Getting the Heat Right on Your Krones Contiform S

Keeping a Krones Contiform S running smoothly is all about a balancing act. You need enough heat to get the job done, but you don’t want to burn through your lamps every few weeks. When OEM replacement costs start to bite, you need a solution that just works. No tinkering, no downtime—just a lamp that hits the same thermal marks without slowing down your cycle. Let’s talk power. The Contiform S uses shortwave infrared lamps to soften those PET preforms fast. We make sure our lamps match your original voltage and wattage exactly. Why? Because if you go too low, you’ll end up with uneven wall thickness in your bottles. If you go too high, you’re looking at scorched preforms. It’s a tight window. Just double-check your power supply and cooling before you swap things out, because high-density heat can really push your oven reflectors to the limit. The build quality We use high-purity quartz glass. It has to be tough to handle the constant “on-off” thermal shock of a production line. Depending on which oven generation you’re running, these usually come with R7s or Sk15 connectors. They snap right in, which means no loose connections and no scary arcing at the terminals. For certain zones, we add a special coating to the quartz. It helps the infrared light soak deeper into the PET, so the preform spends less time in the oven and more time becoming a bottle. A pro tip for the shop floor These are direct replacements. You won’t need to rewire anything or mess with the holders. But here is the thing:quartz hates oil. If you touch the glass with your bare hands during install, the oils from your skin create tiny hot spots. Those spots are where the glass eventually cracks or fails. It’s a frustrating way to lose a lamp. Grab some gloves, or give the tubes a quick wipe with isopropyl alcohol before you fire up the machine. Your filaments will thank you.

Generic KRONES infrared heater

Introduction

We built the Generic KRONES infrared heater for one reason: to stop the headache of proprietary heating parts shutting down your shop floor. This universal infrared lamp is a straight-up, drop-in swap for over 95% of blow molding machines worldwide. It gives you the raw heat you need for PET preforms, without forcing you to rewire half the machine.

Technical Deep-Dive

At the heart of it is a high-voltage, high-power design. It runs on 400V and cranks out 2500W, focused across a 300mm active length. That’s how you get the heat density required to bring PET preforms up to temperature fast. The high voltage isn’t just a random choice. It means you can use lower-amp wiring, which cuts down on voltage drop over distance and keeps the electrical footprint tight on the machine.

Krones infrared heater SK15

When your Krones blow molder starts to drift on preform heating, you know it immediately. Unplanned downtime. Scrap climbing. And the sting of paying OEM prices just to keep the line turning. The heating tunnel is the heart of stretch blow molding—if the infrared emitters aren’t pulling their weight, cycle speed slips and bottle quality goes sideways. What matters under the hood The Krones SK15 infrared heater is built around short-wave quartz infrared. It responds fast and holds tight control across the heating zones. It’s engineered to match Krones OEM dimensions and electrical specs, with standard R7s connectors and the right voltage and wattage for stable, repeatable output. In practice, that means quicker warm-up, steady emitter temperature even at high speed, and consistent preform wall temperature before the blow step. Why it plays nice on a Krones line On a Krones blow molder, the SK15 drops in as a direct-fit replacement that keeps your heating profile intact. You get stable heating that supports higher throughput without chasing drift, and the energy draw stays within the machine’s original design parameters. Less output swing means fewer rejects from weight variance and weak stretch lines, and the emitter life helps stretch the run windows between changeouts. A few shop-floor reminders Installation is straightforward, but verify the machine’s voltage and connector type before ordering—mismatched wiring will cost you output and shorten emitter life. Keep reflectors clean and aligned; even a good emitter underperforms if the heat isn’t focused onto the preform path. Plan replacements during scheduled maintenance windows so you don’t get blindsided by an unplanned stop.
