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 in Figure 1.
This light can be further categorized into separate regions as follows:

How Does Germicidal UV Work

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)

What is a UV Dose?

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.

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 proportion 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

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.

Details

  • Solid design, 2mm thick aluminum 
  • Integrated UVC LED and Blue LED indicator lights
  • Kills 99.9% of bacteria
  • BAA compliant

Stella Aire UVC Panel

The Stella Aire UVC Panel combines LED technology with UVC and is manufactured using a coherent welding method and our solid-state UVC light panels are subject to an antistatic treatment making the panels resistant to dust. 

Features:

The UV-C Light panel uses beveled edge design, a seamless welding process, white paint on the surface, anti static treatment and is easy to clean. The frame is made of 6063 aviation aluminum material with high thermal conductivity, which is convenient for heat dissipation and reduces the decay of the lamp. The spectrum of the lamps is completely free of ultraviolet and blue light, meeting the requirements of green lighting.  Installation is simple, maintenance costs are reduced, and lifetime is up to 50,000 hours.

Details

  • Can be quickly surface-mounted 
  • Easy to clean and install
  • Reduced maintenance and replacement costs
  • CE and RoHS Certified

The Stella Aire UVC Cannon is specially designed to sanitize larger rooms. Our high-intensity UV-C Cannon, features electrodeless fluorescent UVC tubes that kill 99.99% of germs, viruses, bacteria, microbes, mold spores, fungi, salmonella, the flu, and more. The UV-C Cannon is not only useful for sanitizing surfaces but air as well.

How Does It Work?

Wheel the Stella Aire UVC Cannon into the room and then close all doors and windows. Plug the unit into a power outlet and select the desired disinfection time and press the power button. The Stella Aire UVC Cannon’s timer can be set to be on for up to 120 minutes, but on average, only 6 minutes is needed.
