We built this touch-screen heater around a serious piece of hardware: a 400V, 2500W halogen infrared lamp. It was designed for industrial control panels—the kind of tight spaces where you can’t afford to wait around for heat.
What makes it tick
Here’s the thing: it runs straight off 400V, the same voltage you’ll find on most industrial bus lines. That means no bulky step-down transformers cluttering up your cabinet. Just clean, simple wiring and more room to breathe. The lamp itself is compact—300mm long and just 10mm across. So you get heat where you need it, right where you need it, without warming the whole enclosure. And with 2500W on tap, it warms up fast. Seriously fast. But that power comes with a heads-up. You’ll want to plan for thermal management—good ventilation or solid heat sinking—to keep the touch screen electronics calm and stable.
Built to last
The tube is wrapped in quartz and filled with halogen gas. That combo keeps the filament clean, even at scorching temps, so you get steady output for the long haul. And the R7s connector? It’s a straight, two-pin setup that snaps in and locks down solid. No wrestling with threaded caps in a cramped panel. If you’ve used R7s heaters before, this drops right in like a replacement should.
Why it matters in the real world
This heater was made for one thing: keeping touch screens and control interfaces working smoothly in factory gear. Cold starts, condensation, thermal drift—all those little headaches that make touch screens act up? This cuts through them. The shortwave infrared heats the screen surface directly, so you feel the response immediately. It’s predictable. It’s focused. Just keep in mind—with that much power packed into a small space, you’ll want to get the mounting and cooling right. That way you avoid overshooting the glass and keeping nearby electronics comfortable.
