Stop the Heat Drift in Your Sidel SBO Series 2
If you’ve ever dealt with uneven wall thickness or bottles that just look… off, you know the headache of thermal variance. On a Sidel SBO Series 2, that usually comes down to a power mismatch. Here is the reality: when you mix lamps with different wattages, or throw in a few aging filaments, your preforms don’t heat evenly. It’s a mess. We built our replacement lamps to hit the OEM power specs exactly. No guessing, no drifting. Just consistent heat. The Power Problem You need the same wattage across the whole oven to keep your heat profile stable. Simple as that. But here’s the catch: if a lamp is rated for 2500W but only puts out 2300W because the filament is cheap, that whole zone underperforms. We use high-precision tungsten so the voltage-to-wattage ratio actually stays where it belongs. This means your PET resin hits that sweet spot—the glass transition temperature—without accidentally scorching the plastic. Built for the Grind We use heavy-wall quartz glass because these things take a beating from rapid thermal cycling. They need to be tough. Plus, we use standard R7s/Sk15 connectors. You just pop them in. No rewiring, no fuss, no wasted time. The quartz is crystal clear to let the shortwave IR through, but a word of advice:**keep your reflectors spotless.**Dust is a killer. It’ll tank your efficiency way faster than the lamps will ever wear out. Real-World Tips These are made for high-cycle shops. You can swap them during your scheduled downtime and you won’t have to go messing around with your PLC heating curves. One thing to watch out for, though. If you’re running these at max output, your cooling blowers are working overtime. If those blowers are clogged with gunk, the oven gets too hot, and you’ll burn out the lamp ends early. Keep the air moving, and these lamps will take care of the rest.
