Stop fighting with your Sidel heaters

If you’ve ever dealt with PET preforms, you know the struggle. If your infrared heat isn’t hitting exactly where it needs to, you end up with wonky wall thickness in your bottles. It’s a headache you just don’t need. That’s why we make heating lamps specifically for Sidel systems—everything from those old-school SBO lines to the newer Matrix series.

Customized IR module for PET factory

Let’s be honest: keeping Krones Contiform machines running is expensive. Especially when you look at the bill for OEM parts. It feels like a tax just for wanting your equipment to work. That’s why we built our own IR heating modules. They’re designed to be simple drop-in replacements. You get the same factory specs, but you stop overpaying for the name on the box. Getting the heat right With PET blowing, it’s all about balance. You need to hit the preform wall with exactly the right amount of energy without scorching the neck. We spec our lamps for high wattage and specific voltages so the heat flux keeps up with your cycle time. If you’re running high-speed lines, you need that rapid ramp-up. It’s the only way to keep pace. But here’s a tip: if you’re pushing more heat, your ventilation and cooling blowers have to be spotless. If your airflow is choked, those lamps will burn out way faster than they should. The nitty-gritty stuff We use high-purity quartz glass with a special coating. Why? Because it shifts the emission spectrum. Instead of the IR energy bouncing off the plastic, it actually sinks in. Then there are the connectors—usually R7s or Sk15. We use heavy-duty contacts because thermal expansion is a real pain. Nobody wants to deal with arcing or loose fits after a few hundred cycles. It just works. Putting them to work The best part is that these modules fit right into your existing Contiform oven. No rewiring the cabinet. No messing around with lamp holders. You just swap them out. Since we calibrate the electrical load and spectral output, your heating profile stays exactly the same. You still get that consistent wall thickness in every bottle, but your cost-per-bottle actually goes down. It’s a much easier way to protect your margins.

Getting Your SACMI Oven Up to Temp—Fast

If you’re running a SACMI rotary blow molder, you know the pace is relentless. Everything happens in a blink. Your preforms need to hit a very specific temperature in a matter of seconds, or you’re in trouble. When your lamps take too long to warm up or can’t keep pace with high RPMs, you start seeing those annoying wall thickness issues or that cloudy “pearlescence” in the bottles. It’s frustrating, and it kills your yield. Cutting out the lag We built our replacement lamps to fix that. We tweaked the tungsten filament and the quartz thickness to get rid of the “thermal inertia”—which is just a fancy way of saying we made them heat up faster. When you swap these into your rotary oven, you’ll notice the ramp-up is way snappier. That means less scrap in the bin during start-ups and changeovers. It just works. The fit is simple Nobody wants to spend their afternoon messing with wiring looms or hacking away at lamp holders. We made these drop-in replacements. The dimensions and connectors match the original gear exactly, so you just plug them in and get back to work. We also use high-purity quartz. Why? Because it lets the infrared heat go straight into the PET preform instead of getting trapped in the glass. A word of caution on lifespan Here’s the honest truth: when you push for faster start-ups and higher heat, you’re putting more stress on the filament. You get the speed you need for high-volume runs, but you have to keep an eye on your voltage regulators. If you try to “over-volt” these lamps to squeeze out even more heat, you’re going to burn them out early. Don’t do it. And please, keep your cooling fans clean. If the oven housing gets too hot, even the best quartz in the world will start to degrade. Good airflow is the only way to make sure these lamps actually last through a full production run.

Getting Your Sidel Matrix Heaters Right

Here’s the thing about swapping out OEM lamps in a Sidel Matrix oven: the biggest headache isn’t the installation. It’s the temperature curve. If the heat density or the IR spectrum is off by even a tiny bit, your preforms won’t heat evenly. That’s how you end up with wonky wall thickness or that annoying pearlescence in your bottles. Nobody wants to deal with that.
