Sidel Infrared Radiator Module: The Tough Drop-in for SIG Blomax Lines
We built this Sidel infrared radiator module for one reason: to stop those frustrating tube failures on your SIG Blomax PET blowing line. It’s a structurally reinforced, long-life replacement that drops right in and keeps your line moving.
The power, voltage, and fit—explained like you’re standing next to the machine
We set it up to deliver steady heat without taking up extra space. The 400V input means lower current for the same wattage, so the wiring stays cooler and you lose less voltage along the way. The 300mm length lines up perfectly with the standard hot zone on Blomax machines. That gives you even heating across the bottle neck—no messing with the reflector cavity. And the wattage is tuned for PET stretch blowing, so the preform hits the right temperature right before the blow pin engages.
What’s inside—quartz, coating, and a connector that just works
The tube uses quartz with a halogen-filled environment. That keeps the filament stable and the output consistent over time. A reflective coating on the outer jacket pushes energy forward and shields nearby parts from stray heat. The connector is SIG-compatible, so you wire it into the existing holder without any modifications. And the ends are reinforced to handle repeated heating and cooling, vibration, and the quick replacements that happen on a live line.
Real-world reliability—because downtime isn’t an option
On a Blomax line, infrared modules get hammered. Standard tubes crack at the ends or fade in output, and that means unplanned stops. This replacement is built for continuous duty, so burnouts drop and the oven section stays consistent. And because it’s a drop-in, changeover is fast. One honest note: the high heat density needs proper airflow and cooling around the module. If the machine’s cooling isn’t in spec, the service life will suffer. For SIG Blomax operators, this module is a practical, no-drama upgrade that helps you keep uptime steady.
