The Halogen Lamp That Finally Fixes the Heat Headache on Your KHS Line
Let’s talk about the heating headache on your KHS blow molding line. You know the one—uneven heat that makes you chase rejects, mess with settings, and just plain waste time. We built this halogen infrared lamp to be a straight-up, drop-in fix for the Sidel Combi SF300, and it plays nice with KHS machines, too. If your line is struggling with inconsistent heating, this lamp goes right after the real problem: the way heat spreads across the PET preform. No more hot and cold spots. Just even, reliable warmth.
Why the specs actually matter
This lamp runs at 400V and has a 300mm heating length. That isn’t random. The 400V rating keeps the current manageable, so your heater controls and wiring don’t get hammered. Less stress. Fewer surprises. And the 300mm length? It’s about matching the heating zone of the SF300 perfectly. You get a heat profile that lines up with the preform, so you don’t end up with scorching near the neck and cold zones along the body.
Built to perform, built to last
Inside, you’ve got a quartz tube with a halogen fill. That combo gives you steady output and quick thermal response. The halogen gas lets the filament run hot while staying stable, so the heat across the tube stays consistent. Quartz handles rapid on-off cycles and won’t crack when production stops and starts. It just keeps going. Then there’s the R7s connector—a simple bi-pin end-cap that locks in place and makes a solid, low-resistance connection. Install is a no-brainer. No adapters. No fiddling with terminal blocks. Just plug it in and go.
What this means on your KHS machine
On KHS blow molders, even heating is everything. It means stable bottle weight, fewer rejects, and less scrap. This lamp spreads heat evenly across the preform, so your parison stretch and wall thickness stay on target. But here’s the thing: it’s a 400V, high-wattage lamp, so it delivers serious heat density. That’s great for performance, but it means your machine’s cooling and airflow need to be in good shape. If airflow is blocked, the lamp can run hotter than it’s meant to. Give it the environment it was designed for, and you get a clean, reliable heat profile that keeps your line moving. No drama. Just work.
