Silanna UV launches NozzleShield UV water dispenser disinfection technology
Silanna UV of Brisbane, Australia – which provides far-UVC light sources for water quality sensors, gas sensors, disinfection, and HPLC (high-performance liquid chromatography) applications – has launched the NozzleShield UV water dispenser disinfection application. The technology uses 235nm-wavelength UV-C LEDs to rapidly disinfect water dispensers, effectively eliminating bacteria and virus buildup. This ensures that water dispensers remain free from harmful bacteria, benefiting companies aiming to enhance their product features.
Many studies demonstrate the effectiveness of far UV-C against various pathogens, including SARS-CoV-2. In fact, studies carried out in 2023 at Italy’s University of Siena specifically confirmed the powerful biocidal disinfection properties of the 235nm far UV-C output emitted by Silanna’s UV-C LEDs. These tests showed the UV-C technology swiftly killing 99.9% to 99.99% of dangerous bacteria that commonly cause harm to humans, including E. Coli, S. Aureus and P. Aeruginosa. These bacteria are often responsible for dangerous outbreaks of food poisoning and other infections.
To further improve the efficacy of the technology, additional far UV-C LEDs can be carefully positioned to enhance the disinfection of water dispenser nozzles, which are easily contaminated.
Silanna UV is showcasing the technology in booth 01.614 (Hall 1) at Aquatech Amsterdam 2025 in The Netherlands (11–14 March).
