UVC Light for HVAC Systems to Disinfect Ducts Blog Image

For many companies in the industrial industry, you might be facing the shutdown season for proper environmental cleaning. One of the services that should be included during this routine period is commercial duct cleaning.

Dust in the ductwork or coils can let microbes or fungus grow, which can be a health hazard when it blows through the building. But we all know that routine commercial duct cleaning is the first step in removing airborne contaminants and allergens out of the air you breathe. However, another great way to ensure your facility’s ventilations system is clean and healthy is through the installation of UVC Lighting.


What Is UVC Light?

UVGI for HVAC systems is a disinfection method that uses short-wavelength ultraviolet light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. UCGI refers to ultraviolet light with wavelengths between 200 – 280 nanometers (nm). Light in the UVGI wavelength can be used for disinfecting duct work, sterilizing surfaces, destroying harmful micro-organisms in food products and in air.


How Does UVC Light Work?

UVC lighting at the coil (also known as In-duct UVGI systems) are mounted inside AHUs or ventilation ductwork. When selected to produce appropriate irradiance levels, in-duct systems can be effective for air disinfection. An in-duct air disinfection system inactivates microbes suspended in the air (e.g., viable influenza viruses) as they move through the duct or AHU, so the organism is no longer capable of causing and spreading disease. Not only that, but UVC in HVAC is designed to save energy and maintenance costs associated with the ventilation Systems. Mold (biofilm) on coils of only 0.002 can reduce efficiency by 37%. Ultraviolet germicidal irradiation (UVGI) is the most effective and practical solution for industrial facilities. Since they are installed close to the coil, UVC light can help to restore coil capacity. It also has the ability to return HVAC systems close to the original system, while also killing bacterial growth by shrinking biofilm on the coil.


Benefits of Using UVC Light Systems?

UVGI specialized lamps produce an ultraviolet (UV) light that disrupts growth and deactivates existing growths, aiding in the disinfection of surfaces, water and more. Using one in your production facility can help improve everything from air quality to the health and well-being of you and your occupants. By treating the air circulating in your heating and cooling system, UV germicidal lamps can kill mold and destroy airborne viruses and bacteria that, ultimately, lead to colds, flus and other illnesses. This can keep you and employees healthy.
