Stop Chasing Burned-Out Bulbs on Your PET Line
If you’re running SIG Blomax or Krones Contiform S lines, you know the headache of tube burn-outs. It’s frustrating. One minute you’re hitting your targets, and the next, you’re dealing with thermal shock or a quartz envelope that just gave up. We got tired of seeing those lines go down, so we built replacement IR bulbs that actually hold up to the grind of high-speed blowing. The heat is the hard part. These lamps are built to match the wattage and voltage your Contiform S oven expects. We use high-wattage shortwave IR emitters because you need that intense heat to soften PET preforms in a heartbeat. The goal is to get the heat deep into the plastic without scorching the surface. But here is a pro tip: if you push the wattage to speed up your cycles, your cooling blowers are going to feel it. If your airflow is clogged with dust or grime, it doesn’t matter how tough the bulb is—the ends will eventually fry. Keep those blowers clean. Why these actually last Most standard bulbs bow when they get hot. When the glass bends, the filament shifts, and that’s usually where the failure starts. To fix that, we used a heavier-wall quartz glass. It stays straight. It stays strong. We also obsessed over the connectors. We’ve all seen those loose fits that cause an arc and burn out the terminal. We tightened the tolerances on these so they snap in securely. No gaps, no arcs, no surprises. Getting them on the floor The best part? You don’t have to rewire a single thing. These are drop-in replacements that fit the exact footprint of your SIG or Krones racks. It’s a simple swap that means fewer “broken tube” alarms and way fewer line stops. You get to spend less time climbing into ovens and more time actually shipping bottles. One last thing—before you pop these in, double-check your voltage stability. A nasty power spike will kill any lamp on the market, no matter how thick the glass is. Keep your power clean, and these bulbs will take care of the rest.
