Germicidal UV-C Light Systems
Sanitize not only the air but the coils, drain line and even the ductwork.
The unique germ-killing properties of UVC Disinfection light have been known for over a century. Since UVC in sunlight is filtered by the Earth’s atmosphere, microbes (including viruses) have no defense against it.
We install Germicidal UVC light systems in the central air system where it sterilizes airborne viruses and bacteria – including COVID. The system also suppresses mold growth on the cooling coils and surrounding areas while generally improving indoor air quality throughout the space.
Chemical-free technology used for hospital disinfection, food safety, and water purification.
UVC light disinfection is widely used in hospitals and labs to sanitize instruments and work surfaces to prevent the spread of potentially lethal airborne infectious diseases. Also, it is used by the food industry to sterilize food before packaging and water treatment systems.
Are all UVC Systems the same?
No, our In-Duct PCO Photocatalytic Oxidation UVC Air Purifier (254nm) works to keep the air in your office’s air ducts clean and pure by combining the molecular reaction of ultraviolet light with titanium dioxide (TIO2) – which is NEXT LEVEL for HVAC-UVC systems. These systems destroy organic threats, and remove harmful VOCs and noxious odors with this most advanced purification system yet.

What is UV-C Light?
Ultraviolet (UV) light is a range of light frequencies that are mostly invisible to the human eye. The UV-C band is most effective at killing germs because its short wavelength is able to penetrate the cell walls of microorganisms and scramble their DNA. Also, UV-C is filtered out by the earth’s atmosphere so microbes have no defense against it.
Safe & Effective Disinfection
For over a century scientists have known that certain frequencies of light have a devastating effect on microbial life. We now know that exposure to ultraviolet light in the range of 254 NM (UV-C band) disrupts the DNA of micro-organisms thus preventing them from reproducing, thereby effectively killing them.
UV Light – A Well Established Disinfection Technology
UV light disinfection is now widely used in hospitals and laboratories to sanitize instruments and work surfaces and to prevent the spread of potentially lethal airborne infectious diseases. The technology is used by the food industry to sterilize food before packaging and water treatment systems large and small now incorporate UV light as a chemical-free means of purification.
Kill Germs With Light
Because the frequency of UV-C light is filtered out by the Earth’s atmosphere microorganisms have no defense against it. It works by scrambling their DNA which prevents them from reproducing.
Improve Indoor Air Quality
According to the EPA, indoor air pollution is often five times worse than outdoor and represents a significant health risk. UV-C improves indoor air quality by sterilizing mold, bacteria, viruses, and allergens from the air as it cycles through the central air system.

Ultraviolet Energy (UV-C)
- Ultraviolet energy inactivates viral, bacterial, and fungal organisms so they are unable to replicate and potentially cause disease.
- The entire UV spectrum is capable of inactivating microorganisms, but UV-C energy (wavelengths of 100 – 280 nm) provides the most germicidal effect, with 265 nm being the optimum wavelength.
- The majority of modern UVGI lamps create UV-C energy with an electrical discharge through a low-pressure gas (including mercury vapor) enclosed in a quartz tube, similar to fluorescent lamps.
- Roughly 95% of the energy produced by these lamps is radiated at a near-optimal wavelength of 253.7 nm.
- UV-C light-emitting diodes (LEDs) are emerging for use.
- Types of disinfection systems using UV-C energy:
- In-duct air disinfection
- Upper-air disinfection
- In-duct surface disinfection
- Portable room decontamination
- Requires special PPE to prevent damage to eyes and/or skin from overexposure.
- The Illuminating Engineering Society (IES) Photobiology Committee published a FAQ on Germicidal Ultraviolet (GUV) specific to the COVID-19 pandemic.
