Run a Krones Ergomodul 2 and you already know the feeling: the whole heating cell is walking a tightrope. One lamp goes south, the tunnel profile drifts, and you watch output drop before you can even call maintenance. Then you get to chase down a replacement that fits—without forcing you to re-tune the entire line.
What matters under the hood
We built the Ergomodul 2 heater lamp as a direct-fit infrared emitter, spec’d to the machine: quartz envelope, halogen filament, and an R7s connector. It hits the voltage and wattage the heating tunnel wants, so the preform heating curve stays where it should. The filament geometry and reflector alignment are set to keep heat density consistent across the preform wall—exactly what you need for repeatable stretch and blow performance.
Why this one stays in the machine
With this lamp installed, the Ergomodul 2 keeps running its intended cycle instead of fighting temperature swings. Alarms quiet down, you do fewer manual interventions, and you stop paying for scrap from off-heat. Energy stays near baseline because the emitter matches the machine’s thermal design, and downtime shrinks because the swap is clean—drop it into the holder, no custom brackets, no rewiring.
The shop-floor details
The bulb is engineered for the Ergomodul 2, but it still needs clean contacts, proper alignment, and the right voltage. Handle it by the base, not the quartz tube, and check the holder during install. Oxidized terminals and bent contacts will kill it early—even with a good lamp.
