UV Disinfection – HVAC Ducts and AHUs
Ultraviolet light in the c-band range (225–302 nm) is lethal to micro-organisms and is referred to as ultraviolet germicidal irradiation (UVGI). UVGI works by cross linking nucleic acids (DNA & RNA) to prevent replication and proliferation of micro-organisms such as viruses, bacteria, spores, moulds, yeast and fungi. UVGI is widely used in central air conditioning and ventilation systems to disinfect the indoor air and thus to improve air quality.
Air Treatment in building ventilation
Techniklean UVGI
Highly efficient, high output in-duct UVGI units produce high intensity UV-C light at 254nm and boast an operating life of up to 10,000hrs. TechniKlean UVGI units are the perfect solution for introducing UVGI technology into new and existing ductwork. Finished in Grade 304 stainless steel and weighing just 3kg, the compact unit can be installed into ductwork via an access panel or into a purpose built unit or AHU accordingly.
Surface Treatment of heat exchange coils
Coilklean UVGI
Microbes growing and forming biofilms on heat exchange coils causes reduction in the heat exchange efficiency resulting in higher running costs. Manual cleaning damages the coils but by exposing the coils to constant UV-C light, biofilm growth is prevented.
CoilKlean UVGI keeps the coil clean, perpetually disinfecting 99+% of viruses, bacteria, mould, spores and fungi. Not only does this eradicate microbial growth, but it also helps to maintain optimum heat transfer across the coil surface and maximises energy efficiency.
