On a blow molding line, the heating tunnel is where the rubber meets the road. Every minute of downtime, every off-spec bottle, usually traces back to temperature control. If you’re running a Sidel SBO 16 Series 1, the infrared heating tube has to behave like the original. Otherwise the preform profile drifts, and the machine ends up fighting itself. What matters under the hood We build the Sidel SBO 16 Series 1 heating tube as a direct-fit replacement, right down to the wattage density, dimensional reach, and mounting. Short-wave infrared gives you fast response, so the tunnel recovers quickly after a jam clears and you restart without a long warm-up drift. The quartz envelope and halogen filament are chosen to hold stable output across the tube life, and the terminations match the machine’s connector interface for a secure, repeatable install. In stretch blow molding, repeatability is the scoreboard. Tighter control of preform heating keeps wall distribution consistent and cuts rejects. The fast response also helps keep cycle times steady, because the tunnel gets back to setpoint fast after interruptions. In practice, that means fewer heating-related stops, less scrap, and lower energy per bottle. Installation is straightforward, but the heating tunnel is a harsh environment. Keep the reflector clean and double-check alignment so the heat profile stays centered on the preform path. Match voltage and wattage to the original spec; stray outside the rated range and you’ll shorten tube life and throw off the heating curve. For full compatibility, use the correct connector type and confirm your SBO 16 Series 1 firmware and sensor setup are calibrated to the OEM settings.
