Introduction
We built this replacement lamp for one reason: to fit the Sacmi SBF 12/24 heating zone like it was born there. It’s a straight swap for Krones Contiform lines, made for anyone who wants to keep performance steady while bringing maintenance costs down. Same heat, same footprint as the original. Swap it in, and the line keeps moving. No fuss. No surprises.
What it’s really doing under the hood
Here’s the practical part: it runs on 400V and hits 2500W, giving you the kind of even, predictable heat that keeps preforms moving at the right pace. The active length is 300mm, which matches the standard zone setup, so the heat profile stays consistent without you having to rework the oven. That power isn’t random. It’s chosen to get preforms up to temperature fast enough to keep your cycle time where it should be. But—and this matters—2500W packs a lot of heat into a tight spot. Your cooling and ventilation have to keep up. If the cabinet airflow is struggling, you’ll start seeing components age faster and temperatures wobble. That’s the part no one wants.
The build that takes the heat
We went with a quartz tube and a halogen fill because it responds quickly and stays steady, even when it’s switching on and off over and over. The coating is tough enough for the heating chamber, and it resists the kind of contamination that can dim the element over time. The R7s connector makes the hookup straightforward, so the lamp sits square and makes solid contact every time. And yes, it’s plug-and-play. Change it out fast. No rewiring. No modifying fixtures. Just get it back online and keep going.
Why it matters on the Contiform line
On a Krones Contiform, this lamp lives in the preform heating stage—where consistent heat is the difference between good bottles and scrap. When you run a replacement that matches the specs, you keep repeatability without paying for the original badge. The payoff is simple: lower cost per part, and fewer unplanned stops for lamp changes. You’re getting the same performance envelope as the factory lamp, with the same mounting and electrical fit. Reliability, without the premium price tag. That’s the kind of maintenance win that actually shows up on the bottom line.
