Getting Your SACMI and Krones Lamps to Heat Up Faster
When you’re running a SACMI rotary blower at full speed, you don’t have a second to waste. The window to heat that preform is tiny. If your lamps lag—even by a fraction of a second—you end up with “cold spots” or wonky wall thickness in your bottles. It’s a headache you don’t need. That’s why we built our lamps for the Krones Contiform 3 and SACMI lines to cut out that lag entirely. Why they start so fast It mostly comes down to the filament. We use a low-inertia tungsten filament that hits its operating temperature way faster than the standard industrial tubes you’re probably used to. We also tweaked the wattage-to-length ratio. The result? The lamp hits peak IR emission in milliseconds. No more worrying about the first few preforms in a cycle coming out under-heated. It just works. The tech under the hood We use high-purity quartz glass because these lamps take a beating, cycling from off to scorching hot over and over again. Plus, we added specific coatings to push the emission toward shortwave IR. Why does that matter? Because shortwave radiation digs deeper into the PET preform, and it does it faster. But here’s a pro tip: when you’re pushing this much energy into such a small space, your oven reflectors take a hit.**Keep them polished.**If they get dirty, that heat bounces right back into the lamp ends and fries the seals. Easy swap, no stress You won’t need to rewire your racks or call in a specialist. These are drop-in replacements. They match the physical and electrical specs of the OEM lamps exactly. We also beefed up the end-caps. Rotary machines vibrate a lot, and that vibration usually kills the vacuum seal on cheaper tubes. Ours hold tight, which means you can spend more time running your line and less time dealing with maintenance shutdowns.
