Introduction
We built this replacement lamp for the machines that never stop—specifically, the SACMI rotary blow molders and the Krones Contiform 3 Pro. On these workhorses, the preform heating window is tiny, and every minute of idle time is money down the drain. So this lamp has to fire up to full heat instantly, without fail, so your line keeps moving without a hitch.
Power, Voltage, and Size—Kept Simple
It’s a 400V, 2500W halogen unit, packed into a 300mm length. That tight combo is exactly why it heats so fast. You hit the switch, and it’s ready—no waiting around. And the 400V design is intentional. It matches the machine’s electrical setup, which means less current draw than lower-voltage options. That keeps the wiring harness and terminals cooler, even when the machine runs continuously. The 300mm length? It drops right in, covering the preform heating zone without any rework.
Material and Design—Built to Stay Calm Under Pressure
Inside, you’ve got a shortwave halogen element inside a coated quartz tube. The coating helps manage infrared output and keeps the envelope temperature steady, so heating stays consistent and nearby parts don’t get cooked. The shortwave spectrum focuses the energy where it matters most, so heat transfers efficiently into the preform. And the R7s connector brings a solid, high-temp-rated connection—mechanical and electrical—so it holds up to the thermal cycling on the blow molder without loosening or arcing. Wire it up, and you can count on repeatable contact.
Real-World Use and What It Feels Like
On a SACMI rotary blow molder or a Krones Contiform 3 Pro, this lamp is a true drop-in. The fast start-up slashes warm-up time, and the stable output keeps preform heating repeatable, shot after shot. Now, here’s the honest part: a 2500W, 400V lamp runs hot. That’s just the reality of the power density. So your machine’s cooling system needs to be in good shape to handle the ambient load. When the cooling is where it needs to be, the lamp keeps the process steady and helps you avoid unplanned downtime.
