Out on the glass line, heat is more than just temperature. It’s timing, it’s distribution, and it’s repeatability. When an R7s lamp socket in a heater starts to drift, you know it instantly—uneven temper, edge wave on bent glass, or a slow ramp-up that throws the whole shift off. We built our R7s infrared heater modules for the shop floor as it actually runs, where uptime and kelvin-level control are the only metrics that matter. What matters under the hood The core is short-wave infrared using quartz lamps and an R7s connector, tuned for fast, directional radiation. You get a thermal field that stays even across the full width of the glass, and response is quick enough to follow setpoint changes without lag. Emissivity stays under control on coated and laminated assemblies, and the heat lands where you want it—on the surface—so you’re not dumping energy into the frame and the surroundings. Output holds steady through repeated thermal cycles, and the lamp geometry drops straight into standard heater blocks, so you can swap modules without redesigning the oven zone. In tempering and bending, uniform heat distribution keeps thermal stress fractures down and keeps optical quality in spec. In EVA/SGP/PVB lamination and coating drying, that fast response cuts dwell time and tightens the process window, so you can run thicker stacks without sacrificing throughput. The payoff is fewer rejects, cycle times you can count on, and lower kWh per square meter because you’re heating glass—not air and steel. Here are the practical details. Installation is straightforward on standard R7s sockets, but you still need to verify alignment and contact. Keep the reflectors clean and set the lamp focal distance to the glass surface; if you don’t, you’ll start seeing hot spots. Lamp life will always depend on power density and how often you cycle thermally—plan replacement intervals and keep spares on hand so you don’t get caught with an unplanned stop.
