Stop Overpaying for Your Krones Contiform Lamps
Let’s be honest: OEM parts are expensive. If you’re running a Krones Contiform line, you know exactly what I mean. The costs add up fast, and it starts to feel like you’re paying a premium just for the brand name on the box. We decided to fix that. We make IR blowing lamps that do the exact same job as the factory ones—delivering that precise shortwave heat to your PET preforms—but without the massive markup. The nitty-gritty on power These aren’t your average lightbulbs. They’re built for high-voltage industrial environments. We’ve dialed in the wattage-to-length ratio so the heat hits exactly where it needs to. If you’re running a 400V system, you need filaments that can actually handle the load. We use heavy-duty tungsten because it stays stable. It doesn’t just flicker or burn out the moment things get intense. But a quick heads-up: high wattage means they ramp up fast. Just make sure your cooling blowers are actually doing their job. If your airflow drops, these lamps will cook the PET, and you’ll end up with those annoying burnt zones or that cloudy pearlescence in your bottles. Glass and connectors that actually last We use high-purity quartz glass. Why? Because it doesn’t soak up the IR energy itself. Instead, it pushes all that heat outward, straight into the preform. For the connectors, we stick with R7s or Sk15. They handle the “breathing” of thermal expansion much better than a soldered joint ever would. Plus, we offer coated versions. These act like a mirror, bouncing the heat back toward the center of the oven instead of letting it waste away against the machine walls. Getting them into your machine Swapping these in is easy. You wire them up exactly like the original parts. We’ve kept the tolerances on the diameter and length tight, so you won’t be fighting to get them into the lamp cages. No forcing, no jamming—they just fit. Now, look, these tubes take a beating in a 24/7 production cycle. That’s just the nature of the beast. While we build them to hold their output for thousands of hours, the filament will eventually age. That’s normal. But by switching to our versions, you’re cutting your maintenance costs way down without sacrificing the quality of your bottles.
