking up more space than necessary.
What’s inside—and why it stays reliable
Inside, you’ve got a halogen element delivering stable shortwave infrared output. The quartz tube handles rapid heating and cooling cycles without cracking under the pressure. We also applied a coating that pushes more energy where it needs to go and reduces surface losses. So you get consistent heating with less wasted energy. And the R7s connector? Practical choice. It locks in fast, holds steady under vibration, and makes replacement quick—no rewiring the whole heater block.
Fit for Krones Contiform, with real-world expectations
This configuration is spec’d to drop straight into Krones Contiform systems, so a burnt-out radiator doesn’t turn into a re-engineering project. You get predictable heating, faster changeovers, and fewer surprise stops. Now, here’s the part to keep in mind: the 400V, 2500W density works best when the machine’s cooling and electrical interface are in good shape. Keep ambient temperature and contact resistance under control, and you’ll protect tube life. Let those slide, and the tube won’t last as long.
