Introduction
We built this shortwave infrared halogen lamp for one reason: to dry decorative glass ink the right way. You need to strip out moisture fast—without wrecking the color. Traditional hot air? It’s slow and wasteful. This lamp goes straight after the water, not the pigment. The result? The ink stays true, and the job gets done.
Power, Voltage, and Size: The Practical Details
This thing runs on 400V, not the usual 230V, because we fit 2500W of heat into a compact 300mm tube. That higher voltage keeps the current manageable, so you don’t need to overhaul your wiring or hunt down oversized contacts just to handle the load. And the short 300mm length? It gives you a tight thermal footprint. Easy to slot into your existing line without tearing apart the whole oven area.
Heat with Control
This is high heat density, plain and simple. It ramps up fast and responds quickly, which is great. But it also means your machine’s cooling and thermal management have to be up to the task. If you run it at full power nonstop, ambient heat can build up. So pair it with a system that can shed that heat cleanly.
What’s Inside, and Why It Matters
Inside, the halogen element sits in a quartz envelope. Quartz was chosen because it handles sudden temperature swings well and lets strong infrared through. The shortwave output peaks where water absorbs energy efficiently. That’s how you get quick evaporation while keeping the glass surface under control. A selective coating on the quartz helps focus the energy toward the work, so less heat goes to waste and nearby parts stay protected from stray radiant heat. Installation is straightforward, too. The R7s connector is an industry-proven interface that lets you wire the lamp quickly—and repeatably. It drops right into standard holders, so swapping lamps on the line doesn’t require custom brackets.
The Payoff: Drying Without Compromising Color
When you’re drying decorative glass ink, you’re juggling two needs: remove the water, and keep the color intact. Infrared heating targets the ink layer and the moisture inside it. That means you can run with lower overall energy and still hit the drying rate you need. The lamp delivers quick, localized heat, so you don’t overheat the substrate and risk color shift. Energy use drops because the heat goes where it matters—straight into the water—instead of heating up the whole chamber. You end up with a drier print, stable color, and a process that’s easier to control shift after shift.
