Getting Your Sidel IR Lamps Right
Let’s be honest: swapping out heating lamps in a PET blowing machine is usually a headache. You’re dealing with tight spaces, picky power draws, and the constant worry that something won’t quite fit. We wanted to fix that. We built our IR lamps to slide right into Sidel systems—everything from the old-school SBO models to the new Matrix series—so you don’t have to mess around with machine mods.
Getting the heat just right
Here is the tricky part about PET preforms: you need the core to be soft enough to blow, but you can’t scorch the outer wall. It’s a balancing act. We spec our tubes to hit the exact wattage and voltage your Sidel oven expects. By using high-wattage shortwave halogen filaments, these things heat up fast. Really fast. That’s how you keep up with high-speed cycles without breaking a sweat. One quick tip, though. If you’re running these at full blast, your oven’s ventilation has to keep up. If your airflow is clogged, the tubes will overheat, and you’ll burn through your filaments a lot faster than you’d like.
No more “making it fit”
We’ve all been there—buying a “replacement” part only to find you need a shim or a weird adapter to make it actually stay in place. We hate that. That’s why we make these to the exact footprint of the Sidel line. Whether you’re using R7s or those specialized SK sockets, the pins just line up. You pull the old tube out, pop the new one in, and you’re back in business. No adapters, no brackets, no fuss.
The nitty-gritty on materials
We use high-purity quartz glass because nobody wants their lamps clouding over after a few weeks. Some of our tubes even have special coatings. Instead of wasting energy by heating up the oven walls, these coatings push the heat directly into the PET. It’s just more efficient. But a word of warning: be careful when you’re installing them. Use gloves. If you leave fingerprints on the quartz, those oils will burn into the glass, creating hot spots that can ruin the tube. Keep it clean, and they’ll last.
