Getting to Know the Halogen Infrared Heater

Here’s the deal: we built this halogen infrared heater to be a compact powerhouse. It’s all about delivering intense heat exactly where you need it, no fuss, no wasted energy. Think of it as a focused spotlight—but for heat. We packed 2500W of power into a 300mm quartz tube, running on 400V. It’s shortwave, it’s intense, and it’s designed for one thing: serious heat in a small space. The response is almost instant. You flip it on, and it’s ready to go. No waiting around.

Why the 400V setup?

It comes down to smart design. Running at 400V keeps the current lower while still hitting that 2500W mark. And lower current? That means you can use thinner wiring, cheaper components, and you won’t have to worry about voltage dropping off over distance. It makes the whole setup easier to wire and install. And the 300mm length? That’s just the sweet spot. Enough radiant surface to cover the zone you need, without making you redesign your whole machine around it.

What’s going on inside?

The quartz tube can take a beating—it handles the shock of heating up and cooling down, over and over, without cracking. Inside, the halogen cycle is doing its thing, pulling evaporated tungsten back onto the filament. That’s what keeps the output steady and extends the heater’s life. We also tweaked the inner coating to shift the output toward shortwave infrared. Why? Because that’s the wavelength that industrial materials—like plastics—soak up best. It’s all about making sure the heat goes right where you want it, and not wasted on heating the air.

Built to survive the shop floor

Everything about this heater is made for real-world use. The R7s connector is a proven, rock-solid design. It locks the tube in place, handles the 400V load without blinking, and stays tight even when things are vibrating and heating up. And if you’re replacing an old unit? It’s a straight swap. Just pop it in. No messing around. That means less downtime when you need to do maintenance.

Where this thing really shines

This heater is your go-to for jobs that need fast, pinpointed heat. Think PET blowing, plastic welding, curing—any task where the material needs to grab energy quickly. The shortwave heat gets right into the surface without scorching the air around it. But here’s the thing: that kind of concentrated power needs respect. A 2500W output packed into a 300mm tube means you’ve got to plan for the heat. Your machine needs proper cooling and shielding to protect nearby parts. When you set it up right—match the electrical supply, get the mounting sorted, and manage the cooling—you get heating that’s fast, reliable, and consistent. Day after day.
