Sidel SBO 40 Series: Giving Old Machines New Life with Infrared Halogen Heat
We hear it all the time on the shop floor: “Can we really get more out of an old blow molder just by changing the heaters?” The short answer? Yes. But only if the replacement is dialed in—on heat, on power, on fit. The Sidel SBO 40 Series 1 infrared lamp was built to slide right into older machines, giving them the heat punch and control needed to run modern PET cycles.
Power, Voltage, and a Surprisingly Small Footprint
This lamp runs on 400V and pulls up to 2500W, all packed into a tidy 300mm tube. That’s not by accident. High voltage keeps the current down, which means less energy lost in the lines—and more usable wattage in a short space. The payoff is a high watt-density profile that heats preforms fast and even, so cycles can move along quicker. But there’s a trade-off you can’t ignore: that kind of heat density needs serious cooling. If your machine’s airflow is weak, the lamp will run hotter than it should, and you’ll shorten its lifespan. Keep the airflow right, and it just works.
What It’s Made Of: Halogen, Quartz, and the Right Connection
Inside, you’ve got a halogen-filled quartz envelope built to keep the filament steady when things get scorching. The halogen chemistry helps keep tungsten where it belongs—on the filament—so the output stays consistent for thousands of hours. The quartz handles thermal shock and stays clear enough to let infrared through cleanly. And the R7s connector? That’s the secret to a true drop-in replacement. It locks in alignment and carries the load securely, so you can wire it up fast without wrestling with sockets or brackets.
Why It Matters on the Floor: PET Blow Molding Without the Headache
This setup was made for PET blow molding upgrades. The infrared profile hits the preform wall directly, so preheat time drops and temperature stays steady across the neck and body. For you, that shows up as less scrap, quicker changeovers, and the confidence to run more demanding bottles without scrapping the whole machine. The SBO 40 Series 1 is the kind of upgrade you can bolt in and get on with your day—older blow molder, modern throughput, no full line overhaul.
