The 235V 1000W Halogen Infrared Lamp: The Secret Weapon for Pre-Heating PET Preforms

We built this 235V 1000W halogen infrared lamp for one specific job: getting PET preforms perfectly hot before they get blown. The whole point? To pack a ton of power into a small space, heating things up fast—without forcing you to overhaul your entire system.

Power, Voltage, and the Right Kind of Punch

Here’s the thing about that 1000W rating on a 235V supply. It’s a sweet spot. We wanted serious heat, but we also needed to keep the current draw reasonable for the control gear. High power density means you can heat a preform in a flash. That cuts down cycle time. And it’s built for the real world, where the lamp gets switched on and off over and over again. But with that kind of concentrated heat, you’ve got to plan for it. Make sure you have enough airflow and heat shielding around the lamp. Otherwise, you risk cooking the components nearby.

The Good Stuff Inside: Halogen, Quartz, and a Solid Base

The halogen chemistry is what keeps the filament stable, even at scorching temperatures. That means you get consistent infrared output, and the lamp lasts longer. The quartz envelope is key, too. It lets shortwave infrared pass through efficiently, hitting the preform wall directly for even, uniform heating. And we went with a tough R7s base for a reason. It makes a rock-solid electrical connection and won’t loosen when things get hot. Best part? It’s a straight swap for what you already have. You can replace the lamp without having to re-engineer the reflector assembly.

Why It Works for PET Pre-Heating

When you’re pre-heating PET preforms, you need control you can count on. This lamp delivers repeatable temperature control every single time. The shortwave infrared gets right to the surface of the preform, and the halogen system responds instantly to PID control. The payoff? Tighter temperature bands, fewer rejects, and steady, reliable throughput. Its compact size fits perfectly into tight reflector cavities, and that high power density means you might need fewer lamps per zone. Just remember: you can count on predictable output, but you still need to plan for proper cooling to handle that intense heat load.
