Introduction

Here’s the thing: when you’re working with tight spaces, you can’t just slap in any old heater. We built this under-desk heater around a 400V halogen quartz lamp for one simple reason—it packs a serious amount of heat into a small footprint. It’s the kind of solution you reach for when you need focused, fast-response heat for industrial equipment, but without the headache of redesigning the entire chassis.

Power, Voltage, and Dimensions

We went with a 400V rating because it lines up perfectly with standard plant power. That keeps the current draw manageable, which matters when you’re cramming everything into a confined space. The unit cranks out 2500W inside a 300mm tube. That’s a lot of watt density, so the heat comes on fast and settles in quickly. It’s predictable, reliable. But, and this is important, your machine’s thermal management needs to be ready to handle that heat and move it away from the immediate area.
