Introduction
We built this desktop heater for engineers who are tired of bulky gear. You need serious, concentrated heat in a small space? This is it. It’s a 2500W halogen heater, designed to run on 400V and built around a 300mm quartz tube. We made it for tight spots and benchtop setups where you need heat fast, clean, and on demand.
Technical Deep-Dive
Here’s the deal: at 2500W and 400V, this thing packs a lot of punch into a tiny footprint. The 300mm tube focuses all that energy right where you need it. The result? Your work surface heats up almost instantly, and you can hold a steady temperature without a fuss. Running at 400V also means less current draw than lower-voltage options, which keeps wiring simpler and helps you keep the whole machine design compact. Just keep one thing in mind—this output is aggressive. So plan your cooling ahead of time to manage the ambient heat.
Material & Design
Inside, the halogen element sits in a quartz tube, and it runs hot—but clean. The coating helps protect the filament from breaking down over time. Quartz is tough. It handles rapid heating and cooling without cracking, so you can switch this heater on and off again and again without losing performance. And the R7s connector? It’s a direct, solid link. Easy to wire, easy to swap out. It’s built to take a beating in industrial environments, and it stays steady even when things are vibrating.
Application & Benefits
Use this when you need heat, right now, in one specific spot. Preheating small parts. Drying coatings. Supporting benchtop thermal work. With 2500W, 400V, and that 300mm form factor, you get predictable heat distribution and results you can count on, every time. Installation is straightforward. The R7s makes it a drop-in replacement on compatible fixtures. Just remember to plan for enough airflow and shielding so nearby components stay safe from the heat.
