Better Lamps for Your Krones Contiform S and Sidel Matrix
If you’ve spent any time around PET blow molding, you know the struggle. Get the heat slightly off, and suddenly you’re dealing with thinning walls or that annoying pearlescence in the preform. It’s a headache. That’s why we spent the time engineering infrared lamps that actually fit. No guessing games. We built these specifically to slide right into Krones Contiform S and Sidel Matrix series machines. The technical side of things We kept the voltage and wattage exactly where the OEM wants them. Whether you’re clinging to a classic SBO setup or running a brand new Matrix line, the power matches. If it doesn’t, your lamps burn out way too fast. Simple as that. Inside, we use high-density tungsten filaments. They push heat into the shortwave spectrum, which means your preform gets hot quickly. The best part? You aren’t baking the internal chassis of your oven while you do it. No one likes a difficult install We focused heavily on the mechanical fit. These are true drop-in replacements. We used standard R7s and SK15 connectors, so you can just wire them up and go. No modifying holders, no hacking away at the machine. We also treated the quartz glass with specific coatings to bounce the heat inward toward the preform. It’s a smarter way to use energy. We’ve already mapped out the dimensions for Sidel and Krones ovens. You won’t be shimming holders or messing with reflectors. It just fits. A few tips from the field Here’s the thing: high-wattage tubes put out a massive amount of heat. Check your cooling fans. If they’re clogged with dust or just plain broken, your lamp housing is going to take a beating, and that quartz envelope will pop sooner than it should. And a pro tip? Don’t swap every single lamp in the bank at once. We recommend a staggered replacement schedule. It keeps your heat profile consistent across the machine and saves you from a sudden “cold spot” shock to the system.
