Getting Your Krones Contiform S Heat Profiles Just Right

If you’re running a Krones Contiform S, you already know that everything comes down to the infrared energy. Those lamps have one job: soften the PET preforms just enough so they stretch perfectly. But when the OEM prices start climbing, it gets frustrating. You need a replacement that actually works without having to rebuild your entire oven. The numbers matter. We build our lamps to hit the exact voltage and wattage your Contiform S oven expects. Most of these setups use high-wattage shortwave IR emitters. Whether you’re dealing with 230V or 400V depending on the zone, the filament has to hit a very specific temperature to heat that PET fast. Here’s the thing: if the wattage is off by even 5%, you’re in trouble. You’ll either end up with uneven wall thickness because the plastic didn’t get hot enough, or you’ll see that annoying pearlescence in the bottle because you cooked it. Built for the grind These aren’t flimsy bulbs. We use heavy-wall quartz glass because these things go through a brutal cycle of heating and cooling. To keep the filament from evaporating and dying early, we fill them with halogen gas. And don’t worry about the installation. We use standard R7s or Sk15 connectors. They just slide right into your existing sockets. No rewiring, no headaches. A quick word of advice These are direct swaps. Just pop them in during your scheduled downtime and you’re good to go. But a heads-up: high-density shortwave lamps put out a lot of intense, localized heat. I know it’s tempting to bump up the wattage to squeeze out a few more cycles, but be careful. If you do that, your cooling fans have to be spotless and working perfectly. If the air around those lamp holders gets too hot, the sockets will carbonize and your lamps will burn out way faster than they should. Honestly? Just stick to the specs. It’s the best way to keep your heat profile stable and your production running smooth.

The Krones Contiform S Heating Tube: What It’s Really Made Of, and Why It Matters for Your PET Blow Molding

Let’s talk about the heart of your Contiform S blow molding line: the heating tube. Specifically, the Krones Contiform S shortwave infrared heater. Its whole reason for being is simple—get your PET preforms hot, fast, and evenly. The kind of heat that lets you stretch them perfectly every single time, without ever scorching the material.

High intensity NIR for Krones Contiform

On a Contiform line, preform heating is the one bottleneck you can’t treat like a guessing game. Let the heating tunnel drift, and you’re staring down uneven wall thickness, blown bottles, and scrap. That’s why high-intensity near-infrared (NIR) emitters for the Krones Contiform are built around one idea: keep the heat profile repeatable, and keep it aligned with the machine’s original intent. What actually matters under the hood We spec NIR emitters to get the Contiform into its heating window fast, with power matched tightly to the OEM heater circuits. The payoff is a controlled temperature rise and a stable thermal field across the preform neck and body. Quartz elements give you snappy response, and the emitter geometry is chosen to keep heat distribution even—no hot streaks, no cold spots. In practice, you get a preform temperature curve that behaves the same cycle after cycle. Why this fits the Contiform in the first place The Contiform stretch blow molder needs predictable preform heating to keep stretch ratios and cycle times in balance. With the right NIR power profile, the heating tunnel recovers quickly after jams and changeovers, and you see fewer rejects from uneven wall distribution. Energy use drops because the emitters heat on demand and hold steady without overshoot. Swapping them in is straightforward: match the R7s connector type, line up the mounting dimensions, and program the power setting to the machine’s heater control. A few shop-floor realities NIR intensity is sensitive to preform color and material thickness, so initial setup should include a temperature scan along the preform length. Double-check the voltage and amperage limits of your Contiform heater output—mismatched power will shorten emitter life. And keep reflectors clean and aligned; if they’re off, the heat pattern shifts, and the bottle can go off-spec.
