A Better Way to Handle Your Krones Contiform Heaters
Let’s be honest: OEM part costs for Krones Contiform lines can be a total gut punch to your maintenance budget. We’ve spent a lot of time building infrared heating lamps that do the job just as well as the originals, but without the eye-watering price tag. These aren’t some cheap, generic tubes you found in a catalog. We’ve engineered them specifically for the heavy lifting required in PET preform heating. The heat side of things If the heat isn’t distributed just right, you end up with those annoying pearlescent defects in your bottles. Nobody wants that. To stop it, we’ve dialed in the wattage and voltage so the heat flux feels exactly like what your machine expects. When you’re pushing 2000W+ through a quartz tube, you get that instant, aggressive ramp-up you need for high-speed runs. But here’s a heads-up: running at peak capacity is hard on your power supplies. If your electrical panels are getting old, you’ll probably notice the tubes burning out faster. It’s worth taking a look at your power stability if you’re seeing a high failure rate. Fit and finish We use high-purity quartz glass because it can take the shock of rapid heating and cooling without cracking. We also added specialized coatings that shift the infrared spectrum. This means the heat actually sinks into the preform wall instead of just scorching the surface. As for the fit? It’s easy. Whether you need R7s or Sk15 connectors depending on your machine’s age, they just slide right in. No rewiring the oven. No messing around with the lamp holders. You just swap them and get back to work. A few tips for the long haul Our lamps perform like the OEM versions, but their lifespan really comes down to how clean your oven is. Dust is the enemy here. When gunk builds up on the quartz, it creates hot spots, and those hot spots kill the tube. If you keep your reflectors polished and your tubes clean, these things will last. You get to keep your cycle times exactly where they need to be, but you stop overpaying for the name on the box.
