On the blow molding line, the heating tunnel is where the rubber meets the road. If preform temperature starts to drift, you know what follows—uneven wall thickness, blown bottles, and scrap piling up. When the original SIPA SFR 16 infrared heater starts to lose its edge, you need a replacement that behaves like the OEM unit—same output, same response, and the same mounting footprint. What matters under the hood We build the SIPA SFR 16 infrared heater as a true 1:1 match to the SIPA SFR series, using short-wave quartz emitters for fast, controllable heating. It runs on the specified voltage and power, with R7s connectors and the same physical envelope, so it drops straight into the existing brackets and wiring. The infrared output is tuned to the preform’s PET absorption band, heating the surface quickly and keeping the temperature profile repeatable cycle after cycle. Why it behaves on the machine In stretch blow molding, the preform has to hit the right temperature band before it ever sees the mold. With this heater, you get faster stabilization after startup and a tighter temperature spread during long runs. That translates into fewer pinholes, better clarity, and less trim waste. Energy use stays in line because the emitter hits target output quickly and holds steady, avoiding the overshoot and cycling that burn kilowatts for no reason. The details that keep it honest This is a direct-fit replacement, but you still need to confirm the exact voltage and control type on your SIPA SFR machine, then set the heater offsets in the controller to match the original profile. Keep the reflector clean and aligned—even a small misalignment shifts the hot zone and drifts bottle quality. Expect shorter warm-up times than halogen, but plan for proper shielding and cooling to protect nearby components.
