Getting Your Sidel SBO and Matrix Heaters Right
If you’re running a fleet of PET blowing machines, you know the headache of trying to keep heat profiles consistent. It’s a balancing act. To get it right, you need lamps that actually fit the original specs—no guesswork, no “close enough.” We make infrared heater lamps that slide right into the whole Sidel lineup, whether you’re still rocking the old-school SBO systems or you’ve moved up to the Matrix series. The fit is everything Moving from an SBO to a Matrix isn’t just a small jump; the oven architecture and power needs change completely. That’s why we map every single lamp to the specific machine footprint. Length, wattage, voltage—it all matches your original wiring. It’s a simple drop-in replacement. You won’t have to mess around with the lamp holders or tweak your power supplies. You just put them in and get back to work. Quartz that can take the heat We use high-purity quartz glass because these things go through a lot of thermal shock during rapid cycling. You need something that won’t crack under pressure. These lamps use shortwave infrared to punch through the PET preform quickly. Plus, we offer coated versions. These push the heat back toward the preform instead of letting it bleed away, which saves you a bit on the energy bill. One quick tip: these tubes have a high wattage density, which is great for faster cycle times. But keep an eye on your ventilation. If your cooling fans are clogged with dust, that heat builds up and can burn out your lamps or warp your reflectors. Keep it clean. Reliability and the “Cold Spot” Problem We use standard industrial connectors because a loose connection is a nightmare. It creates resistance, which leads to overheating, and eventually, you’re looking at melted sockets. Not a fun way to spend a Tuesday. Here is a pro tip: replace your lamps in matched sets. If you mix and match, you end up with “cold spots” in the oven. That’s how you get uneven wall thickness in your bottles. Swap the old tubes, wire them up, and run your heat soak tests. Because the dimensions are exact, nothing rattles or shifts when the machine hits high speeds. It just stays put.
