On a PET line, the heating tunnel is where you really earn your keep. If the Sidel blow molder oven lamp can’t hold the preform temperature profile, you’re staring down thin walls, crystallization, or short shots—and the whole line pays for it. We built this infrared emitter to drop in for the Sidel oven lamp without guesswork, so the heat profile stays true to the machine’s original intent. What matters under the hood This is a quartz halogen infrared lamp, engineered for the Sidel heating tunnel: power matched tightly, spectral output stable, and thermal behavior repeatable. The filament geometry and reflector layout are tuned so the heat field lands predictably, and every preform in the row sees consistent radiant energy. You get a clean, repeatable temperature rise—no wild swings—because the lamp’s output curve plays cleanly with the tunnel’s zone logic. We size the wattage to the OEM intent, so you’re not chasing the heating curve by overdriving zones. Here’s the thing: in stretch blow molding, preform heating is the gatekeeper. With this lamp, you stabilize heating penetration and cut the drift that drives weight variance and blow-up failures. Fewer rejects, fewer micro-adjustments, more uptime. Energy use drops because the lamp heats on demand with minimal warm-up, and lamp life is built for long-run reliability—units running 5,000+ hours with minimal output loss. Installation and housekeeping Installation is straightforward, but the oven is a harsh environment. Verify the connector type (often R7s), confirm voltage and socket condition, and make sure the reflector and quartz tube are seated without stress. Temperature swings, cooling airflow, and frequent door openings will shorten service life. Keep the tunnel clean and maintain airflow as specified. Match the lamp to the OEM’s power and thermal layout—don’t mix lamp types across zones.
