Stop Overpaying for Krones Contiform Heating Lamps
Let’s be honest: OEM heating lamps are expensive. When you’re running Krones Contiform lines, those replacement costs can really eat into your budget. We’ve put together a drop-in replacement that does the exact same job as the Nissei ASB or Krones specs—giving you the thermal output you need without that “brand name” tax. The nitty-gritty on power These lamps are built for high-voltage circuits because you need a ton of wattage in a tiny space. If you’re running a 400V system, you’re getting the heat density required to soften PET preforms in a matter of seconds. But here’s the thing: your power needs to be stable. If your voltage is jumping all over the place, the filament takes a beating. That’s how you get premature burn-outs. Keep the power steady, and these tubes will hold up through rapid cycling. Glass, coatings, and connections We use high-purity quartz glass to make sure the shortwave IR actually gets through. Most of these use R7s or Sk15 connectors. It’s not just about the fit—it’s about making sure you have a tight electrical connection so you don’t deal with arcing at the base. We also apply specific coatings to the quartz. This shifts the emission spectrum so the heat actually penetrates the preform wall. You want the plastic soft and ready, not scorched on the surface. Getting them installed Swapping these out is a breeze. Just pull the old tube, double-check the socket for any carbon buildup, and wire it up. Since we’ve spec’d these for the exact dimensions of the Contiform oven, you don’t have to mess around with the reflectors. Just plug and play. One quick warning, though. High-wattage tubes put off a massive amount of ambient heat. If your cooling fans are clogged or just plain dying, no lamp—no matter who made it—is going to last. You’ve got to keep the airflow moving to stop the lamp envelopes from overheating. That balance between the heat going in and the air moving out is what determines how long your lamps actually live.
