Sidel SBO 20 Series 2 Heater: The Real Deal Drop-In for Your PET Blow Molding Line
We make the heating lamps that live inside the biggest names in packaging. And when it comes to the Sidel SBO 20 Series 2, you’re not just getting a spare part. You’re getting the same internal specs, the same materials, and the same performance as the original. Straight up. This is a drop-in replacement, built from the ground up to keep your PET blow molding line running the way it should.
Power, Voltage, and Fit: Why the Numbers Matter
The SBO 20 Series 2 heater was built around one specific idea: the right heat, in the right place. It runs at 400V and hits 2500W of power across a 300mm active length. Those numbers aren’t random. The 400V keeps the current manageable on the factory floor. And the 2500W? That’s what gives you the heat density needed to soften PET preforms fast—fast enough to keep cycle times tight. Space is tight in there, too. The 300mm tube is sized to slip into that cramped spot, with an overall length that clears the clamp and blow station without fighting the geometry. Go shorter or underpowered, and you’ll feel it. Longer heat-up times. Bottle walls that start to drift. Not the kind of surprise you want mid-run.
What It’s Made Of: Halogen, Quartz, and a Smart Coating
Inside, you’ve got a halogen-filled quartz tube. The halogen cycle keeps the element clean, so output stays steady over time. And the quartz body takes the thermal shock of rapid on/off cycles without cracking. Then there’s the reflective coating. It focuses radiant energy forward, so you waste less heat and keep nearby parts cooler. And the R7s connector? It’s simple, solid, and meant for real work. Two contacts that handle high current without arcing. Wire it up, lock it down, and it stays put. No fuss.
Real-World Performance—And the Trade-Offs You Should Know
On a PET blow molding line, the heater has to deliver steady radiant heat without scorching the preforms. Our SBO 20 Series 2 lamp matches the original footprint and output profile, so heating stays predictable and bottle quality stays consistent. Installation? Straightforward. No re-engineering the clamp or reflector. You swap it in and get back to work. Now, here’s the honest part: it runs hot. 2500W at 400V will do that. That means your machine’s cooling and airflow need to be in shape. If ambient temps climb, lamp life takes a hit. Keep the cooling system clean, and you’ll get stable output and fewer surprise stops. We build these lamps to the same tolerances we supply to the major brands. That’s how we can stand behind the spec—and the reliability—when the machine is humming on the shop floor.
