Better Infrared Bulbs for Your Krones and Sidel Blow Molders
If you’ve spent any time around a PET stretch blow molder, you know the nightmare of uneven heat. One minute everything is fine, and the next you’re staring at wall thinning or that annoying pearlescent haze on your bottles. It’s a headache you don’t need. That’s why we make infrared heater bulbs that actually fit. Whether you’re running old-school SBO lines or the newer Matrix series, we’ve got you covered.
No “making it work” required
There is a big difference between a bulb that almost fits and one that just slides right in. We don’t want you spending your afternoon modifying an oven or messing with the hardware. We’ve mapped out the exact footprints of the original gear. For the Krones Matrix and SBO setups, we match the length and the connector geometry perfectly. We use standard R7s and Sk15 bases, so you can just wire them up and get back to work. No adapters, no hacks. And we’re strict about the power. If your machine calls for 230V or 400V, we give you exactly that. If the wattage is off, you’re either going to under-heat the preform or burn through your lamps way too fast. Neither is a win.
The grit behind the glass
We use high-purity quartz glass because it can handle the shock of rapid heating and cooling without cracking. These are shortwave halogen lamps, but we’ve added specific coatings to the quartz. Here’s the trick: we filter the IR spectrum so the energy hits the PET material, not the oven walls. It’s about putting the heat where it belongs. Just a heads-up—these tubes put out a massive amount of heat. Make sure your ventilation is clear. If the airflow is blocked, that heat builds up and starts eating away at the internal electrodes. Keep it breathing, and the bulbs will last.
Just swap and go
The best part? These are true drop-in replacements for Sidel and Krones systems. Because we match the spectral output of the original lamps, you don’t have to spend hours rewriting your heating profiles or tweaking settings. You swap the bulb, set the power, and hit start. It’s simple. No downtime, no guesswork, and no stress.
