Stop the Burn-out Cycle on Your SIG Blomax Lines
If you’re constantly replacing tubes on your SIG Blomax line, you know exactly how frustrating it is. It feels like as soon as you get the line humming, something pops. Usually, it comes down to two things: structural stress or thermal spikes. When you’re pushing 2500W through those IR radiators, the heat is intense. If the lamp can’t handle the constant vibration of the machine or the quick power cycles, it’s going to fail. Period. We got tired of seeing that happen, so we built our Sidel-compatible radiators with actual reinforcements to break that cycle. Dealing with 2500W of Heat Think about what’s happening inside that lamp. You’re forcing a massive amount of energy into a PET preform in a split second. To do that without the lamp giving up, you need a very specific tungsten filament and high-purity quartz. We spec our tubes to handle those annoying voltage swings you get on industrial grids. They’re drop-in replacements that fit the original footprint, but they don’t “sag” like the cheaper stuff you’ll find elsewhere. Where we beefed things up We spent a lot of time looking at the seal and the quartz thickness. Most standard tubes fail right at the pinch seal because the machine just shakes them to death. Our version uses a hardened seal and a special coating. That coating does something clever: it reflects heat back toward the product instead of letting it soak into the lamp housing. It keeps the lamp cooler and the product hotter. Getting them installed These are easy. Just wire them into your existing connectors and they’ll slide right into the Sidel racking. One heads-up, though. Because these are more rigid and have that reflective coating, the heat profile is a bit different than a worn-out OEM lamp. You’ll probably want to spend a few cycles recalibrating your oven zones to get the preform temperature exactly where you want it. And a quick tip: check your cooling fans. If they’re clogged with dust, no amount of reinforcement will stop a lamp from overheating. Keep the air moving, and these things will last.
