Replacement lamp for Krones S24

On the line, the Krones S24 keeps a steady pace, and the preform heating tunnel has to stay in step. When an emitter burns out, you get uneven stretch, off-spec bottles, and a mad scramble to get the line back in control. The right replacement lamp for the Krones S24 isn’t just a bulb—it’s a matched heating element that puts the thermal profile back where the blow molder expects it. What matters, technically We spec the S24 replacement as a short-wave infrared lamp built on a quartz tube, cut to OEM dimensions and fitted with an R7s connector so it drops straight in. Pick the 1200 W or 1500 W version to match the original power density, with 240 V or 400 V to match your supply. Peak wavelength is around 950 nm, tuned for fast, efficient absorption by PET preforms. Response is near-instant, so you regain tight control over heating time and temperature. The filament layout and reflector geometry are engineered to spread heat evenly across the tunnel width, keeping wall thickness consistent across the whole pack. Here’s why it works in stretch blow molding: the heating phase sets everything that comes after. These infrared lamps recreate the OEM thermal profile, so you can hold setpoints without chasing hot and cold spots. The payoff is fewer rejects, stable bottle weight, and consistent top load. Energy use drops, too—short-wave IR heats the preform directly, with less wasted heat in the tunnel air. We’ve seen units run 5,000+ hours with less than 5% output drop, which means fewer changeouts and less downtime. On a 24/7 line, that translates to higher uptime and maintenance windows you can actually plan around. Installation and watchouts Swapping one in is straightforward—power off, let it cool, swap the lamp, and confirm alignment in the reflector. Make sure you’re using the correct voltage version; mismatched voltage will shorten lamp life and throw the profile off. Keep the reflector clean and check the terminal block condition every time you change the lamp. These run hot, so let everything cool before servicing and respect the specified clearance to nearby components. If your S24 has been retrofitted or the heating zone modified, verify the power rating against the current setup so you don’t overshoot preform temperature.
