On the coating line, the bottleneck is rarely the applicator. It’s the dry. When drying is slow or uneven, cycle time drags, and those thermal swings come back to haunt you later—micro-defects, haze, and adhesion that misses the mark. We built a glass coating drying lamp to clear that constraint with repeatable, measurable heat. What matters under the hood This unit leans on short-wave NIR emitters inside a quartz envelope, tuned to dump energy fast into thin organic and hybrid coatings. It climbs from ambient to operating temperature at 15°C/s, so you can jump back online without waiting around. Across the active drying zone, you get ±2°C uniformity, which cuts the thermal gradients that can stress tempered or bent glass. Power density hits 45 kW/m², delivering high photon flux with low thermal inertia—less lag, quicker response. We spec 400 V three-phase, compact mounting dimensions, and standard industrial connectors so it drops in like a module, not a re-engineered headache. Why it plays in glass processing In glass work—coating, lamination prep, and IG sealing—time and temperature control are the knobs that move yield. With this lamp, you shrink the drying window, trim oven dwell, and steady adhesion. The payoff is fewer reworks, more consistent optical clarity, and more parts per shift. Energy use drops, too, because NIR targets the coating directly, with minimal wasted heat on the glass body and the surroundings. The practical bits The lamp cares about line-of-sight and emissivity. Reflective tooling or varying glass tints change absorption, so we recommend a short setup window to map power and dwell for your exact coating stack. Keep the quartz window clean and dry; heavy dust or solvent residue will scatter light and rob output. Plan for 30 minutes to align and map temperatures during commissioning, then lock in the recipe.
