Getting Your Sidel SBO and Matrix Heaters Right
When you’re blowing PET, heat consistency is everything. But nobody wants to spend their weekend modifying an oven chassis just to get a new lamp to fit. That’s why we make our quartz heater tubes as simple “drop-ins.” Whether you’re running an old-school SBO or a modern Matrix, these are built to fit the space you already have. The fit has to be spot on. Let’s be honest: a “compatible” tube is a piece of junk if the ends don’t seat right. We obsess over the millimeters here. Why? Because if a tube is a tiny bit too short, you get cold spots at the ends. If it’s too long? Snap. You’ve just broken a piece of expensive glass during installation. We make sure they slide right into your reflectors without any forcing or stress. Power and heat Moving from SBO to Matrix usually means a change in how much power you’re pushing. We match our filaments to the exact voltage and wattage your specific series needs. If you’re running high-speed lines, you need those high-wattage tubes to ramp up quickly. Just a heads-up, though: check your power supply first. If you try to push too much current through an aging SBO wiring harness, you’re asking for tripped breakers or a burnt-out lamp. Choosing your material We use high-purity quartz because it can handle the shock of rapid heating and cooling without cracking. Now, you’ll see coated tubes out there. They’re great for absorbing infrared heat with certain PET resins, but they can flake off if your oven’s airflow is wonky. We offer both clear and coated options—it really just depends on what your preforms are made of. The real-world install The best part? No drilling. No weird brackets. No custom adapters. You just pull the old lamp out, slide the new one in, and wire it up. It’s that simple. It keeps your downtime short, so you can get back to actually producing bottles instead of fighting with your hardware.
