Krones Contiform 3 Speed Heater Lamp: The Replacement That Just Works
Let’s talk about the Krones Contiform 3 Speed heater lamp. It was built for one reason: to slip right into the tough heating zones of the Contiform blow-molding line and do the job without drama. We designed it to match the original’s heat behavior, because on the plant floor you can’t afford surprises. It’s a straight swap. No modifications. No messing around with brackets. You pull the old one, pop this in, and you’re back up.
Power and electrical: the real-world numbers
It runs on 400V, which is standard for industrial heaters. That power feeds the halogen element inside, giving you the heat density the preforms need. The tube is 300mm long, and it’s rated at 2500W. That size isn’t random—it matches the footprint of the Contiform 3 heating section so the heat lands exactly where it should, without straying outside the zone.
What’s inside: halogen core, quartz tube, R7s connection
Inside you’ve got a shortwave halogen element, sealed in a quartz tube. This combo responds fast, and it holds steady even when the machine cycles quickly. The quartz coating isn’t there by accident. It helps manage the intense heat and protects the filament so it doesn’t burn out early. Then there’s the R7s connector. It’s a hard-wired, industrial connection that locks the lamp in place and carries high current without getting loose or arcing—even when the machine is vibrating.
How it performs on the Contiform line
On the Contiform, this lamp handles the preform heating stage. The whole point is consistent temperature across the preform wall, so every bottle comes out the same. This unit delivers that. And because it’s truly drop-in, you wire it up and run. No re-engineering. No extra downtime.
One practical note
The 2500W output is serious, so the machine’s cooling needs to keep up. If the cooling is undersized, the lamp will run hotter than it should, and that shortens its life. Match the lamp to the machine spec, and you get dependable performance—plus a lower total cost over time.
