On the line, the heating tunnel is where the pressure hits. Preform temperature starts to drift, and you’re suddenly chasing marginal bottles—thin spots, stress cracks, top load that’s all over the place. On a SIPA SFL 2/2 linear blower, that lamp isn’t just heat. It’s the control point that keeps the preform in the tight thermal window the blow molder was built around. We designed the SFL 2/2 linear blower lamp as a direct-fit infrared emitter, built to match the OEM thermal profile and the mechanical footprint. It runs at the specified voltage and power, with an R7s connector and the exact length and mounting geometry the SFL 2/2 heating section needs. The quartz envelope and halogen/NIR output give you fast response and repeatable performance, so you hit setpoint quickly after a restart and keep things stable shift after shift. In practice, that means less time tweaking zones and fewer rejects tied to temperature. You earn uptime the old-fashioned way—by cutting unplanned stops. This lamp is spec’d to hold consistent output over long runs, and field experience shows many units staying in service past 5,000 hours with minimal drop-off. That means fewer changeouts, fewer spares sitting in the stockroom, and more consistent bottle wall distribution. Energy stays in line because the emitter matches the machine’s thermal load—no overdriving zones to make up for a mismatched lamp. Installation on the SFL 2/2 is straightforward, but alignment matters. The lamp has to sit square in the reflector and make clean contact at the R7s terminals; if it’s off, you’ll get uneven heating and you’ll shorten lamp life. And keep the heating tunnel clean—dust and film on the quartz kill output faster than most crews expect. Run the lamp at the machine’s rated settings, and you get repeatable preform heating, stable cycles, and fewer heating-related alarms.

On a blow molder that’s actually running, heating drift is what kills your consistency. You see it immediately when a lamp starts underperforming in the Contiform 2 heating tunnel—preform thickness starts jumping around, biaxial stretch falls off, and the scrap pile grows. We built the Krones Contiform 2 heating lamp as a direct replacement for the OEM, point for point, so your preform heating profile stays stable, shift after shift. What matters under the hood We match the Contiform 2 original heating performance with a short-wave infrared halogen emitter built on a quartz tube. The specs are 1:1 to the OEM: 2400 W at 230 V, 1850 mm active length, and an R7s connector so it drops straight into the heating tunnel reflector assembly. Filament geometry and reflector alignment give you the same spectral density and spot pattern, which means the same heat-up rate without re-tuning the oven zones. The lamp holds stable output for 5,000+ hours, with under 5% decay, and it starts instantly—no warm-up lag. Here’s why it works in stretch blow molding. Preform temperature has to land in a tight window before the blow station. This lamp keeps that window tight across the full bottle mix—from 28 mm to 120 mm necks—so you cut scrap and keep unplanned stoppages down. Energy draw stays close to the OEM baseline, and because the dimensions are 1:1, you keep the same lamp alignment and airflow path. No new hot spots, no cold zones. You get repeatable quality, and you’re not swapping lamps every other week. A few shop-floor notes. Installation is plug-and-play on the R7s socket, but the reflector window needs to be clean and untouched. Any hazing scatters energy and throws the heating off. Also, double-check voltage at the lamp terminals—mis-wired 230 V circuits will shorten lamp life fast. Pair the lamp with a calibrated pyrometer for zone control. Without real measurement, even a matched lamp can drift as ambient conditions and line speed change.
