Running a SIPA SFR 9 rotary blower, you know the day is won or lost in the heating tunnel. If the preforms aren’t hitting temperature evenly, you’ll see PET crystallization, wall thickness swing, and rejects that chew up cycle time. We built this heater tube to match the SFR 9 geometry and timing so the stretch blow molding window stays stable. What actually matters under the hood It’s a short-wave quartz infrared emitter, tuned for how PET responds fast. It runs on the standard 240 V feed on the SFR 9, with an R7s connector that drops straight into the existing lamp holder—no rewiring, no custom brackets. Power density is matched to preform surface area and tunnel dwell, so the surface heats quickly without scorching while the interior comes up to temperature in time for the blow stage. The tube profile follows the SFR 9 heating zone curvature, so the focal pattern stays consistent across every preform. On a rotary table, dwell is tight and repeatability is everything. This tube restores the original OEM heating curve, which means faster stabilization after startup and less scrap when you change grades. You’ll see energy use drop because the tube hits setpoint fast and holds it without overshoot, and bottle weight and clarity stay more consistent. And replacement intervals are predictable, so you plan maintenance instead of chasing lamp failures. Here are a few shop-floor details that matter. Keep the lamp aligned to the reflector and the preform path; even a small offset changes the heat map and drives variability. The quartz tube is sensitive to thermal shock—let it cool before you clean or handle it. Make sure the voltage at the terminal block matches; a mismatch will shorten lamp life and drift temperature control. We supply the exact geometry and electrical match for the SIPA SFR 9 so you can swap it in and run.
