We built the Ergomodul 1 heater bulb replacement for one reason: to give you a heat source you can trust that drops right into most blow-molding machines—no overhaul, no drama. Here’s the thing. It’s a shortwave infrared halogen lamp, designed to run on 400V. That voltage isn’t a random choice. It lets us pack serious power into a compact 300mm tube. 2500W, concentrated in a small footprint. That’s how you get rapid heat response—enough to warm PET preforms in seconds. But with that kind of power density, your machine’s cooling and electrical systems need to be in good shape. If the cooling is undersized, the area around the lamp gets too hot, and the lifespan drops. At the core, we use a quartz envelope because it handles the shock of fast heating and cooling cycles without flinching. Inside, the halogen cycle keeps the filament stable and stops the blackening you see in standard lamps, so output stays consistent over thousands of hours. The connector is an R7s base—a standard, tough industrial connector that handles high current without wiggling loose. We chose it because it fits universally. It physically drops in where you need it to go. On the shop floor, that means less downtime. No rewiring custom brackets. No waiting weeks for proprietary parts. You just swap in a drop-in replacement. The shortwave output hits the PET material directly, heating it from the inside out. That cuts energy waste and shortens the time the preform spends under heat, which helps preserve the material. For maintenance teams, the universal fit means you can keep a few on the shelf and swap them out in minutes, not hours. So your line keeps moving.
