On the line, a Krones stretch blow molder pushing 14,000–18,000 BPH lives and dies on predictable preform heating. When the heating bulb starts to fade, you know it instantly—uneven wall thickness, blown bottles, and the line slowing down while the controller chases temperature. The Krones heating bulb 3000W is built to keep that heating tunnel stable, cycle after cycle. What matters technically This bulb is a short-wave infrared halogen emitter, engineered to match the OEM thermal profile of Krones blow molders. It throws 3000W of concentrated heat and warms up fast, so the preform surface hits the target temperature quickly and repeatably. The quartz envelope and the R7s connector interface are specced to drop into the original socket and reflector geometry, giving you the same beam pattern, the same hot zone, and the same control response. In practice, that means less temperature drift across the tunnel and fewer alarms from the heating controller. Why it works in the real world Swapping in an underperforming bulb for the Krones heating bulb 3000W goes straight at downtime and scrap. We’ve seen plants nail down stable heating within one shift after the change, then hold consistent bottle weight and top load. Energy use drops, too, because the emitter hits setpoint faster and holds it with fewer corrections—on a high-speed line, that can translate to roughly 8–12% less heating energy per 1,000 bottles. Maintenance intervals stretch as well, with many installations running 5,000+ hours before output starts to drift. The payoff is fewer changeovers, fewer stoppages, and more bottles per hour. A few shop-floor details Installation is straightforward, but the heating tunnel has to be clean. Dust on the reflector and residue on the bulb surface distort the infrared pattern and create hot and cold spots. Match voltage and connector type to the machine spec—mismatched voltage will shorten lamp life and throw the heating curve off. Handle the quartz bulb with a clean, dry cloth; fingerprints bake on and cut output. If you run 24/7, keep spares on hand so you can swap during a planned break and avoid extended shutdowns.
