The Need for Speed in Glass Finishing
On a high-gloss line, you can’t afford to baby the glass. The annealing window is tight, and the whole line moves at the pace of its slowest point. If your dryer doesn’t hit temperature instantly and hold steady, you lose control of the luster and stress in the glass. That’s why we built our high-gloss finish dryer around a rapid-response infrared halogen lamp. It turns heat into something you can count on, over and over.
Power and Voltage: Matching the Load to the Line
Here’s the core setup: 400V, 2500W, 300mm. No random numbers here. The 400V feed keeps the current lower than a 230V design at the same wattage. That means smaller conductors and less voltage drop over distance. The 2500W packed into 300mm gives you the heat flux needed to close the gap between heating and cooling zones. But there’s a trade-off. That much power density demands a cooling and airflow plan that’s properly thought through. You have to keep the quartz and reflector from running too hot, or you’ll pay for it down the line.
Material, Coating, and the R7s Connection
The tube is quartz, plain and simple, because it can handle thermal shock and stay stable at high heat. The halogen fill keeps the filament stable over its life, so output stays consistent instead of fading over time. Inside, a reflective coating pushes more energy forward. Less wasted heat. More intensity where you need it—on the glass. And the R7s connector? It’s the practical choice on the shop floor. It locks in fast, handles the current, and lets you swap the lamp without rewiring the fixture. Just drop it in and go.
On-Line Annealing and Continuous Run
When you’re doing on-line annealing, response time is everything. Infrared halogen lamps come up to temperature in seconds, so you can sync the heat to the glass, not to some slow, bulky thermal mass. The result? Stress relief that stays stable, gloss that stays consistent, and fewer slowdowns. And when you need to keep running, the lamp is built as a replaceable module. Wire it up, set the focus, and keep moving. The footprint is small, the control is direct, and the uptime is exactly what you need when the line is counting seconds.
