Getting Your Sidel SBO Heater Lamps Right

If you’re swapping out infrared lamps in a Sidel SBO, you already know that just finding a tube that fits the length isn’t enough. It’s a bit more finicky than that. To keep your bottles looking right and your heat profile steady, you have to get the voltage, wattage, and spectral output to line up exactly with what the machine expects. The deal with heat density Most SBO setups use short-wave IR lamps because they punch through the PET wall fast. We usually look at high-wattage tubes running at 230V or 400V. Here’s the thing: a 400V lamp shoves way more energy into the preform in a shorter amount of time. That’s how you keep your line speeds where they need to be. If you accidentally drop the voltage or wattage, you’re going to start seeing “cold spots.” That’s a headache you don’t want, because it leads to weird wall thickness in your finished bottles. The nitty-gritty on fit and feel We use high-purity quartz glass and halogen gas fills. Why? Because it stops the filament from burning out way too early. As for the connectors—usually R7s or SK15—we make sure they’re built to tight tolerances. They should just slide right into the sockets. No forcing, no shoving. If you have to fight to get it in, you’re risking an arc-over at the terminals, and nobody wants to deal with that. Real-world installation tips When you’re wiring these up, do yourself a favor:don’t mix old and new tubes in the same oven zone. It sounds like a small detail, but old lamps drift in resistance over time. New ones hit their peak output the second you flip the switch. If you mix them, you get a thermal imbalance that messes with your quality. One last thing. These high-output lamps get incredibly hot. If your cooling fans are clogged with dust or just plain dying, those lamps will practically bake your reflectors. Take a minute to clean those reflectors every time you swap a lamp. You want that IR energy hitting the preform, not soaking into the machine frame. It’s a simple step, but it keeps the whole assembly living longer.
