On an aseptic PET line, uptime is the whole ballgame. When the heating tunnel on your Krones blow molder starts to drift, you see inconsistent preform stretch, pinholes, and the kind of microbial risk you can’t talk your way out of. The line stops. OEE tanks. You don’t need a “good enough” lamp. You need a heating radiator that matches the geometry, power profile, and control logic of your Krones PET aseptic blower, period. What matters under the hood We build the Krones PET aseptic blower heating radiator around short-wave infrared emitters tuned to the OEM’s heating window. Quartz envelope, filament geometry, reflector layout—everything is spec’d so the energy hits where the preform neck and body need it. No hot spots. No cold seams. It comes configured for the standard R7s connector, rated for 230V/460V service, and sized to drop straight into the existing heating tunnel footprint without rework. Output stays stable across the full blow cycle, so temperature control is repeatable from the first bottle to the last. Why it plays on a Krones aseptic blow molder On these machines, consistent heating is the line between clean fills and a pile of rejects. This radiator brings the heating curve back to spec, so stretch ratios stay where they should and wall thickness stays uniform. Fewer jams, fewer manual interventions, and more bottles per hour. Energy use drops because the emitter hits setpoint faster and holds it tighter. Lamp life stretches out, which cuts spare-part spend and keeps maintenance hours in check. The shop-floor details Installation is straightforward, but the heating tunnel optics have to line up with the preform path. Misalignment will show up as uneven heating, even with a good lamp. Before ordering, confirm your blower’s exact lamp length, wattage, and connector style. Also check the reflector—if it’s pitted, you’re throwing away output. Plan the replacement during a scheduled stop. That gives you time to calibrate temperature sensors and verify aseptic integrity parameters after the change.
