When your Contiform 3 is pushing max cycles, the heating tunnel doesn’t forgive much. Preform temperature drift of just a couple degrees shows up fast—wall thickness that wanders, bottles that blow, and scrap piling up. We built the Krones Contiform 3 Speed lamp as a straight swap, 1:1 on parameters, so you keep the same thermal response, the same control, and the same uptime. What it comes down to, technically It’s a short-wave infrared halogen emitter, specced to OEM tolerances for the Contiform 3 heating section. Each lamp runs 2400 W on a 240 V supply, delivering the same heat density and ramp rate as the original. Quartz tube length and arc geometry match the reflector layout, so the preform heating profile stays consistent across all zones. And with the R7s connector and terminal orientation identical, the retrofit is straightforward on the machine. On a blow molding line, consistency is the only scoreboard that matters. This lamp holds stable output for 5,000+ hours with under 5% energy drop, which helps keep preform surface temperature inside the narrow window high-speed stretching demands. That means fewer rejects from uneven stretch, lower scrap, and changeovers that behave themselves. Energy use is down about 10% compared with non-matched aftermarket alternatives, because the emitter is tuned to the Contiform 3 reflector system, not a generic fit. Installation is plug-and-play on the R7s base, but you still need to verify lamp orientation and clearance inside the heating tunnel. If the reflectors are dirty or oxidized, the heating profile drifts—clean and inspect them while you’re in there. The lamp runs hot, too. Let it cool before handling, and confirm your cooling airflow matches the original machine spec to protect quartz life.
