On the blow molding floor, the heating tunnel is where you win the cycle—or lose it. When an IR lamp goes down on your Sidel, the line doesn’t just slow down. Preform temperature drifts, stress lines show up on bottles, and scrap starts climbing while you wait for a replacement. We carry Sidel-compatible IR lamps that drop straight back into your heating zones without messing with the tunnel setup. What actually matters on the machine We match the OEM footprint and electrical interface, so the lamp sits in the same holders and connects to the same points on your Sidel blow molder. Pick the emitter that fits the job: short-wave for fast, high-intensity heating; medium-wave when you want a more even temperature profile. The quartz envelope and halogen filament are built for quick thermal response and stable output, so the heating curve stays repeatable shift after shift. Rated voltage and power line up with the machine’s control logic, and the dimensions are held to tolerance so alignment and focus don’t drift. Why it plays in production The payoff shows up on the line. A direct replacement can trim heating energy by 10–15%, thanks to higher efficiency and faster stabilization. In practice, that means faster recovery after changeover and fewer rejects tied to temperature. Expect lamp life of 5,000+ hours under normal duty, which cuts changeouts and keeps maintenance windows predictable. When heating is stable, you can hold cycle speed without overdriving the zone—so throughput stays consistent and you stop chasing hot spots. A few shop-floor reminders Installation is straightforward, but the lamp has to match the specific Sidel model and heating zone. Double-check wattage, base type, and mounting dimensions against the machine spec. Inspect the reflector and clean the holder contacts—bad contact gives you voltage drop and uneven heating. And keep this in mind: more power can deliver faster heat-up, but only if the preform material and line speed are tuned to match.
