Ultraviolet C: A Natural Solution for Airborne Pathogens

November 02, 2020

The safety and purity of the air we breathe indoors has never been more important. We want confidence that in every indoor setting, from our workplaces to businesses we visit, the air we breathe will be free from dangerous bio-contaminants. That’s why McElroy’s is proud to be a leader in the design and installation of Ultraviolet C (UVC) air sterilization systems – helping to ensure that the air that fills our customers’ buildings is safe.

New Construction or Retrofit

Whether we’re designing UVC air sterilization into a completely new ventilation system or integrating it into your existing ductwork, the HVAC experts at McElroy’s will engineer a completely customized UVC air sterilization system. It will be optimized specifically for your ventilation system’s duct volume, velocity, configuration and internal reflection factor. No one understands HVAC innovation better than McElroy’s.

Proven Technologies

McElroy’s has done our homework and we work with the best, scientifically proven UVC air sterilization systems. Systems we specify are recommended by the Centers for Disease Control (CDC) to inactivate airborne pathogens, supported by ASHRAE standards, and backed by peer-reviewed scientific articles supporting the technology. McElroy’s installs affordable systems made to maximize the contact time with the UVC rays, to disinfect 99.99% of the air in a single pass – with virtually no effect on the speed and quality of overall airflow.

Verified Kill Rate

We can arrange for scientific testing of your precise system, to provide you with a verified sterilization kill rate report. This gives you the documentation you need to ensure that the utmost has been done to create the safest indoor air quality possible.

How Ultraviolet C Air Sterilization Works

Ultraviolet (UV) Light is a form of light that is invisible to the human eye. In certain wavelengths, it attacks the molecular structure of micro-organisms to deactivate and destroy them. The UV wavelength of 254nm is ideal for this purpose and is called UVC. Another UV wavelength, 185nm known as UVV, is most effective for degrading chemicals and odors that arise from contaminants.

In-duct UV Systems

UVC lamps are strategically placed within the ductwork that controls the flow of air within buildings. Anodized aluminum reflectors help focus each lamp’s rays to intensify and maximize the UVC energy. As the air passes closely along the length of these lamps, the UV rays do their work, destroying bio-contaminants as they flow by and purifying the air.

Proven Effective

Ultraviolet air and surface sterilization systems have been in use for more than 50 years in hospitals and other healthcare environments. The combination of advances in UVC technology and applications, coupled with the health and safety concerns of today, have made this an increasingly valuable option for purifying air in nearly any indoor environment. Count on McElroy’s to customize this powerful technology for your specific needs – and ensure the safety and purity of your indoor air.
