Stop Overpaying for Your Krones Contiform Lamps

Let’s be honest: OEM parts are expensive. If you’re running a Krones Contiform line, you know exactly what I mean. The costs add up fast, and it starts to feel like you’re paying a premium just for the brand name on the box. We decided to fix that. We make IR blowing lamps that do the exact same job as the factory ones—delivering that precise shortwave heat to your PET preforms—but without the massive markup. The nitty-gritty on power These aren’t your average lightbulbs. They’re built for high-voltage industrial environments. We’ve dialed in the wattage-to-length ratio so the heat hits exactly where it needs to. If you’re running a 400V system, you need filaments that can actually handle the load. We use heavy-duty tungsten because it stays stable. It doesn’t just flicker or burn out the moment things get intense. But a quick heads-up: high wattage means they ramp up fast. Just make sure your cooling blowers are actually doing their job. If your airflow drops, these lamps will cook the PET, and you’ll end up with those annoying burnt zones or that cloudy pearlescence in your bottles. Glass and connectors that actually last We use high-purity quartz glass. Why? Because it doesn’t soak up the IR energy itself. Instead, it pushes all that heat outward, straight into the preform. For the connectors, we stick with R7s or Sk15. They handle the “breathing” of thermal expansion much better than a soldered joint ever would. Plus, we offer coated versions. These act like a mirror, bouncing the heat back toward the center of the oven instead of letting it waste away against the machine walls. Getting them into your machine Swapping these in is easy. You wire them up exactly like the original parts. We’ve kept the tolerances on the diameter and length tight, so you won’t be fighting to get them into the lamp cages. No forcing, no jamming—they just fit. Now, look, these tubes take a beating in a 24/7 production cycle. That’s just the nature of the beast. While we build them to hold their output for thousands of hours, the filament will eventually age. That’s normal. But by switching to our versions, you’re cutting your maintenance costs way down without sacrificing the quality of your bottles.

Getting Your IR Lamps Right for Sidel SBO and Matrix Machines

If you’ve ever dealt with PET blow molding, you know that preheating is where the magic—or the nightmare—happens. You need that heat to be perfectly uniform. When you’re switching from the old-school SBO machines over to the newer Matrix series, the biggest headache is usually trying to keep the heat distribution consistent without having to rip apart your oven chassis. The trick is all in the footprint. We build our lamps to be a mirror image of the OEM Sidel specs. Why? Because if a lamp is off by even 5mm, or if the wattage is slightly wonky, you’re going to end up with cold spots in your preforms. It’s frustrating. We use short-wave IR emitters so the heat hits the PET wall fast. This keeps your cycle times low. Just a heads-up: if you decide to go with a higher wattage than what the machine was originally built for, keep a close eye on your cabling. You don’t want to fry your wiring looms. No rewiring. No drama. Nobody wants to spend their shift rewiring an oven. That’s why we stick to standard R7s and SK15 connectors. You just swap them out and get back to work. We also use doped quartz glass. It basically filters the energy so the heat goes into the plastic, not into the oven walls. It stops your reflectors from baking and wearing out prematurely. The real-world stuff These are true drop-in replacements. You pull the old tube, slide the new one in, lock the connectors, and you’re done. No drilling. No bending brackets. No swearing at the hardware. But here is the thing… a brand-new lamp can only do so much. If your reflectors are pitted or covered in oxidation, you’re never going to hit your target temperature. It’s like putting racing tires on a car with a broken engine. Do yourself a favor: give those reflectors a good clean before you swap the lamps. That’s the only way to actually get the full wattage you’re paying for.

Getting Your Sidel SBO and Matrix Lamps Right

If you’ve ever dealt with PET blow molding, you know the headache of preform deformation. It all comes down to heat. If your thermal profile is off, your bottles are off. That’s why we build shortwave infrared lamps specifically for Sidel systems—everything from the old-school SBO lines to the newer Matrix series. The fit has to be perfect. Here’s the thing: Sidel machines aren’t all built the same. The oven footprints vary, and that makes replacements tricky. We build our lamps to match the OEM specs exactly—both the physical size and the electrical load. Whether you’re running 230V or 400V, we match the wattage so your heat flux stays steady throughout the cycle. We use high-purity quartz glass because these things take a beating from constant thermal cycling. And we’re obsessive about the measurements. If a lamp is off by even a single millimeter, or the end-cap spacing is slightly skewed, you’re looking at a mechanical clash during install or a loose connection. Nobody wants that. We keep the tolerances tight so you can just slide them in and go. It’s more than just “plug and play” We use specialized coatings to shift the emission spectrum. Why? Because we want the heat to actually penetrate the PET wall, not just scorch the surface. To keep things moving fast on the floor, we stick with standard R7s and SK15 connectors. Now, a word of caution. High-wattage tubes are great for fast cycle times, but they put a lot of stress on your reflectors. Check your reflectors before you swap the tubes. If they’re pitted or oxidized, a brand new high-output lamp is just going to waste energy—or worse, overheat your housing. It’s a quick check that saves a lot of trouble later. Making life easier at the plant If you’re doing a full plant overhaul, buying in bulk is the way to go. It kills the downtime. The best part? We’ve made these compatible across the whole Sidel range. You don’t need a dozen different SKUs for a dozen different machines. You just plug them in, tweak your temperature controllers, and get back to work. No need to modify the oven frame or mess around with the hardware. It just works.
