Ensure properly disinfected air with Porex Virtek reflective media lining your UVC air disinfection products

With the recent heightened awareness around clean indoor air, utilizing a UVC system within an air handling unit is proving to be one of the most effective solutions.  UVC energy is proven to deactivate most pathogens; however, to be effective, the UV energy must be uniformly dispersed within the reaction chamber.  This is where Porex Virtek reflective media excels. 

Porex Virtek offers:

  • Reflectivity rates of up to 97%
  • Almost 100% Lambertian (diffuse) reflectivity
  • Extremely uniform energy distribution within the reaction chamber
  • Up to 4 times higher flux in a closed system versus aluminum

Traditional Aluminum lining

Reactor Chamber with Aluminum lining

Reactor Chamber with Aluminum lining

  • Typical Reflectivity around 70%
  • Specular reflection means hot and cold spots and uneven disinfection
  • The orientation and quantity of UV source becomes much more important
  • Energy needed for 3 log reduction increases
  • Average irradiance (E) = (Edirect) + (Ereflected) :If Reflectivity = 70%
  • At a source irradiance (E) of 1:  Average irradiance = 1 + (1 / (1-0.7))= 4.3

Optimal PTFE lining

  • Reflectivity of up to 97%
  • Reflects diffuses in all directions uniformly (minimal hot/cold spots)
  • UV orientation less critical
  • Energy consumption is lower
  • Average irradiance (E) = (Edirect) + (Ereflected) :If Reflectivity = 97%
  • At a source irradiance (E) of 1:  Average irradiance = 1 + (1 / (1-0.97))= 34.3
  • 8 times the average irradiance versus 70% aluminum!
