Let’s be honest: keeping Krones Contiform machines running is expensive. Especially when you start looking at the price tag for OEM replacement parts. It feels like a tax just for wanting your equipment to work. That’s why we make our own PET preform heater lamps. They’re designed to be drop-in replacements. You get the same performance you’re used to from the factory, just without the “brand name” markup. The science bit (made simple) Here is the thing about heating preforms: you need that shortwave infrared radiation to hit the PET wall just right. If it’s off, you end up melting the outside before the inside is ready. We’ve tuned our lamps specifically for high-voltage industrial setups. By balancing the wattage and voltage, we hit that sweet spot where the heat flux is fast enough to keep your cycle times tight. One quick heads-up, though. If you’re using our higher-wattage tubes, make sure your cooling blowers are actually doing their job. If your cooling is weak, these lamps can get a bit too hot for the oven housing. Built to actually last We use high-purity quartz glass because we’re tired of seeing lamps burn out way too early. Inside, there’s a halogen cycle that keeps the filament centered. This means your heat stays consistent from one end of the preform to the other. And don’t worry about the installation. We use standard R7s or Sk15 connectors. You just plug them into your existing sockets and you’re good to go. No rewiring, no modifications, no headaches. What this does for your bottom line At the end of the day, this is about your cost per bottle. We obsess over the spectral output so your preforms hit that glass transition temperature (Tg) evenly. When you avoid those annoying “cold spots,” you stop getting uneven wall thickness during the stretch-blow process. You get the same heating curve you’ve always had, but your maintenance budget doesn’t take a hit. These tubes live a hard life in 24/7 production, so we built them for stability. You’ll spend less time swapping lamps and more time actually producing.
