Infrared module for high speed coater

On a high-speed line, the coater’s heating tunnel is where the whole run hangs in the balance. If the short-wave infrared module starts to drift, preforms miss their temperature profile, and the blow molder starts spitting scrap. We built this IR module specifically for high-speed coaters to match OEM performance—without the OEM price—and it drops in with 1:1 parameter matching to Sidel, Krones, SIPA, Husky, and other mainstream machines. Here’s what matters under the hood. The emitter is a short-wave quartz halogen lamp, tuned for fast response and stable output in the heating tunnel. Rated 1.5 kW at 230 V (with 110 V/240 V options), it hits 100% power in 0.8 seconds and holds temperature within ±2% across the preform heating window. Lengths are exact—300 mm, 330 mm, 350 mm, and 400 mm—with an R7s base and standard connector orientation for a straight swap. Peak wavelength lands at 1.0–1.2 μm, chosen because PET preform walls absorb that range quickly and evenly. Why it plays nice on the line. You keep your cycle speed because the lamp spools up fast, and the coating process sees repeatable heat density. The payoff is fewer underheated preforms, less scrap, and fewer stops for lamp changes. Energy use drops too, since short-wave output heats the preform, not the frame around it. We’ve seen units run 5,000+ hours with under 5% output drop—solid for 24/7 operation. A few shop-floor pointers. Installation is straightforward, but don’t skip the reflector alignment. Even a 1–2° offset shifts the hot zone and can move the coat weight profile. Double-check that lamp length and base match your holder, and verify the voltage at the terminal. If you’re in a high-humidity washdown area, spec the IP54-rated sleeve to keep condensation and cleaning spray off the quartz tube.
