High-Power Heat for PET Blow Molding
We built this heater block to be a straight swap for Krones and Sidel machines—especially the Contiform line. The whole point? Give you OEM-level heating without the OEM price. This thing lives for the relentless pace of PET blow molding, where heat has to be fast, precise, and rock-solid. It runs on 400V and packs 2500W into a 300mm tube. That power density is tuned to match the original equipment’s thermal behavior, so your preform heating stays consistent—shot after shot.
Power and Fit: Built for the Real World
That 400V, 2500W setup isn’t random. It’s there to get the preforms hot fast, so you can keep up with high-speed cycles. And the 300mm length? It’s a direct drop-in. No messing with machine modifications. The heat lands exactly where it needs to, keeping the temperature spread across the preform stable. One thing to keep in mind: all that power in a tight tube means your cooling system needs to be in good shape. Heat can build up in the area, so give your cooling circuits a quick check before you install.
The Core: Halogen Heat, Focused
Inside, you’ve got shortwave halogen technology in a quartz tube. It throws out intense, focused infrared energy that gets into the PET efficiently—so you’re not wasting power. The tube has a reflective coating that pushes heat forward, straight onto the preform. That helps keep the internal parts cooler and keeps more energy where it matters. And the connectors are standard R7s—solid, common, and dependable. They give you a clean, low-resistance connection, which helps reduce hot spots and the kind of connector failures that can stall your line.
What This Means for You
For your Krones or Sidel line, this is a reliable, budget-friendly way to keep things running. It’s truly plug-and-play, so maintenance is quicker and simpler. You get the high heat density you need for consistent bottle quality, and the toughness to handle the factory floor day after day. The payoff is a steady thermal process, fewer surprise stops, and costs you can plan around.
