Stop Overpaying for Krones Contiform Heating Lamps
If you’re running Krones Contiform machines, you already know the drill. The thermal profile has to be spot on. If it’s off by even a hair, you end up with stress marks or weird wall thickness in your PET bottles. It’s a headache you don’t need. But here’s the real pain: the cost of OEM lamps. When those prices spike, it eats into your margins fast. You need a replacement that actually works—meaning it hits the same wattage and spectral output—without messing up your blow cycle. The nitty-gritty on heat We built our lamps to match the original Krones electrical footprint exactly. We usually stick with a 400V setup. Why? Because high voltage lets us cram more wattage into a shorter tube. That means more infrared intensity. It gets your PET preforms up to that glass transition temperature quickly. If you try to cheap out with a lower-wattage bulb, your cycle slows down. And in this business, slower cycles mean fewer bottles per hour. That’s money leaking out of the building. Quartz and the “Plug-and-Play” part We use heavy-wall quartz glass. It’s tough. It keeps the tube from bowing when things get scorching hot. Plus, we added a specialized coating. Instead of wasting heat by baking your oven walls, the coating pushes that energy right into the PET material. For the fit, we use standard R7s or Sk15 connectors. They just click in. You can swap them out in minutes during your next scheduled teardown without any fuss. A quick word of caution These lamps put out a massive amount of heat. It’s great for speed, but it’s a bit of a double-edged sword. All that thermal load puts a lot of pressure on your cooling fans. If your vents are clogged or a fan is dying, these lamps will overheat at the end-caps and burn out way too soon. Just keep your airflow clear, and the quartz will last much longer. At the end of the day, switching to these replacements just makes sense. You get the same heat penetration and distribution as the big-brand parts, but you stop paying the “OEM tax.”
