What is UV Light?

UV light is a component of sunlight that falls in the region between visible light and X-rays on the  electromagnetic spectrum, with a wavelength range of 100 – 400 nanometers (nm), as shown below.  This light can be further categorized into separate regions as follows:

 > UVA: 315—400 nm
 > UVC: 200—280 nm

> UVB: 280—315 nm

> Far UV (or “vacuum”): 100—200 nm

How Does Germicidal UV Work?

Radiation in the UVC range of 250-280 nm deactivates bacteria, viruses, and other microbes by attacking their DNA. UVC light penetrates the cells of microorganisms and disrupt the structure of the DNA molecules. It does this by destroying the genetic information inside the DNA (Figure 2). The microorganisms, in turn, lose their reproductive capability and are destroyed, rendering them inactive and no longer harmful. The germicidal nature of UV is well suited to treat microorganisms which become extremely resistant to chemical disinfectants, as they are unable to develop immunity to UV radiation.

What is a UV Dose?

Different pathogens have unique resistances to UV light—some are very susceptible, while others require more UVC exposure for complete inactivation. A correct UV dose is critical to thoroughly deactivate the intended microbes.
UV dose, also called UV fluence, is calculated using the following equation:

UV Dose = UV Intensity (I) x Exposure time (t)

UV Dose Response

The UV dose-response relationship determines what proportion of a specific microorganism is  destroyed after a particular dose of UV radiation. This figure can be expressed as either the p  roportion of microorganisms inactivated or the proportion remaining as a function of UV dose.  The UV dose-response is calculated using the following equation:

Stella Aire UVC for Disinfection

Stella Aire UVC for Disinfection UV radiation can be an incredibly effective resource for disinfection applications, and Ecostella has created a unique product that overcomes obstacles traditionally associated with UV light sources. Its lifetime expectancy and reliability can exceed other UV light sources, and the instant on/off feature which is inherent to solid state devices (unlike its plasma gas counterparts) can contribute to a an even longer lifetime. The Stella Aire UVC LEDs are safe and eco-friendly and offer design flexibility that other UV sources cannot match. The benefits of the Stella Aire UVC products make UV disinfection a very efficient, cost-effective option in disinfection applications.
The Stella Aire UVC Light Bar combines the power of UVC light with the latest technology in LED’s in order to bring a high quality, effective solution to indoor sterilization.

How Does It Work?

The Stella Aire UVC LED Light Bar is an effective solution for UVC sterilization that installs directly in the air handlers of both residential and commercial HVAC systems. Stella Aire uses UVC LED technology to sterilize the air circulating through the system and contains the necessary wattage to do so effectively.
