Stop Fighting With Your PET Blowing Lamps

Let’s be honest: the last thing you want when a lamp blows is to spend three hours figuring out if a replacement part actually fits your machine. You just want the line moving again. That’s why we built our infrared bulbs to be “drop-in” replacements. Whether your machine is a brand-name powerhouse or something a bit more niche, there’s a 95% chance our lamps will slide right in without any fuss. The Heat Side of Things Most of these systems run on high voltage and heavy wattage. If you’re using a 230V or 400V setup, the real magic happens in the wattage-to-length ratio. Take a 2500W tube in a 300mm space. That’s a massive amount of energy hitting your preforms in a matter of seconds. It’s the only way to get that perfect soften without scorching the plastic. Just a heads-up, though—when you’re pushing that much heat, make sure your cooling fans are actually doing their job. You don’t want your oven housing baking itself. Built to Last (and Actually Fit) We use heavy-wall quartz glass because rapid heating and cooling is brutal on equipment. To keep the filament from burning out too fast, we fill them with halogen gas. It simply lasts longer. As for the plugs? We stick to R7s and SK15 connectors. They’re the gold standard for a reason. We keep the tolerances tight so you can slide the bulb into the socket and feel it click into place. No forcing it, no praying it doesn’t spark—just a clean fit. Getting Back to Work These bulbs use shortwave infrared. Instead of just heating the surface of the PET wall and hoping for the best, the heat actually penetrates deep into the plastic. The best part is the setup. Since we match the dimensions and electrical specs of the big OEM brands, you can forget about rewiring control boards or hacking your lamp holders. You swap the dead tube, lock it in, and flip the switch. Easy.

Introduction

Here’s the deal. We built these PET preform heater lamps to be a simple, plug-and-play upgrade for Sidel blow molding lines. The whole point? To swap out old, tired heaters without having to rewire or rework the machine. Seriously, it’s a straight drop-in. We’ve got you covered, whether you’re running a classic SBO series or the newest Matrix platform.

The Nitty-Gritty

Getting a preform hot, fast and evenly is the name of the game. So we fine-tuned the power density to hit that sweet spot. The lamps are engineered to spread consistent heat across the whole surface of the preform, which means carefully balancing voltage and wattage. We also match the quartz tube’s shape to the exact dimensions of each Sidel machine’s heater bank. The result? Heat gets delivered where it needs to go, with no cold spots. And that’s huge, because it keeps your bottle walls consistent and the material strong.

R7s halogen lamp for PET preheat oven

On the floor, minutes are money. When the preheat oven starts hunting for temperature, preforms come out inconsistent, and you’re spending more time swapping lamps than making bottles. We built the R7s halogen lamp for that exact headache—engineered to match the original specs of your PET preheat oven, without the OEM price. What matters under the hood This is a short-wave infrared halogen emitter, in a standard R7s form factor, cut for the tight geometry and thermal profile of PET preheat tunnels. The quartz envelope takes rapid thermal cycling in stride, and the tungsten filament responds fast—so you get stable, repeatable heating across the preform wall. We match the original wattage, voltage, length, and base type, so it drops straight into existing sockets and reflectors. The output is tuned for PET: quick energy absorption, minimal surface scorch, and consistent stretch behavior once the blow molder takes over. Why this fixes the bottleneck In stretch blow molding, the oven is the first pinch point. If heating is slow or uneven, you end up compensating with slower cycles, higher energy draw, or settings that push rejects. The R7s restores the designed heating curve, so you can run the machine the way it was intended—stable preform temperature, predictable biaxial stretch, and fewer pinholes and crystallization issues. Replacement cost comes down because you keep the same oven configuration and avoid a full retrofit. Energy use drops because the lamp hits setpoint fast and holds it with less swing. Field notes for a clean install Installation is straightforward—check socket condition, clean the reflector, and make sure the voltage matches the label. These run hot, so let them cool before handling and keep reflectors free of dust and flaking. If the oven has older sockets or corroded contacts, fix those first; poor contact causes flicker and uneven heating. For best life, run the oven within its rated range and avoid the thermal shock that comes from constant start-stop cycles.

High power infrared lamp 3000W PET

Out on the line, the blow molder is trying to tighten the cycle, but the preform heating keeps fighting you. Underheated necks, walls that run too hot, and output that drifts—most of the time, you can trace it back to the heating tunnel. That 3000W high-power infrared lamp for PET isn’t just a replacement part. It’s the control point that makes repeatable heating possible.

What matters, technically

We built this emitter around a short-wave infrared source, delivering 3000W of focused radiant power so it responds fast and holds steady. The quartz envelope handles thermal shock, and the standard R7s connector drops it straight into a lot of heating modules. You get predictable spectral output and stable temperature profiles across the preform surface—exactly what you need when you’re running thin-walled or high-stretch PET designs. Output stays consistent over long runs, and we size the lamp to match the OEM tunnel geometry so the heating pattern doesn’t wander.
