On the line, a Husky HyPET blow molder doesn’t forgive uneven preform heating. You can spot it instantly—wall thickness that wanders, bottles that blow out, and the whole line throttling back just to chase temperature stability. The Husky HyPET heating lamp SK15 is a direct-fit infrared upgrade built to keep that heating tunnel honest, cycle after cycle. Here’s what’s actually under the hood. The SK15 is a short-wave infrared emitter using a quartz tube and an R7s connector, dimensioned to match the OEM geometry and mounting. It runs within the same voltage and power window as the original halogen lamp, so your control logic and setpoints stay put. Preform heating stays repeatable because the spectral output and focal pattern are matched to the preform wall—tight temperature spread, no hot spots. And in practice? The SK15 comes back to thermal stability faster after a restart and holds steady during high-speed stretch blow molding. That means fewer rejects and more uptime. We’ve logged energy use coming down by about 20% compared with standard halogen, and lamp life stretching to 5,000+ hours with less than 5% output drift. Put it in once, then stop stockpiling spares. A couple of shop-floor notes. Install it with the correct orientation and check the reflector—misalignment will throw the heat profile off. The SK15 is a direct replacement for Husky HyPET systems, but confirm your machine revision and connector type before ordering. If the heating zone PID has drifted with age, expect a quick recalibration; once you set it, the profile stays consistent.
