Getting Your Sidel Matrix Heating Just Right
When you’re replacing lamps in a Sidel SBO Series 2, “close enough” usually isn’t good enough. If the temperature ramp-up isn’t a perfect match, you’re going to feel it in your production numbers. That’s why we don’t guess. We build our replacement lamps to mirror the exact wattage, voltage, and length of the originals. The goal is simple: your PET preforms hit the right temperature without you having to touch a single machine setting. The headache of the “heat curve” Here’s the thing about swapping lamps. If the voltage or wattage is even slightly off, your heat density shifts. If a lamp runs a bit too cool? You end up with under-blown bottles. Too hot? You’re looking at burning or that annoying pearlescence in the plastic. We spec our tubes to fit the SBO Series 2 electrical footprint exactly. Because the infrared emission stays consistent across the whole quartz tube, you don’t have to waste your afternoon tweaking oven zones just to make a generic lamp work. It’s all in the details We use high-purity quartz and specific halogen gas fills to keep the operating temperature steady. And we know how frustrating it is when parts don’t actually fit. Our connectors are designed for a true drop-in replacement. They slide into your sockets easily—no forcing, no swearing. We also obsess over where the filament sits. If it’s off by just a few millimeters, you get cold spots. That ruins the uniformity of the heat, and that’s where the trouble starts. A quick tip for the floor These lamps are built for high heat density and fast cycles. But there’s a catch. Running at peak wattage puts a lot of stress on your oven’s reflectors. If yours are pitted or oxidized, you won’t get that 1:1 performance, no matter how good the lamp is. Do yourself a favor: give those reflectors a good clean before you wire up the new lamps. It ensures the heat actually hits the plastic instead of bouncing around the oven.
