On the floor, preform temperature that drifts or isn’t nailed down will eat your line efficiency alive. On a Krones Contiform 3, uneven heating shows up fast—crystallization, haze, a weak neck finish. Next thing you know, rejects pile up and the schedule slips.
What matters, technically
We spec the lamp as a short-wave infrared halogen emitter matched to the Contiform 3 heating zone geometry. It runs at the OEM-typical power density, so response is quick and setpoints are repeatable. Physically, it’s dimensioned to drop straight into the same quartz tube and R7s socket setup. The filament spacing and reflector geometry are tuned for the preform wall thickness window, so you get stable heating without hot spots.
Why it holds up on these machines
This lamp is built for direct compatibility across the Krones Contiform series—Contiform 3 and Contiform 3 Speed—and it also fits the broader Krones stretch blow molding family, including the Matrix platform and HyPET systems. One reference part can simplify your spares strategy across multiple lines. In practice, you get faster recovery to setpoint after a jam clears, more consistent bottle weight, and fewer lamp-related stops. Energy use stays aligned with the original design because the output curve follows the machine’s heating profile, not some off-spec generic emitter.
The details that keep it running
Installation is straightforward, but you have to confirm the exact lamp length, end-seal type, and connector orientation against your specific heating module and revision level. Check voltage and polarity at the terminal block, and keep the reflector clean—film buildup will throw off temperature distribution even with a good lamp. Expect about 5,000 hours under normal line loads. Higher duty cycles and frequent power cycling will shorten that, so keep the heaters at stable setpoints and plan replacements ahead of time.
