Each unit is positioned directly within the airflow, equipped with 4 to 24 high-output UV-C lamps, arranged in groups of 4 per module. The quantity of modules is tailored based on the required air volume to ensure appropriate irradiation levels. UVGI technology deactivates micro-organisms by damaging their DNA, which prevents them from replicating or growing. The UV-C light, ranging from 100 to 280 nm, is particularly effective for sterilization, with the peak germicidal wavelength at around 260nm being most effective against airborne and surface microorganisms.
