On the insulating glass line, edge sealant drying is the quiet choke point that sets your throughput and scrap rate. If the lamp can’t keep up, the beads stay tacky, dust grabs on, and the secondary seal gets flagged. We built this drying lamp for the line floor, not for a lab bench.
What matters under the hood
We run short-wave NIR (quartz) emitters that put the heat right where it needs to be—on the sealant—so you don’t waste energy heating the sash. Start-up is fast: full output in 3 seconds, so the line doesn’t sit and wait. The heating window stays repeatable: ±2°C across the emitting length, which keeps thermal stress off the glass and helps you avoid micro-cracks. Power density hits 45 W/cm², giving you the flux needed to drive solvent evaporation at line speed. Power is adjustable from 30% to 100%, so you can match thin spacers and thicker profiles without temperature overshoot.
Why it holds up in production
You need the edge bead cured before contamination finds it, and you need the sash moving. This lamp dries the bead quickly and evenly, so the secondary seal applies clean and the IG unit passes pressure and dew-point tests. The payoff is fewer rejects, less rework, and more units per shift. Energy use drops because NIR heats the sealant, not the air, and the fast response cuts idle power.
Field notes that save headaches
Mounting is straightforward, but clearance is the detail that bites you. Keep 120–150 mm from the glass surface to keep flux uniform; outside that window, drying turns uneven. The unit runs on standard 230 V three-phase, and emitter life is rated to 5,000 hours. Expect a touch of temperature drift at the ends of long emitters—run a calibrated pyrometer on the first pass and lock the setpoint.
