We make electric radiator heaters for industrial work—the kind of places where you need heat, fast, and right where you need it, without taking up a ton of space. These aren’t your typical space heaters. They’re built as real process tools, designed to pack a serious punch in a small footprint—perfect for jobs like plastic processing and machine tooling. Here’s the thing about how they’re built. Most of these heaters run on 400V at 2500W, and that’s intentional. High voltage means lower current for the same wattage, so you can run heavier loads without having to bulk up your cables or contactors. And with a 300mm tube, you’re concentrating all that energy into a tight zone. That’s how you get high watt-density heat exactly where you want it. It’s the kind of setup that gets you rapid temperature rise, which is great. But it also means your machine’s cooling and thermal management need to be just as thoughtfully designed. Now, let’s talk about what’s inside. The heart of it is a halogen-filled quartz tube. The halogen chemistry keeps the element stable even at extreme temperatures, and it helps the output stay consistent over time by preventing that blackening effect. The glass also has a reflective coating. It focuses the infrared energy forward, so you get more effective heat delivery—and it protects nearby parts from getting blasted. Then there’s the R7s base. It’s a bi-pin connector built to handle high-temperature terminals, and it makes mounting secure and straightforward. It’s a direct drop-in fit, so when a tube finally gives up, you can swap it out without reworking the whole assembly. Out in the real world, this setup is a workhorse for jobs like PET blowing, thermoforming, and localized hot-runner heating. You get fast heat-up, focused infrared output, and a compact footprint. That combination keeps your process cycles tight and keeps the heat right where the work is happening. Just be ready for it. The output is serious, and the area around the tube gets hot. Plan for proper airflow and insulation—you’ll be glad you did.
