Introduction
We built this infrared heating lamp for one specific job: drying solar glass coatings right after the ink is printed. You know that maddening bottleneck where the glass is too wet to stack? This solves it. It gets the surface dry in seconds, so the glass can move to the next step immediately. No more worrying about sheets sticking together. Just smooth, immediate turnover.
The Tech, Without the Fluff
Here’s the core of it: we used a shortwave infrared halogen design. It’s all about delivering the kind of power density that makes fast surface curing possible. It runs on a 400V supply and pulls 2500W through a compact 300mm tube. That tight power-to-length ratio is intentional. It concentrates the heat into a small footprint—just wide enough to match the printing exit lane. So you get a focused blast of heat hitting the wet coating the second the glass leaves the press. Not spread out. Just right where you need it.
Built to Last
The tube itself is wrapped in a quartz envelope with a special coating. It keeps the output steady and can handle the stress of rapid on-and-off cycling without blinking. Inside, the halogen filament runs hot on purpose. That’s what creates the shortwave IR that dives into the wet ink without scorching the glass underneath. And for the install? We kept it simple. The R7s connector is a standard fit, so it drops right into most existing mounts. You just wire it up—no retooling the machine. The Sk15 terminal block takes the 400V input cleanly, so the connection stays rock solid, even when the line is running nonstop.
How It Works on the Floor
On a solar glass coating line, this lamp sits right after the printing stage. Its job is second-level surface drying. The shortwave IR energy dries the ink surface in seconds, wiping out that tacky feeling that causes sheets to stick when stacked. That means far fewer scrapped pieces from adhesion defects. And honestly? It keeps the whole line moving at the pace of the printer. Now, one thing to keep in mind: that 2500W density packs a punch. You do need a properly spec’d cooling setup. Make sure the airflow and shielding are planned, so the lamp and the electronics nearby stay cool under pressure.
