Can new lamps actually squeeze more life out of an old Contiform S?

If you’re running an older Krones Contiform S, you know the struggle. You’re chasing target cycle times, but the machine just isn’t keeping up. You start seeing those annoying “cold spots” on the preforms, and suddenly your wall thickness is all over the place. It’s frustrating. The quickest way to get that capacity back? Swap out those tired, degraded lamps for some high-spec infrared replacements. The deal with heat density Here is the thing about the heating oven: it relies on short-wave infrared to get deep into the PET. But as lamps age, they don’t put out the same kind of heat they used to. We build our replacements to hit the exact voltage and wattage the original machine asked for. Why? Because if you try to “cheat” by throwing in a higher wattage tube to force more heat, you’ll probably just burn the surface of your preforms. It’s a balancing act between how much heat you’re throwing and how fast that conveyor is moving. Quartz and the “little things” We use high-purity quartz glass. It lasts longer and doesn’t burn out nearly as fast. Then there are the connectors—usually R7s or SK15. They might seem like a small detail, but a loose fit is a nightmare. It creates resistance, which leads to arcing, and before you know it, you’ve got melted sockets. Plus, we’ve coated the quartz to bounce the heat back toward the preform instead of letting it soak into the oven walls. Less waste, more heat where it actually matters. A quick heads-up before you swap These are drop-in replacements. No need to rewire anything or call in a specialist for a total overhaul. It’s pretty straightforward. But wait—there is one catch. When your lamps start working efficiently again, your oven’s ventilation has to keep up. If your cooling fans are clogged with dust or just plain dying, the oven is going to get too hot inside. That’s how you end up with crystallized PET. So, do yourself a favor: check your airflow first. Once that’s sorted, new tubes mean fewer rejects and a lot more bottles hitting the pallet every hour.

Getting Your Krones Contiform S Back Up to Speed

If you’re running an older blow molding machine, you probably know the frustration of the “oven bottleneck.” It’s a pain. Your preforms just aren’t hitting the right temperature consistently, and suddenly your cycle speed tanks. You’re losing money every minute that machine slows down. We build our replacement IR bulbs to fit the Contiform S footprint perfectly. We don’t just guess at the specs; we focus on heat density and spectral output so you can actually get your production capacity back. The nitty-gritty on power Here is the thing about IR lamps: it’s all a balancing act between voltage, wattage, and the length of that quartz tube. For the Contiform S, we stick with high-wattage short-wave emitters. Why? Because short-wave radiation punches through PET plastic way faster than the long-wave stuff. We use higher voltage ratings to keep the current draw low. This is huge for anyone running 24/7 because it keeps your wiring from overheating. Just a heads-up: if you crank the wattage too high to chase more speed, make sure your oven’s ventilation can actually handle the heat. If it can’t dump that extra warmth, you’re risking your electronics. Built to last (and fit) Nobody wants to replace bulbs every few weeks. We use heavy-wall quartz glass so the tubes don’t bow when things get hot. Plus, the filaments are halogen-cycled. This stops the tungsten from evaporating too quickly, which means the lamp actually lasts. And then there are the connectors. We use standard R7s or Sk15 because they lock in tight. A loose connection is a nightmare—it creates resistance, which leads to arcing and burnt-out sockets. Our connectors are designed to handle the natural expansion that happens when the lamp hits full heat. What this means for your floor Swapping out old, tired bulbs for calibrated emitters basically resets your oven’s heat profile. You get a much more even temperature across the preform body. The result? Way fewer rejects. No more dealing with those annoying thin walls or pearlescence. The best part is that it’s a simple drop-in replacement. You don’t have to mess with the cabinet wiring or call in a specialist. Just swap the bulbs, recalibrate your heating zones, and get back to work.
