On a Contiform 2 line, you feel preform heating before anything else. The heating tunnel runs a little hot, a little cold, and suddenly you’re staring at axial splits, blown shoulders, and a pile of scrap you didn’t budget for. Halogen lamps are always a gamble—output drifts, reflectors lose focus, and downtime starts to climb. The Krones Contiform 2 IR radiator is built to put the original IR heating performance back under control, so the temperature profile stays repeatable shift after shift. We built the Contiform 2 IR radiator around short-wave infrared quartz emitters, tuned to the same wavelength and heating window the machine expects. Each emitter uses the R7s connector and drops into the same mounting footprint, so you’re swapping onto the existing brackets, not re-engineering the tunnel. Power is calibrated to the Contiform 2 heating tunnel load, and the output stays stable enough to hold preform surface temperature within tight tolerance. That gives you predictable stretch behavior in the blow molder, fewer rejects, and bottle weight that doesn’t wander all over the place. Out on the floor, that translates to less scrap and less rework. Startup stabilizes faster, and the heating zone snaps back quickly when you change formats. Energy use drops because the emitters hit setpoint fast and hold it without overshoot. In practice, lamp life holds up through long campaigns, with output staying steady over thousands of hours—less fade, fewer lamp swaps, and more uptime you can count on. Installation is clean, but alignment is the detail that matters. Set the emitter position and reflector gap to the OEM tolerance; if you’re off, you’ll see hot spots and uneven heating. Verify voltage and cooling airflow before the first heat, and keep the reflector surface clean during changeovers. If you’re running a Contiform 2, this radiator is the spec-matched way to get back to stable, repeatable PET heating.
