Sidel SBO 16 Heating Lamp: The Straightforward Swap That Calms KHS Heat Issues
We built the Sidel SBO 16 heating lamp for one simple reason: when your KHS blow molding machine starts to drift on heat, you need a replacement that just drops in and gets the job done. No drama. No rework. Its mission is straightforward—deliver steady, repeatable heat to the PET preform so your bottles come out consistent, without you chasing hot spots and cold spots all shift.
Power, voltage, and geometry—tuned to work together
This lamp runs at 400V and pulls 2500W, packing serious heat into a small footprint. That wattage isn’t random—it’s matched to what PET preforms actually need, so you hit the right thermal load without overdriving the heating zone. And the 300mm length? That’s deliberate too. It lines up with the heating chamber so the heat field covers the neck and body evenly. Here’s the neat part: running 400V at 2500W lowers the current for the same power, which eases stress on the wiring and cuts voltage drop along the line. Just keep one thing in mind—this kind of heat density means your machine’s cooling has to be up to the task. The blower and airflow path need to keep the chamber in the sweet spot for PET.
What’s inside: halogen, quartz, coating, and connectors that make sense
Inside, you’ve got a halogen capsule inside a quartz envelope. The halogen keeps the filament stable even at high temperatures, so output stays steady over time. The quartz handles thermal shock and stays optically clear, which makes the radiant heat predictable. We added a selective coating on the quartz to shape the emission spectrum and reflect heat back toward the preform. The result? Better temperature uniformity across the zone. On the ends, it uses R7s connectors—quick to lock in and built to maintain solid contact. And if you need it, the Sk15 base option gives you a direct drop-in fit on compatible KHS fixtures. No rewiring. No fiddling with the holder.
Why this matters on a KHS blow molding line
On KHS machines, uneven heating shows up as weak necks, uneven wall thickness, and bottles that blow out. That’s the kind of problem that eats into uptime and makes every run feel like a gamble. The SBO 16 is dimensioned and interfaced to work as a direct replacement on KHS. You swap it in, and you get a tighter thermal field—meaning more repeatable heating across the preform. That translates into fewer rejects, fewer line stops, and less time spent tweaking zone temperatures. If your KHS machine has been struggling with heating uniformity, this lamp is the straightforward, spec-matched upgrade that helps you keep the process stable—where it matters most: on the shop floor.
