Stop Overpaying for Krones Contiform Maintenance

Let’s be honest: keeping Krones Contiform lines running is expensive. Especially when you’re staring at the bill for OEM replacement parts. When your IR lamps burn out, you don’t need a lecture on brand loyalty—you just need a lamp that works. We build IR lamps to the exact specs of your machine so you get the same heat profile and consistency without that “brand name” tax on your invoice.

Replacement lamp for PET oven

Getting Your Sidel Matrix Ovens Back in Sync

Here is the thing about swapping out OEM infrared lamps in a Sidel Matrix oven: it’s a bit of a gamble. If you get a lamp that’s even slightly off in wattage or spectral output, your temperature curve shifts. That’s when the headaches start. Your PET preforms either don’t get enough heat—which means they won’t stretch right—or they get too hot, leaving you with that annoying pearlescence and thin walls. Nobody wants to deal with that. Matching the electrical side of things We don’t believe in “close enough.” We build our replacement lamps to 1:1 specs. It isn’t just about the length of the bulb. We dive into the exact voltage and wattage the Matrix system expects. By making sure the tungsten filament’s resistance matches the original OEM parts, the current draw stays exactly where it should be. What does that mean for you? Your power controllers won’t start throwing errors, and your heat ramp-up time stays consistent. It just works. The secret is in the quartz The Sidel Matrix needs a very specific kind of short-wave infrared radiation to actually get through the PET wall. To make that happen, we use high-purity quartz glass. Cheap glass absorbs too much energy. It basically wastes heat by warming up the lamp itself instead of the plastic. We match the coating and filament density so the IR emission hits the same peaks as the original. That’s how we keep your temperature curve stable after the swap. Real-world installation These are true drop-in replacements. We use the same connector footprints, so you can just wire them up. No hacking the oven housing or “making it fit.” One quick tip, though. These lamps put out some intense heat. While the lamps are solid, your reflectors might not be. If your reflectors are dirty, they won’t bounce the heat into the preform. You’ll be tempted to crank up the power to compensate, but that’s a trap—it just burns out the filaments faster. Keep those reflectors clean and stick to the original voltage settings, and your lamps will last much longer.

Customized IR module for PET factory

On any PET line, the heating tunnel calls the shots. Under-heated preforms give you weak bottles and blown rejects. Over-heat them, and you’re wasting material and chasing unstable stretch ratios. Most of the time, the root cause is an IR module that’s just plain mismatched—wrong watt density, wrong spectral response, wrong mounting geometry. You end up throttling back the line speed just to compensate.

R7s halogen heater lamp for PET preheat

On a running blow molding line, the heating tunnel is where you win or lose the shift. If preform temperature starts to drift, stretch becomes inconsistent, you start seeing crystallized spots, and scrap piles up fast. We built the R7s halogen heater lamp for PET preheat to stop that drift where it starts.

What matters, technically

The lamp uses short-wave infrared, so it responds quickly and gives you tight control right there in the heating tunnel. We match the R7s base and the quartz envelope to the OEM footprint, so it drops straight into Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB blow molders without any rework. Typical ratings cover 100–240V, and power density is matched to preform wall thickness. The energy profile stays repeatable shift after shift. The filament layout and reflector geometry are tuned to spread heat evenly across the preform body and neck, cutting down hot spots and cold zones that cause bursts or weak shoulders.
