When the heating tunnel on your Krones blow molder starts drifting, preforms never hit the right stretch temperature. You see it immediately—output drops, and the reject pile grows. The 780mm infrared lamp was built to drop into your Krones machine as a straight replacement for the OEM emitter, with no guesswork. What matters technically It’s a short-wave halogen emitter engineered for Krones blow molders: 780mm long to match the standard heating zone, and an R7s base for a direct plug-in. The output is tuned to heat PET preforms fast, getting the preform surface up to stretch temperature quickly while the core catches up evenly. The quartz envelope gives you high radiant density, and the filament geometry keeps the heating profile steady across the whole tunnel width. In practice, that means fewer hot spots, fewer cold seams, and cycle times that stay stable. Why it works on a Krones line Krones lines have a tight heating window. If the lamp starts underperforming, you end up slowing the conveyor just to keep bottles in spec—throughput takes a hit. This 780mm lamp puts the heat curve back where it was designed to be, so you can run at line speed again. Changeovers recover faster, bottle quality becomes more repeatable, and energy use per part comes down because the emitter heats on demand with minimal thermal lag. Swap is clean: one lamp, same footprint, back to spec. A few shop-floor reminders Double-check the lamp voltage matches your machine’s supply. Before you install, inspect the reflector—if it’s degraded, the heat pattern will be off even with a brand-new lamp. Also confirm compatibility with your specific heating module and control strategy. Running outside the rated voltage shortens lamp life and shifts the spectrum, so stick to the specs. When it’s all lined up, the 780mm infrared lamp keeps your Krones blow molder heating the way it should, shift after shift.
