Dark, warm, humid ductwork is where bacteria, mould and biofilm thrive — then your AHU distributes them through the whole building. UV-C built into the duct or air-handling unit inactivates micro-organisms continuously as the air passes, keeps coils and heat exchangers free of biofilm, and tackles the "sick building" complaints that follow. No chemicals, no filter penalty.
A room air purifier cleans the air in that room. UV-C in the air-handling unit cleans the air feeding every room — and stops the ventilation system itself becoming the reservoir. Cold registers, heat exchangers, condensate pans and humidifier water are exactly the dark, damp surfaces where biofilm, mould and Legionella establish. A UV-C barrier holds them clean, which also cuts filter replacement, plant cleaning and the energy penalty of a fouled coil. These are retrofit units that install from outside the duct, so most go in without major works.
From in-duct lamp batteries to AHU component protection and condensate-water sterilisation — sized to almost any duct, with per-emitter monitoring. All priced on application.
Sizing depends on your duct dimensions and air speed — send us the AHU details and we'll specify the right module count and lamp output.
In-duct UV-C dose depends on lamp output and how fast the air moves past it. Tell us your AHU and we'll model the delivered dose; the UV-C dose calculator shows how dose maps to log reduction.
Give us your duct dimensions, air speed and the problem you're solving (biofilm, Legionella risk, sick-building complaints) and we'll specify the modules, lamp output and retrofit adapters. Priced in your currency.
