Stop Blaming Your Old Sidel SBO—It Might Just Be the Lamps
If you’re running an older Sidel SBO and your cycle times are dragging, your first instinct is probably to assume the machine is just tired. It’s an old workhorse, right? Maybe it’s time for a new one. But before you spend a fortune on a new line, look at your infrared lamps. Usually, the bottleneck isn’t the machine itself—it’s just that the tubes have worn out. Swapping them for the 2002406262 spec is often all it takes to get that heat flux back and soften your PET preforms the way they should be. Why the 2002406262 spec actually matters Here’s the thing: the SBO system relies on short-wave IR to get deep into the PET wall without scorching the surface. We build these lamps to hit the exact voltage and wattage your oven expects. If you try to cut corners with a lower wattage lamp, your preforms won’t hit that “sweet spot” temperature in time. You’ll end up with cold spots or uneven walls in your bottles. Not a great look. The nitty-gritty on materials We use high-purity quartz glass because these tubes take a beating. The thermal shock from constant start-stop cycles would crack cheaper glass. Plus, we fill them with halogen gas. That stops the quartz from darkening over time, meaning your heat stays strong for thousands of hours. And about the connections—we keep them standardized. Why? Because a loose fit is a nightmare. It creates resistance, which leads to arcing, and before you know it, you’ve burned out a socket. Getting them installed (and a few warnings) These are drop-in replacements. You don’t have to mess with your wiring or spend a weekend rewiring the oven. It’s pretty straightforward. But wait—there is a trade-off. When you bump up the heat density to speed up production, your cooling blowers have to work harder. If you’re pushing the oven to its limit with new lamps, keep an eye on your exhaust fans. If the cabinet gets too hot, you risk warping the reflectors. Once that happens, your energy efficiency goes right out the window. One last tip: match the lamp to your preform weight. If you put too much wattage into a lightweight preform, you’ll scorch the plastic. Stick to the 2002406262 parameters and you’ll get a stable, repeatable blow every single time.
