Introduction
So, your SIG Blomax line keeps chewing through tubes. It’s frustrating, right? You replace them, and a few weeks later, you’re back to square one. The answer isn’t just another standard tube. We built a different kind of fix: a structurally reinforced, high-intensity NIR halogen tube. It’s a true drop-in replacement, engineered to last longer and handle the brutal thermal and mechanical stress that wipes out standard lamps on those high-speed PET lines.
Let’s Get into the Details: Power, Voltage, and Size
Here’s the thing about high-intensity NIR heating—it’s all about precision. These tubes run at high voltage, typically 400V, to deliver the wattage you need for rapid PET heating. The active heating length is 300mm, which concentrates all that power into a tight space. That’s how you get the heat density to soften preforms fast, without dragging out the heating zone. This is the only way to keep up with high-output blowing. But, and this is important, it also means the lamp and its surroundings run hotter. So, plan your machine’s cooling and airflow accordingly. You’ve got to protect the reflector and the components right next to it from overheating.
The Build: Materials, Coating, and Connections
We started with a quartz envelope, optimized to pump out that shortwave NIR. Inside, a halogen fill keeps the filament performance stable, even on those long, grueling runs. Then there’s the reflector coating. It’s specialized to direct energy forward, cutting down on wasted heat. This means more energy actually gets into the preform, and you protect nearby sensors and seals from the heat. For the installation, we use R7s bi-pin connectors. They provide a secure, high-current connection, making the lamp a true plug-and-play replacement. The base and mounting points are reinforced, too. They’re built to stand up to vibration and thermal shock—the two things that murder standard tubes on a continuous production line.
Real-World Results: Solving the Problems on Your Line
On Krones Contiform and SIG Blomax machines, that heating zone takes a beating. Standard lamps crack, lose output, or just fail at the connector. Our reinforced design cuts down on those unplanned changeouts. It means less downtime and a heating consistency you can actually count on. You get fewer line stops. The bottle quality becomes more predictable. And the replacement cycle finally matches the reality of 24/7 operation. If your line is burning through tubes, this is the engineered alternative. It’s not just built to fit. It’s built to run.
