Why the best blow molders call us when the heat is on
Let’s cut through the noise. We make the ceramic lamp holders and infrared elements that live inside Sidel blow molding ovens. This isn’t about brand loyalty. It’s about keeping your oven zones rock-solid when the line is running full tilt. If the temperature dips and can’t snap back fast, your whole line slows down. That’s the reality.
The guts of it: power, voltage, and size
We pack a lot of heat into a small space. Our infrared lamps typically run at 400V, up to 2500W, in a 300mm tube. That means intense, focused energy right where you need it—on the PET preform heating zone—without wasting heat where it doesn’t matter. Because the wattage is high and the body is short, the lamp ramps up fast and recovers quickly after door cycles or brief stops. But here’s the catch: that kind of heat demands a cooling system that’s up to the task. If the cabinet airflow is too small, you’ll see parts wear out early and temperatures drift.
What’s inside: materials that earn their keep
At the core is a halogen-filled quartz tube. The halogen gas keeps the filament stable and cuts down on blackening, so output stays steady for thousands of hours. The quartz body takes the shock of rapid on/off cycles without cracking. Then we pair that with a ceramic lamp holder that can handle the heat without breaking down. Ceramic holds its dielectric strength when things get scorching, so you don’t get leakage or insulation failure. The R7s connector gives you a firm, clean connection that wires up quickly and consistently. Less wiggle, fewer hot spots, and easier maintenance.
How it feels on the line: fewer stops, more parts
Inside a Sidel oven, the environment is punishing—high cycling, hot ambient air, and constant vibration. Our element is built as a straight drop-in that matches the thermal profile and electrical setup. The result? Stable heating and fewer surprise stops. When lamps last longer, you spend less time chasing zone issues and more time running good parts. Just remember: with this level of power, you need solid cooling and proper clearances. Plan the heat path, or the system will work against itself. We build for that reality—so the oven keeps running, and your maintenance team can breathe.
