Under-Desk Heater: 400V Halogen Quartz Tube with R7s Connector
Let’s talk about getting warm. Right where you need it. This under-desk heater is built for one thing: giving you a tight, intense burst of heat exactly where you want it. No heating the whole room. Just you, your space, and that instant comfort. At its heart is a 300mm halogen quartz tube, running at 400V and cranking out 2500W. That’s a lot of power packed into a small footprint.
The power behind the warmth
Here’s the thing about the 400V input. It’s designed to plug straight into standard industrial power. So you skip the bulky transformer. And that 2500W output in just 300mm? That means serious watt density. The heat comes on fast. No waiting around. It’s direct resistance heating, so the moment you need warmth, it’s there.
What’s inside makes all the difference
Inside that quartz tube, the halogen element does the heavy lifting. It keeps the heat output steady over time and helps the filament stand up to the constant on-off cycling. The quartz tube itself? It handles the wild temperature swings without breaking a sweat. And it stays clear, so the infrared heat just keeps flowing, consistently. Then there’s the R7s connector. It’s a no-fuss, industrial-grade connection. It locks in tight, handles the high current, and makes swapping out the tube a simple job.
Heat that works for you
When you’re tucked under a desk, you want control. You want heat that goes where you point it. This setup focuses all that energy on a small area. Perfect for keeping sensitive components warm or stopping things from freezing right where you’re working. Just keep in mind, with that kind of concentrated power, you need to give it a little breathing room. Proper clearance and airflow keep everything running safely and smoothly.
