Making Your Infrared Heaters Just… Work

We built our infrared lamps to be simple drop-in replacements. If you’re running a blow molding machine, there’s a 95% chance our gear will fit right in. We aren’t trying to force a “universal” fit on everyone; we just stuck to the electrical and physical standards that PET bottle production actually uses. The Power Stuff Most ovens need a lot of punch to get that heat density right. Because of that, we make tubes ranging from 230V to 400V. Take a 400V 2500W tube—it puts out a massive amount of thermal energy. That’s what you need to soften PET preforms quickly. Just double-check that your wiring and power supply can actually handle that load. And a heads-up: if your cooling system is a bit weak, the heat from these high-wattage tubes might trip your sensors. Quartz and Connections We use heavy-wall quartz glass infused with halogen. It’s a smart move because it lets the lamp run hotter without killing the filament. As for the fit? We use standard R7s and Sk15 connectors. That means you can just wire them up. No hacking apart your lamp holders or swapping out the whole socket assembly. Some of our tubes even have a special coating. It shifts the infrared spectrum so the heat actually sinks into the PET wall instead of just scorching the outside. Real Talk: On the Shop Floor At the end of the day, nobody wants downtime. When a lamp pops, you can’t spend three hours re-engineering your oven. Our lamps match the length and diameter of the big-brand OEM parts. You can swap a dead tube in a few minutes and get back to work. One last thing:**be careful with the glass.**Quartz is fragile. Always wear gloves. If you get skin oils on the tube, it creates a hot spot that’ll crack the glass the first time it heats up. Not a great way to start a shift.

Stop Overpaying for Your Krones Contiform IR Lamps

Let’s be honest: OEM parts are expensive. When you’re running Krones Contiform machines, those infrared lamps are essential, but the price tag on the brand-name replacements can really chew through your margins. You need the heat to be perfect, but you don’t need to pay a “brand tax” just to keep your line moving.

The trick to getting the heat right

Heating PET preforms is a bit of a balancing act. If the heat isn’t hitting the exact right spots, you’re in trouble. You end up with “cold spots,” which means your bottles come out with uneven walls or that annoying pearlescent look. Not a good look for the final product. We built our lamps to hit those same specific absorption bands that PET requires. The goal is simple: uniform heat from top to bottom. No guesswork, just a consistent glow that gets the plastic to the right temperature every single time.

Stop Fighting Your SIPA Oven

If you’ve ever run a SIPA rotary machine, you know the headache of uneven heating. One minute everything is fine, and the next, you’re staring at bottles with weird wall thicknesses or that annoying pearlescent haze. Most of the time, the culprit is a “close enough” lamp. Here’s the thing: “close enough” doesn’t work with infrared. When shops use lamps that almost match the specs, they’re playing a dangerous game with the physics of the machine. The problem with “near-matches” It all comes down to how the power flows. If the wattage on your replacement lamp is even slightly off, it changes the current draw. If a lamp runs a bit too cool, your first instinct is to crank up the oven temperature to compensate. That sounds like a quick fix, but it actually puts a massive amount of stress on your heating elements. You’re basically forcing the system to work harder than it was built for, which is a fast track to premature burnout. We build our lamps to hit the exact wattage and voltage of the original equipment. It keeps your PID loops stable and stops the guessing game. Plug and play We use high-purity quartz glass and a halogen cycle so the light output doesn’t just drop off after a few weeks. Depending on which generation of machine you’re running, we use standard R7s or SK15 connectors. It’s a simple drop-in. No rewiring, no tinkering, no frustration. Just a concentrated burst of shortwave radiation that hits the PET preform exactly where it needs to. The reality of the shop floor But let’s be honest—the lamp is only half the story. You can have the most perfectly spec’d tube in the world, but if your reflectors are oxidized or your cooling fans are choked with dust, it’s still going to overheat. It’s like trying to breathe through a straw. Keep the oven internals clean. If the heat can’t bounce off the reflectors and hit the preform, it just soaks into the machine frame. That’s wasted energy and a recipe for failure. At the end of the day, consistent IR output means you stop tossing rejects in the bin. You don’t have to spend an hour tuning the oven every time a bulb pops. Just swap the tube, check your voltage, and get back to making bottles.
