Sidel IR Lamp Replacements: No Hassle, No Headaches

Getting the thermal profile just right in PET blowing is a pain. If your wall thickness isn’t uniform, you’ve got a problem. That’s why we build our infrared lamps to fit Sidel gear perfectly—whether you’re still running the old-school SBO systems or the newer Matrix lines. It’s all about the fit. Most people think wattage is the only thing that matters. It’s not. The physical footprint is where things usually go sideways. We make sure our lamps match the exact length and connector types of the Sidel originals. This means you just pop them in and go. No messing around with lamp holders, no rewiring the oven, and no stress. Because if a lamp is off by even a few millimeters? You’re putting pressure on that quartz tube. And that’s a one-way ticket to a premature burnout. The heat stuff We use short-wave IR tech so the heat actually gets into the PET preform quickly. Plus, we use high-purity quartz because these things take a beating with constant rapid cycling. The tungsten filaments are tuned specifically for SBO and Matrix power supplies. If you need fast cycle times, these high-wattage tubes give you the heat density to make it happen. Just a heads-up: if you’re putting higher wattage into an older SBO oven, keep an eye on your cooling blowers. You don’t want to overheat the machine frame, so watch those exhaust temps. Keeping things simple These are built for fast swaps during your scheduled downtime. We use connectors that can handle the heat without oxidizing or getting brittle. Here is a pro tip: when you’re doing a full plant overhaul, buy in bulk. If every oven cavity has the same spectral output, you won’t deal with those annoying “cold spots” in your preforms. When you mix and match different brands, the heat absorption changes. That leads to inconsistent bottle weights, and nobody wants that. Stick to one spec across the whole line. It just makes life easier.

Can I use PET lamps for PC preforms

On the blow molding line, preform material mix-ups aren’t theoretical—they hit you as scrap, uneven stretch, and downtime you didn’t plan for. The question that keeps coming up is whether PET lamps can run PC preforms on Sidel, Krones, SIPA, Husky, SACMI, or Nissei ASB machines. The short answer: sometimes, but only if the heating system is set up for PC’s thermal behavior and the lamp specs match the OEM tunnel design. What matters, technically In stretch blow molding, infrared heating is about spectrum and temperature control, not just wattage. PET preforms are usually heated with short-wave (quartz halogen) emitters tuned around 1.0–1.2 µm—they hit temperature fast with high peak power. PC preforms need a longer, more controlled profile because PC absorbs less in that band and responds differently to heat. Medium-wave or NIR emitters, typically 2.0–3.0 µm, give deeper penetration and more even through-heating, which helps avoid hot spots and surface degradation. Swap emitters and you have to match voltage, wattage, base type, and the physical envelope—length, diameter, and quartz tube profile. On many blow molders, the heating tunnel reflectors and zone spacing are designed around a specific emitter geometry. Change that geometry and you change the spot pattern, which can drive temperature non-uniformity. Why it can work (with limits) If you’re running PC preforms on a blow molder that was originally set up for PET, you can use PET-form lamps as a stopgap—but only if the machine’s heating zones can be re-tuned and the lamp’s output spectrum still delivers enough energy to hit PC processing temperature. In the field, we’ve seen lines hold stable preform temperature with PET lamps only after increasing dwell time and dialing zone power down to keep the surface from overheating. You only see a real payoff when you keep the lamp parameters inside the OEM’s specified envelope. Step outside it, and you’re back to uneven wall thickness, crystallinity issues, and more rejects. What to check before you try Before you drop a PET lamp into a PC preform job, confirm connector compatibility—R7s is common in many tunnels—and make sure the lamp length clears the reflector and terminal blocks without risking arcing. Also verify the power supply and thermocouple feedback are matched to the emitter type; mismatched control will cause overshoot. One hard constraint: PET lamps operating in a PC heating window can run hotter at the surface. That shortens service life and raises the risk of quartz devitrification if airflow and cooling aren’t tuned properly. Run a controlled trial, log zone temperatures, and be ready to switch back to the OEM-matched emitter for consistent, long-term output.

Industrial quartz infrared lamps for preforms

On the blow molding line, preform temperature is the tightrope. Too cold, and the bottle splits at the shoulder. Too hot, and you kill the PET molecular orientation—barrier performance goes with it. When the heating tunnel can’t hold setpoint, you don’t need a sales pitch. You need heat that repeats.

What actually matters under the hood

We build industrial quartz infrared lamps for preform heating in stretch blow molding. Short-wave output hits hard and fast, penetrating the PET wall quickly so the preform surface and core close the temperature gap within the tunnel dwell. We match OEM electrical and mechanical interfaces—R7s connectors, 240V/480V options, and exact quartz tube lengths and diameters. Power density is tuned to the heating zone profile: enough punch to recover fast after a jar change, yet stable enough to hold ±1°C control when the line settles in.

Wholesale infrared lamps for PET oven

On the blow molding floor, the heating tunnel is where the whole schedule lives or dies. If preforms come out uneven—neck too hot, shoulder still cool—you’re asking for thin spots, flash, or a stretch that doesn’t lock in strength. And when the lamps are underperforming, the oven tries to compensate by running hotter. You end up paying for the energy, but you’re not fixing the root issue. Infrared lamps in a PET oven aren’t just another consumable. They’re the calibrated heat source that makes repeatability, cycle time, and scrap numbers possible. We supply infrared lamps built as direct replacements for PET ovens on blow molding platforms—Sidel, Krones, SIPA, Husky, SACMI, and Nissei ASB. The idea is straightforward: match the OEM electrical and thermal parameters, and the machine gets back to the heating profile it was designed to run.
