As we are stabilizing from the pandemic, employees are continuing to move back into the physical workplace and open businesses to customers. Updated cleaning protocols and proactive sanitation and disinfection measures will be a part of businesses cleaning routine. In particular, industrial disinfection cleaning services are more important than ever to the health and safety of your employees. That’s why continuing to sanitize and disinfect your facility will help to reassure people who are making their way back out into the workplace. UVC light in HVAC is one of the best ways to help clean and disinfect your facility’s ventilation system.

What Is UVC Light Disinfection for HVAC System

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.

UVGI for HVAC systems utilize Germicidal lamps to sterilize workspaces and tools used in pharmaceutical manufacturing, food production facilities and other production facilities. This method of disinfection uses a short-wavelength ultraviolet light to kill or inactivate microorganisms, leaving them unable to perform vital functions. Germicidal lamps are used to sterilize workspaces and tools used in biology laboratories and medical facilities.


How UVC Lighting at the Coil Works?

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

In fact, according to the World Health Organization (WHO), approximately 30% of all commercial buildings have significant IAQ problems, and ventilation systems are implicated in the spread of infection and pollutants.” Therefore, using UVC light in a facility’s duct system close to the coil can restore coil capacity, return the HVAC close to the original system, and kill bacterial growth by shrinking biofilm on the coil.


UVC Lighting at the Coil Benefits

Germicidal lights are simple, effective ways to curb bacterial and viral growths. These 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.
