On the blow molder, the day is won or lost in preform heating. If the heating tunnel can’t hit and hold the right temperature profile, you’re staring down uneven wall thickness, blown bottles, and scrap piling up. On the SIPA SFR series, the SIPA SFR 10 infrared radiator is built to keep that tunnel stable, shift after shift. What matters under the hood The SFR 10 is a short-wave infrared emitter—quartz tube, halogen filament—tuned for fast response and tight thermal control in preform heating. It runs on the standard voltage the SFR is spec’d for, with power density calibrated to the typical preform wall thickness and cycle times you see in stretch blow molding. The R7s connector and footprint are 1:1 with the OEM layout, so you drop it in without rewiring or tweaking brackets. In practice, that means the heating tunnel recovers fast after a jam clear and repeats the same profile, bottle after bottle. Why it fits the SIPA SFR environment This radiator was designed for the SFR’s real-world conditions. The wavelength and power profile pair cleanly with PET preforms, so surface heat penetrates quickly without scorching. The payoff: fewer temperature swings, more consistent biaxial stretching, and fewer pinholes. Startup recovery is quicker, changeovers throw off less scrap, and output stays predictable. Energy use drops, too—the emitter heats on demand and cools fast, so you don’t carry the idle losses you get with older, slower heaters. The practical bits Installation is straightforward, but the heating window is tight. Double-check the voltage and phase match your SFR unit, and verify reflector alignment—misalignment throws off the profile and drives uneven heating. Keep the quartz tube clean and inspect the R7s contacts for oxidation; contamination and poor contact are the two usual suspects when life comes up short. Expect consistent output for 5,000+ hours under normal duty cycles, and plan replacements during scheduled maintenance so you don’t get blindsided by downtime.
