We built this 400V halogen infrared heater to be a straight-up, drop-in heat source for industrial enclosures and process areas. At its heart is a 300mm quartz tube pumping out 2500W—serious radiant power that shines when convection heating just can’t cut it. We went with 400V because it keeps the current lower on the supply side. That means smaller cables and more sensible contactor ratings—without sacrificing heat density. Power, voltage, and size—kept simple You get 2500W packed into just 300mm. It’s a tight footprint that lets you heat a specific zone without blowing up the whole system. And running on 400V means less amperage for the same power, so switchgear selection is easier and voltage drop stays under control on longer runs. The compact shape also makes it practical to retrofit into tight spaces where you’re already short on room. What’s inside: halogen, coating, and a solid connection The halogen element inside the quartz tube keeps the filament temperature steady, so the radiant output stays consistent over time. A reflective coating on the tube pushes more energy forward—so you get stronger delivered intensity and less wasted heat spilling out the sides. And the R7s connector? It’s an industrial standard for a reason. It locks in fast, stays secure, and handles repeated heating and cooling cycles without working itself loose. Built for real-world conditions In production areas, this heater throws out fast radiant warmth that cuts right through air gaps. It helps you hold setpoints near machinery and in drafty bays where the air never stops moving. With 400V wiring, a tough halogen core, and the R7s interface, it’s a straightforward upgrade you can drop right in. Just one heads-up: that high heat density means you’ll want enough airflow—or proper shielding—to keep nearby components and your team safe from the warmth.
