Getting Your Sidel SBO and Matrix Heaters Right

If you’ve spent any time on a PET blowing line, you know the headache of pearlescence or those annoying thin walls. It all comes down to the heat. If your thermal profile is off by a hair, you’re looking at a pile of scrap. That’s why we build our preform heater lamps to fit Sidel systems perfectly—whether you’re still running the old-school SBO lines or you’ve moved up to the Matrix series. It’s not just about the size. Matching the OEM footprint is the easy part. The real trick is the power. We spec our lamps to hit the exact wattage and voltage your oven expects. We use high-wattage shortwave infrared lamps because you need that raw heat density to keep your cycle times fast. But a word of caution: when you’re running high-voltage tubes, things get hot. Fast. Make sure your ventilation is actually clear. If it’s clogged, you’re just asking for your circuitry to fry. The nitty-gritty on the glass We use high-purity quartz and halogen gas fills. Why? Because it stops the filament from evaporating too quickly. It keeps the light steady and makes the lamps last longer. We also use standard R7s or SK15 connectors so you can just pop them in and go. We’ve spent a lot of time mapping the exact dimensions of the SBO and Matrix series. Here’s the thing: a gap of even 2mm can create a cold spot on the preform. That leads to uneven stretching, and suddenly your bottles aren’t looking right.Precision matters. Real-world maintenance These lamps live on the shop floor. They take a beating from constant heating and cooling. To stop arcing, we put extra focus on the contact points where the lamp meets the holder. If you’re swapping these into an older SBO machine, do yourself a favor and check the wiring for brittleness before you flip the switch. You won’t need to rewire your boards or mess with the chassis—these just slide right in. One last tip:**use a lint-free cloth.**If you touch the quartz with your bare hands, the oils from your skin create hot spots. That’s the fastest way to burn out a brand-new lamp.

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.

Stop Fighting Your SIPA Oven: Let’s Fix Those Heat Spikes

If you’re running a SIPA rotary machine and seeing bottles come out with weird wall thickness or deformations, you know the frustration. You spend hours tweaking settings, but the heat just won’t stay consistent. Here’s the secret: it’s usually not the machine acting up. It’s the lamps. A lot of shops try to save a few bucks by mixing generic infrared tubes with OEM parts. But when the power doesn’t match perfectly, you get cold spots in some areas and burn-outs in others. It’s a mess. The trick is in the power match. We make sure every single lamp in your oven pulls the exact same wattage. Why? Because even a tiny 5% difference shifts the thermal load. That might not sound like much, but it’s enough to throw off the balance of your preform. We build our tubes to hit your specific SIPA voltage and wattage exactly. That way, the heat stays uniform as the machine rotates. Simple as that. It’s also about the little things—like the glass and the plugs. We use high-purity quartz because it can take the hit of rapid heating and cooling without cracking. Then there are the connectors—R7s or SK15. Most people ignore the plugs, but that’s actually where things usually go wrong. A loose fit creates resistance. Resistance creates heat. And that heat melts your housing. We keep our tolerances tight so the lamp just drops in and locks. No wiggle room, no melted plastic. A quick heads-up on the trade-offs. If you’re running high-speed lines, you probably want high-wattage shortwave lamps. They ramp up fast. But there’s a catch. Pushing all that power into a small space puts a lot of stress on your cooling blowers. If your airflow is clogged or your blowers are tired, the ambient heat will kill your lamps—no matter how good the quartz is. Keep your vents clear. The goal here is to give you a drop-in replacement. You swap the old tubes, wire them up, and you’re done. You get a flat thermal profile and you can finally stop messing with the timers every time a lamp starts to fade.
