You know the feeling the second it happens. The heating tunnel starts underperforming, and suddenly you’re dealing with preforms that are cold on one side, crystallized on another. The blow molder spends its day chasing scrap instead of running rate. Then you lose even more time swapping in a non-OEM heater, and the downtime just piles up. We build PET preform heaters that drop in as a true OEM replacement, no compromises. The goal is simple: deliver repeatable heat so your stretch blow molding results stay consistent. What actually matters on the spec sheet We match the OEM 1:1 on the numbers that count. For Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB machines, that means hitting rated power (typically 1.5–3.0 kW per zone), voltage (230/400 V), lamp length, quartz tube OD, and the right connector—usually R7s, but also proprietary terminals where needed. The short-wave infrared halogen emitters respond fast, with peak output around 0.8–1.2 µm. Preforms hit 95–120°C in 2–4 seconds as they move through the tunnel. Reflectors are dimensioned to match the OEM focal lines, so the heat profile stays stable across the preform wall. Why it plays on the line The payoff shows up where it matters—on the blow molding line. Stable preform temperature cuts pinholes, stretch marks, and weight drift, so you hit target bottle weight with fewer rejects. Faster warm-up and consistent output mean you keep the same cycle time, but with less energy. In a lot of plants, that translates to 10–15% lower kWh, because emitter efficiency and reflector geometry are matched to the machine’s thermal window. Replacement is plug-and-play. No re-engineering the heating zone. The practical details you can’t skip Matching the OEM spec is half the job. The other half is your environment. Keep the heating tunnel clean. Dust and flakes on the quartz tube will kill output fast. Check voltage stability and make sure connectors are fully seated—loose contacts cause uneven heating and shorten lamp life. If you’re running 24/7, plan replacements around scheduled stops. Even fully matched emitters have a finite life.
