On a blow molding line, the heating tunnel is where the whole run either makes sense or falls apart. If the infrared radiator is weak, you start seeing temperature drift across the preform wall. Stretch ratios get sloppy, and then you’re chasing rejects—hazing, stress cracking, and bottles that are off on weight. The Sidel SBO 24 infrared radiator is built to replace that guesswork with heat you can count on, shift after shift. Here’s what matters under the hood. It’s a short-wave infrared emitter, designed to heat PET preforms fast, with the heat concentrated at the surface where you need it. The quartz envelope gives you high radiant density and snappy response, so the machine can hit the required temperature rise without overshooting. The whole design is matched 1:1 to the SBO 24 heating zone—voltage, wattage, and lamp geometry all line up with the OEM thermal profile. That means a controlled temperature curve across the preform and a stable thermal field in the tunnel, from startup all the way through long runs. In the SBO 24, preform heating is a balancing act. You need enough penetration to soften the material evenly, but not so much that you scorch the surface. This radiator hits that balance because it matches the original machine’s heat-zone layout, emitter spacing, and reflector geometry. You keep the same cycle capability, cut heating-related scrap, and stop paying for the hidden cost of lamp-to-lamp variance. Energy use stays predictable because the output is matched to the zone, not estimated. Installation is straightforward, but the details are where you win or lose. Match the exact lamp length, wattage, and R7s connector orientation to your SBO 24 revision, and check the reflectors. Pitting or oxidation will throw off the heat pattern even with a brand-new lamp. The emitter will reach stable output quickly, so set your startup procedure around that. Keep the emitter clean and aligned—misalignment skews the heat map and shows up fast as uneven bottle thickness.
