Ultraviolet Germicidal Irradiation is a Proven Method for Effectively Inactivating Mold, Bacteria, and Viruses
The C Wavelength of the UV Spectrum targets the DNA of Microorganisms,
destroying their cells and making replication impossible.
Germicidal UVC Solutions
Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet light (UVC) to kill or inactivate microorganisms. UVC improves indoor air quality (IAQ) while increasing operational efficiency, reducing maintenance costs and saving energy.
UVC light installations for HVAC systems can be applied in two ways: in-duct airstream disinfection and air handler component surface disinfection.
Airstream and Coil Disinfection
High-output UVC lamps are designed to deliver UV doses for airstream disinfection. In-duct airstream applications require minimal space and are easy to install in both existing and new equipment. These systems disinfect air as it passes through the HVAC system and reduce airborne infectious microorganisms that spread illness.
UVC for coil disinfection utilizes coil-mounted fixtures that target the coils and drain pans of the HVAC system.
UVC lamps target cooling coils, condensation pans, and filters. This allows for healthy air supply by destroying bacteria and mold that grow on the moist surfaces in tough-to-reach areas such as grooves, fins, seams, and edges.
Based on your current equipment and space usage, Donnelly Mechanical will determine the best UVC application for your system.

The SAFEST Mechanical Contractor in New York City
We retained Donnelly Mechanical to provide a turn-key replacement of obsolete air handlers. We provided the basic performance specifications we needed for the areas the equipment would serve and they did the rest from shop drawing to unit commissioning. They acted as general contractor and retained the services of all trades necessary to execute the work. Existing chilled water and steam risers required modifications as did electrical infrastructure. The project manager was present every day that work took place. He provided daily briefings on progress. Every aspect of the project was meticulously planned. The equipment being replaced was the original and thus this project presented challenges that were not a factor at the time of original installation. Everything had to fit within confines of mechanical rooms and provide adequate clearances as necessary for persons to work. I have heard tales of woe about equipment arriving at loading docks and then not fitting in the elevator, not fitting through the door, not making the turn, etc. Donnelly brought a representative from the equipment manufacturer to the site to walk the route from the street to the mechanical room so that every doorway, corridor, elevator, turn, etc was accounted for and thus there were no logistical issues that often arise in a large-scale project. All tradespersons displayed professionalism throughout and were very respectful of the property.
