On the blow molding line, heating drift is the quiet killer. One radiator that’s not pulling its weight throws preform temperature off, and suddenly you’re chasing rejects—thin walls, crystallization, inconsistent stretch. The Sidel Series 2 infrared radiator is built to stop that drift at the source by matching OEM heating performance, pin for pin. What matters, technically We engineer the Sidel Series 2 infrared radiator to hit the 1:1 parameters mainstream blow molders expect—Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. Typical units run 2300–2800 W, 230 V, with quartz tube lengths dialed in and standard R7s connectors so the lamp seats the same way in the heating tunnel. Short-wave infrared output gives you fast, surface-driven heating, and the filament geometry plus reflector alignment keep the beam pattern in the narrow band your preform neck and body need. The tolerances are tight enough that you can swap lamps without retuning the heating zones. Here’s why it works in stretch blow molding: cycle time is set by how fast the preform hits the right temperature profile. Get the wattage, voltage, and emitter length right, and the lamp delivers repeatable heat density across each zone. That means fewer temperature swings, less scrap, and more consistent bottle weight and clarity. Energy use stays in line because the lamp heats on demand and cools quickly, so you’re not wasting heat in the tunnel. And because the build matches OEM dimensions, installation is a straight replacement—no bracket fabrication, no rewiring. Matching specs is only half the story. The lamp needs a clean, reflective tunnel with good airflow; heavy dust or oxidized reflectors will force it to overwork and shorten its life. Also check voltage stability at the socket—line sag and loose contacts stress the filament early. Expect around 5,000 hours of service life under normal conditions, and keep spares on hand for planned changeouts. That way you’re not chasing heat mid-run.
