Air Disinfection with UV-C Technology
Pathogen and chemical air contamination is one of the top 5 health risks in the world according to the World Health Organization (WHO, 2005). Air pollution related risks range from indoor discomfort and mild health problems up to severe health risk and in serious cases death. Respiratory diseases are thought to be responsible for around 10% of all deaths worldwide (WHO, 2005), with infectious diseases such as tuberculosis a major contributor.
In this Covid-19 era, the air purification is a rapidly growing market and we are the professional team to provide most reliable EPA tested* products for wide variety of HVAC ventilation systems.
*The U.S. Environmental Protection Agency (EPA).
The INFO section provides a brief introduction to our engineering-level Research & Development steps and its verified empirical tests.
UVAVE equipment is designed specifically to the client’s application/needs
Specifying a UV-C system to treat an air flow in a duct is NOT a simple process. UVAVE equipment is designed specifically to the client’s application/needs and it depends on several variables as followed:
Target micro-organism and required minimum log reduction**, Air flow, Duct dimensions and its materials, Air temperature range, Upstream filtration efficiency, Duct function (HVAC System type), to mention just a few.
**UV-C dose required to kill microorganisms:
90% (1 log) reduction
99% (2 log) reduction
99.9% (3 log) reduction
99.99% (4 log) reduction
99.999% (5 log) reduction
99.9999% (6 log) reduction
What makes our products being unique?
UVAVE Engineers have developed unique engineering tools to accurately predict the accurate in/out log reduction while verified by EPA presented lab results and Empirical Tests.
Our products have several development stages:
uv-c lights
The C wavelength of the UV spectrum targets the DNA of microorganisms, destroying their cells and making replication impossible. Directed at a cooling coil or drain pan, UVC energy destroys surface biofilm, a gluey matrix of microorganisms (bacteria, fungi, debris, et al.) that grows in the presence of moisture. Biofilm is prevalent in HVAC systems and leads to a host of indoor air quality (IAQ) and HVAC operational problems that are sometimes mistakenly attributed solely to mold. UVC also destroys airborne viruses and bacteria that circulate through an HVAC system.
By applying the power of UVC at the source of contamination – the HVAC evaporator coils and drain pan – Sterile-Air UVC destroys the reservoir of microorganisms. Without the ability to reproduce, microorganisms become inactive and harmless. The recirculating air in HVAC systems creates redundancy in exposing microorganisms to UVC, ensuring multiple passes so the light energy is effective against large quantities of airborne microorganisms. Steril-Aire UVC delivers the highest UVC output, driving HVAC system efficiency while improving indoor air quality.
For large or critical applications, change out should be performed when Emitter output decreases by 40% as measured by a radiometer, after about 9,000 hours or 12 months. For installations with no radiometer, change Emitters annually (after about 9,000 hours).
The UVC Emitters are warranted for 1 year (9,000 hours).

Ultraviolet (UV) light is one form of electromagnetic energy produced naturally by the sun. UV is a spectrum of light just below the visible light and it is split into four distinct spectral areas –Vacuum UV (100 to 200 nm), UVC (200 to 280 nm), UVB (280 to 315 nm) and UVA (315 to 400 nm).
The entire UV spectrum can kill or inactivate many microorganism species, preventing them from replicating. UVC energy at 253.7 nanometres provides the most germicidal effect. The application of UVC energy to inactivate microorganisms is also known as Germicidal Irradiation or UVGI.
The C wavelength of the UV spectrum targets the DNA of microorganisms, destroying their cells and making replication impossible. Directed at a cooling coil or drain pan, UVC energy destroys surface biofilm, a gluey matrix of microorganisms (bacteria, fungi, debris, et al.) that grows in the presence of moisture. Biofilm is prevalent in HVAC systems and leads to a host of indoor air quality (IAQ) and HVAC operational problems that are sometimes mistakenly attributed solely to mold.
UVC also destroys airborne viruses and bacteria that circulate through an HVAC system
In addition to reducing HVAC-surface and airborne bacteria, germicidal UV can be used to supplement and improve other infection-control strategies, such as room air exchange. When a required number of air changes per hour (ACH) cannot be achieved using outside-air ventilation alone, upper-room UV systems can perform germicidal “equivalent” ACH. “It has been estimated that when an average UV intensity of 10 µW/cm2 is present in the upper room, 63 percent of airborne tuberculosis germs that arrive there will be killed in 24 sec (the germicidal equivalent of one room air change), and, therefore, 99 percent will be killed in 2 min (equivalent of five air changes).” This is important, as pathogenic aerosols can be spread through HVAC systems.
UV-C can supplement protocols for disinfection, sterilization, and manual cleaning, providing a level of protection in the event a protocol fails.
