Making Quartz Heaters That Actually Fit Your Sidel Machine
If you’ve ever swapped heaters in a PET blowing machine, you know the struggle. The biggest headache isn’t the electrical work—it’s the physical fit. When a tube is off by just a couple of millimeters, or the connector doesn’t quite seat right, you’re asking for trouble. You risk an arc or, even worse, a shattered tube. It’s a nightmare. That’s why we built our quartz series to be a true drop-in replacement for Sidel gear. Whether you’re still running the old SBO lines or you’ve moved up to the Matrix series, these just work. Getting the fit right We don’t guess on the specs. We match the length and diameter of the OEM tubes exactly. This means the lamp sits right where it should—centered in the oven—without rubbing against the reflectors. And we know the reality of high-capacity plants: voltage swings happen. If you’re pushing high wattage to keep your cycle times fast, you can’t have a tube that burns out the moment you crank the power. We use heavy-wall quartz because it can actually handle that kind of thermal stress without giving up. No rewiring, no fuss Most of these machines use those picky end-caps. We make ours to fit your existing sockets perfectly. You just pull the old one out and slide the new one in. No messing with the machine frame. No hunting for custom brackets. It’s as simple as that. A quick word on heat Here is the thing about high-density quartz: they soak the PET preforms with heat fast, but that puts a lot of pressure on your oven’s ventilation. If you decide to bump up the wattage to speed up production, just make sure your cooling blowers can keep up with the extra ambient heat. If they can’t, your electrodes will start to degrade way faster than they should. At the end of the day, we obsess over the tolerances so you don’t have to. Your Matrix or SBO tubes should slide in without you having to force them. You get the heat you need, and your hardware stays safe.
