350mm 2500W Infrared Halogen Heater: The Heartbeat of Your PET Blowing Machine

We built this 350mm, 2500W infrared halogen heater to be the direct-fit powerhouse your PET blowing machine is missing. It’s designed to melt preforms fast and do it again and again, fitting right into the standard heating zone like it was always meant to be there.

Power, Voltage, and Size—Why It Matters

Here’s the thing about that 2500W rating packed into a 350mm length: it’s all about concentrated heat. That power focuses right where the preform needs it—neck and body—so the material hits processing temperature in a flash. High wattage means short cycle times, sure. But it also means you need a steady electrical feed. That’s why we set this heater up for high-voltage operation, usually 400V. This keeps the current lower than you’d get with a 230V option, which means less voltage drop and less strain on your terminals and connectors. And that 350mm length? It’s not random. It’s chosen to drop straight into standard blow-molder heater blocks. No reworking the machine. No custom fabrication. Just swap it in and go.

Built to Last: Halogen, Quartz, and Smart Details

Inside, you’ve got a halogen-filled quartz envelope. The halogen gas lets the filament run hotter without blackening, so the heat output stays consistent over time. Quartz is great at transmitting shortwave infrared, which punches through the PET quickly, heating from the surface inward. We added a reflective coating on the outside to push more energy forward. Less wasted heat to the rear means better temperature uniformity across the heating zone. And the connector—an R7s or Sk15, depending on the variant—is a bi-pin design built for high heat. It gives you a solid, secure fit every time. No loose contacts. No alignment struggles. Just swap the lamp and get back to work.

Real-World PET Blowing Performance

On the floor, your PET blowing heater needs to hit temperature fast, hold steady, and handle rapid cycling without breaking a sweat. This lamp delivers the watt density needed for that quick melt, while the high-voltage design keeps the current load on your machine’s wiring manageable. That reflector coating helps keep the heating zone consistent, which cuts down on thin spots and stress marks. But let’s be real—2500W puts out serious heat. Your blow-molder’s cooling and airflow need to be up to the task. If they aren’t, heat buildup can shorten the life of components. For the engineers out there, this setup strikes a practical balance: serious output, rock-solid connections, and a size that fits the standard heater slots in PET blowing machines.
