Introduction
We built these halogen shortwave lamps for one place only: the tough, demanding environment of an industrial drying house. These aren’t your run-of-the-mill heaters. They’re precision tools, designed to blast concentrated heat exactly where you need it, right when you need it. Think of them as the specialist for high-intensity, repeatable drying on the production line.
What makes them tick
Here’s the secret: raw power in a small package. Each unit hits 2500W and runs on 400V. That voltage setup is key—it lets us pack a lot of heat into a compact space without tripping the system. More heat per square inch, without the bulk. The lamps are 300mm long, a size we chose on purpose. It gives you a focused heating zone without needing a giant housing or oversized reflectors. And the physics are beautifully straightforward. Shortwave radiation cuts right through moisture, heating the product from the inside out. That means cycle times plummet compared to old-school convection.
Built to last
We start with a quartz tube because it can handle sudden, brutal temperature swings without cracking. Inside, the filament is coated to keep output stable and stretch the lamp’s life. The halogen cycle does its thing, keeping the tungsten clean. So the lamp holds its brightness and heat output steady, hour after hour, for thousands of hours. Then we fit it with an R7s connector. It’s the industry standard for this kind of high-intensity work. That bi-pin design gives you a solid, low-resistance connection that can handle the heavy current without arcing or getting dangerously hot.
Why it works on the line
In a drying house, you can’t afford to wait around. These halogen lamps hit full temperature in seconds. No warm-up delay. Just instant, focused heat. That shortwave energy targets water molecules directly. Perfect for jobs like drying PET blowing preforms, where surface-only drying can ruin the finish. The 300mm length gives you a tight, controllable heat pattern, and the 400V/2500W combo delivers the density you need for high-throughput lines. Now, there is one thing to keep in mind. This level of output means you need proper cooling and ventilation. When you push heat this hard, managing the ambient temperature protects the housing and electronics. And the best part? It’s a straight swap for standard R7s halogen systems. Installation is simple.
The bottom line
These lamps are for engineers who need heat they can count on—fast, repeatable, and right on target. Shortwave halogen tech, 400V power, and the R7s interface come together to give you a solution that just works.
