Technical Deep-Dive
Here’s the heart of it: we built this tiny electric heater to be a shortwave halogen infrared lamp. It throws a tight, focused blast of heat right where you need it—especially when space is tight. The whole thing hinges on a compact 300mm quartz tube, running at 2500W and 400V. That high voltage with a smaller wattage is the secret sauce. It lets us push a lot of current over short distances without needing bulky copper busbars. The result? A super small footprint that still delivers the rapid, intense heating you need.
Material & Design
The quartz envelope is built to handle sudden temperature swings. It keeps the heat output steady, even when you’re cycling the lamp on and off quickly. And the halogen fill gas? That’s what protects the filament. It stretches the lamp’s life and stops that annoying blackening that kills output over time. Then there’s the R7s connector—a straight, two-pin ceramic base. It’s a trusted industrial standard for a reason. You can swap it out fast, with no tools, right on the line. If your machine already uses R7s, this is a straight plug-and-play replacement.
Application & Benefits
This lamp was made for jobs like PET blowing and small-part thermoforming. You know, the ones where you need serious, localized heat but don’t have room to spare. The shortwave spectrum cuts right through polymers, speeding up your cycle time. Now, a 400V, 2500W tube packs a serious punch. That’s a lot of heat density in a 300mm package. But here’s the thing: your machine’s cooling system needs to be up to the task to handle the extra heat. That’s the trade-off for getting that kind of power in such a small space.
