Getting Your Krones Contiform Blowers Running Right

If you’re running an SMI SR 12 blower, you already know the struggle. You need that infrared heat to be just right—enough to soften the PET preforms, but not so much that you end up with cloudy plastic or weird wall thickness. But here’s the rub: OEM replacement lamps can be ridiculously expensive. We’ve fixed that. We make drop-in replacement lamps that hit the exact same thermal footprint and spectral output as the originals, without the eye-watering price tag. The Power Side of Things These lamps aren’t your average lightbulbs. They run on high-voltage circuits to pump out the intense short-wave radiation needed to heat things up fast. We build our tubes to handle the specific wattage and voltage loads your Contiform system demands. Just a heads-up: because we’re packing high wattage into a small quartz envelope, it gets incredibly hot. Keep an eye on your power supplies. If your voltage is jumping around, you’re going to fry the filaments way sooner than you should. Built to Take a Beating We use heavy-wall quartz glass because these lamps go through a lot of thermal shock during rapid cycling. They’d crack if they weren’t toughened up. Plus, we use R7s (or similar) snap-in connectors. This is a lifesaver during maintenance. You can just swap the tubes out and get back to work without having to mess around with the oven’s wiring. One more thing: we use a halogen cycle to stop tungsten from building up on the glass. It keeps everything clear. If you notice the glass looking cloudy, your heat transfer is dropping, and your cycle times will start to climb. It’s a sign it’s time for a change. Making it Work in Your Shop These fit right into your existing setup and line up perfectly with your reflectors. It’s a simple swap. But here is a pro tip: if you’re pushing these lamps to their absolute max wattage, your cooling fans are going to work overtime. Check your ventilation. If the airflow is sluggish, the lamp ends will overheat, and your electrodes will give out early. We’ve focused on matching the infrared wavelength to the PET absorption peak. Why? Because it stops energy from going to waste. You get the heat where you need it, and nowhere else.
