On the plant floor, an EvoBLOW heating tunnel doesn’t have time to wait for a lamp to come up to temperature. When an emitter dies, the line slows, preforms come up underheated, and you’re suddenly chasing rejects. We built the Sidel EvoBLOW heater lamp bulb spare to replace the OEM unit without guesswork. What matters, technically It’s a short-wave infrared halogen emitter, tuned for PET preform heating. The quartz envelope gives you rapid response and stable output across the heating tunnel’s duty cycle. We match the OEM wattage and voltage, so the power profile stays inside the machine’s control window. The R7s base and dimensions drop straight into existing sockets and reflectors, keeping the beam geometry intact. In practice, that means repeatable preform skin temperature and consistent stretch behavior in stretch blow molding. Why it holds up on an EvoBLOW line EvoBLOW lines live and die on timing and heat balance. Swap in a non-matched lamp, and heat density shifts—then the control system starts chasing setpoints. Our bulb keeps the heating curve flat, so you hold cycle time and cut scrap. Energy use stays in line because the emitter draws the same profile the machine expects. And replacements stay reasonable because we spec materials for the tunnel environment: heavy thermal cycling, voltage spikes, and constant on/off cycles. A few shop-floor details Installation is plug-and-play, but treat the quartz with respect. Fingerprints and oils create hot spots that shorten life. Check the reflector condition too. Pitting and oxidation scatter IR, and they can make even the right lamp feel weak. Expect peak performance up to 5,000 hours, depending on line voltage stability and how often the lamp switches on and off. If your tunnel runs at the upper temperature limit, keep spares in batches so you don’t get caught out by unplanned downtime.
