Getting Your SIPA and Sidel Lamps Right
If you’ve ever tried to swap out infrared lamps in a PET blowing machine, you know it’s not as simple as just matching the wattage. Whether you’re running a SIPA SFR 12 or a Sidel—anything from the old SBOs to the new Matrix series—the real trick is keeping that thermal profile steady without having to rebuild your entire oven. The fit has to be perfect. We build these lamps to be true drop-in replacements. I’m talking exact lengths and exact voltages. Why? Because if a lamp is off by even a couple of millimeters, it won’t sit right in the reflectors. When that happens, you get hot spots and cold spots. Then you start seeing those annoying wall thickness variations in your bottles. It’s a headache you don’t need. That’s why we obsess over the heat density across the whole quartz envelope—it keeps things consistent, even when your rotary blow molding is running at full tilt. Quality that actually lasts. We use high-purity quartz because nobody wants to deal with a premature burnout in the middle of a shift. We also make sure the connectors match your OEM sockets perfectly. No adapters, no rigging, no “making it work.” You just plug them in. For the Sidel Matrix crowd, we put a lot of thought into the spectral output. You need that shortwave radiation to punch through the PET wall fast. Plus, we use specific coatings that push the heat toward the preform and keep it away from the machine’s guts. It keeps the hardware happy. A few tips for the install. These work across the entire Sidel and SIPA range, so you can just swap them out during your usual maintenance window. But here’s a heads-up: if you decide to bump up the wattage, keep an eye on your cooling fans. More power means more heat load. If you don’t tweak your airflow to match, you risk cooking the wiring insulation over time. Just a little something to check so you don’t end up with a bigger project on your hands.
