Technical Deep-Dive: Power, Voltage, and Dimensions
Let’s get real about what makes these tungsten halogen heater tubes tick. We built them to pack a serious punch—high heat, in a small package. A typical unit runs at 2500W on a 400V circuit. That high-voltage, high-wattage combo keeps the filament scorching hot, which is exactly what you need for that intense infrared output. The kind that gets you fast, pinpoint heating. And the 300mm length? It’s just right. Enough radiating surface to cover your target area, without forcing you to rework your whole machine.
Material and Design: Halogen Cycle and Connectors
Inside, you’ve got a quartz envelope, a tungsten filament, and a halogen gas fill. Here’s the magic: the halogen cycle actually redeposits evaporated tungsten back onto the filament. So the tube stays clear, and the filament lasts way longer—even at extreme temperatures. We also hooked these up with an R7s connector. It’s a simple, two-contact design that handles the current safely. And when it’s time to swap a burnt-out unit, you can do it in seconds. No tools. No hassle.
Application and Benefits
These tubes are the go-to for PET blowing, plastic thermoforming, and shrink-tunnel lines. Places where you need heat, right now, and temperature control you can count on. The design fires up fast and holds steady. But here’s the catch: that high heat density means your cooling system has to be up to the task. You’ve got to manage the ambient heat to keep the rest of your machine safe.
