Stop Fighting With Your IR Lamps

Let’s be honest: most PET blow molding lines are a bit of a Frankenstein’s monster. You’ve got some gear from ten years ago mixed in with the new stuff. So, when a lamp finally burns out, the last thing you want is a “replacement” that forces you to rewire the entire oven. That’s why we build our IR lamps to just work. We’ve focused on the stuff that actually matters—electrical fit, size, and heat output—so they slide into about 95% of the machines you’ll find on a shop floor. Getting the heat right We offer everything from the standard 220V to high-output 400V tubes. Now, a 400V 2500W tube is a beast. It puts out massive heat, which means your cycle times drop and your output goes up. Just a heads-up, though: if you go that route, double-check your cooling system. If your oven can’t handle that extra ambient heat, you might end up warping your reflectors. Not a fun way to spend a Tuesday. The nitty-gritty: Glass and Plugs We use high-purity quartz because it handles thermal shock without cracking. We also stick to the plugs you already know, like R7s and Sk15. No weird custom adapters, no “making it fit.” Some of our tubes even have a special coating. Instead of just scorching the outside of the PET preform, this coating pushes the heat deeper into the wall. You get a much more even melt. Less time tinkering, more time running Replacing a lamp shouldn’t be a project that takes an hour of troubleshooting. We manufacture these to tight tolerances so they actually slide into the clips. No forcing, no bending. Plus, we keep these common specs in stock. That means no more waiting weeks for a shipment while your line sits idle. You get a lamp that fits the socket, matches your wattage, and hits the right temperature. No need to spend half your shift tweaking PLC settings just to get back to baseline.

Stop Replacing Your SIG Blomax Lamps Every Other Week

If you’re running a SIG Blomax line and you feel like you’re spending half your shift swapping out dead tubes, you aren’t alone. It’s frustrating. Usually, it comes down to two things: thermal stress and vibration. Most standard IR lamps just aren’t built for the chaos of a high-speed production floor. They can’t handle the constant shaking and the rapid heating cycles, so they just give up. We decided to fix that by beefing up the structural side of things. The heat problem To get that perfect wall thickness in a PET bottle, you need a ton of heat, and you need it fast. That means cramming high wattage into a small quartz envelope. When you push that much current through a thin filament, things get intense. If the quartz isn’t tough enough to handle those temperature swings, it stresses out and cracks. Simple as that. To stop the bleeding, we use heavy-wall quartz. It’s built to take the heat without breaking a sweat. It’s all in the seal A lot of people talk about “drop-in replacements,” but those only work if the fit is spot on. Here’s the real secret: most lamps die because the seal at the end fails. Once that seal goes, oxygen leaks in, hits the tungsten filament, and burns it out instantly. We’ve reinforced the ends of our lamps to make sure that vacuum seal actually stays put. It means the lamp can take a beating and keep on glowing. A quick heads-up Now, there’s a small trade-off. Because the quartz is thicker and tougher, it changes how the IR light passes through just a tiny bit. You might notice a slight difference compared to those ultra-thin glass tubes. You’ll probably need to tweak your oven temps by a few degrees to get your preform profile exactly where you want it. It takes two minutes, and it’s worth it. If you’re running multiple lines, it makes sense to grab these in bulk. It kills the downtime and saves your team from the endless cycle of replacing dead bulbs. Just wire them in, dial in your heat zones, and get back to actually producing bottles.

Krones Pet Aseptic blower heating tube

On an aseptic line, the heating tunnel is one of those pieces that gets taken for granted—until it starts drifting. Preform temperature variance shows up fast as uneven wall thickness, then as scrap and micro-leakers. When the original Krones heating tube is long past its prime, you don’t need a pitch. You need heat that repeats, cycles that stay stable, and uptime you can count on.
