Fixing Those Annoying Heat Spots in Your KOSME KSB 4000

Ever notice your PET preforms stretching unevenly? Or maybe the wall thickness is all over the place? It’s frustrating. Usually, when the heat field starts drifting, your first instinct is to think the whole oven needs a teardown. But here’s the thing: most of the time, it’s just the infrared lamps wearing out.

Let’s talk about the heat

We designed our replacement lamps for the KSB 4000 to slot right into the original electrical setup. No guesswork. We build them to handle high-voltage loads so the wattage stays steady from one end of the quartz tube to the other. Why does that matter? Because it kills those “cold spots” at the ends of the tube that mess up your bottles. If you’re running a high-capacity line, you’re probably chasing heat density. A higher wattage lamp pushes more IR energy into the preform. It works great, but it does put more stress on your power supply. Just double-check that your transformers can handle the draw, or you’ll be replacing burnt-out parts way too often.
