UV lamp cooling fan system

When you’re running at 600 fpm, the mercury lamp’s spectral output and reflector geometry are only as good as the thermal management behind them. Let it run hot, and the 365 nm peak drifts, irradiance flattens, and the lamp starts dying early — while you’re still seeing cure defects on the substrate.

What actually matters, technically

We size airflow to the lamp power and the quartz envelope limits, not to what the room thermometer reads. The cooling system is there to keep the electrode junction inside the lamp’s rated window, so peak irradiance at the cure plane stays steady across the whole run. Airflow is balanced to kill hot spots at the reflector apex without letting lamp temperature swing all over the map. That’s how you preserve the spectral profile your photoinitiators need, keep cross-linking repeatable, and stop thermal drift from showing up as pinholes, adhesion loss, or ink that stays tacky.
