Stop Fighting Your Krones Contiform S Oven
There’s nothing more frustrating than pulling a batch of bottles and seeing uneven walls or weird deformations. It usually means your heat distribution is off. When that thermal field starts to drift, you aren’t just wasting energy—you’re tossing perfectly good preforms into the scrap bin. We’ve been there. That’s why we built our replacement IR bulbs to plug those specific gaps. Getting the heat right The Contiform S is picky. It needs a very specific balance of wattage and voltage to keep the preform at the right temperature. We use high-wattage, short-wave lamps because they punch through the PET material fast. We also made sure these tubes fit the OEM footprint exactly. Why? Because if the angle is off by even a fraction, the IR radiation misses the mark. Just a heads-up: keep an eye on your power supply. If your voltage jumps around, your output dips, and you’ll burn through bulbs way faster than you should. Built to take the heat We use heavy-wall quartz glass. It has to be tough to handle the constant heating and cooling cycles without cracking. You’ll also notice we use a halogen cycle. This stops the tungsten filament from baking onto the glass and creating those annoying “dark spots” that ruin your heat uniformity. The best part? They’re a total drop-in replacement. You just use your existing connectors and you’re back in business. No need to rip apart your oven housing or modify anything. Real-world results Our lamps do what the OEM ones do, but they tighten the tolerance on the heat output across the whole tube. For you, that means a more consistent thermal field and way less time spent fiddling with machine adjustments. But here’s the thing: if you crank up the heat density to shave time off your cycles, your cooling fans are going to work harder. If your vents are clogged with dust, these lamps will run too hot and die early. Keep your airflow clear. Your quartz will thank you, and your bottles will look a lot better.
