How Does UV work?

UV Spectrum

UV WORKING PRINCIPLE

UV sterilization is to destroy and change the DNA structure of microorganisms through UV radiation. Virus or Bacteria will die immediately or can not reproduce the offspring so as to achieve the purpose of sterilization. UV-C light is with bactericidal effect because C wavelength UV light can be easily absorbed bu organisms DNA. 253.7nm wavelength UV light is the best.

Our UV products adopt a new generation of UVCPTM (Ultraviolet C Purification) technology to sterilize airflow in air duct. Our products use high quality, long life and high-intensity UVC lamps. Our Lamp Life is >9000 hours. UVC output is stable about 95% of UV energy output is with 23.7nm wavelength, which can effectively kill all kinds of pathogenic microorganisms.

UV APPLICATION FIELDS

  • HVAC SYSTEMS
  • WATER TREATMENT SYSTEMS
  • CENTRAL AIR CONDITIONING SYSTEMS
  • FOOD SAFETY
  • COMMERCIAL KITCHENS

 

BENEFITS OF UV TECHNOLOGY

  • UVC radiation has been proven to be effective against waterborne pathogenic microorganisms including those responsible for cholera, hepatitis, polio, typhoid, giardia, cryptosporidium and many other bacterial, viral and parasitic diseases
  • UVC radiation can be used to destroy chemical contaminants such as pesticides, hormones and other pharmaceuticals in drinking water or wastewater
  • UVC installations have low capital and operation cost
  • UVC technology is environmentally friendly
  • UVC installations are easy to operate and to maintain
  • UVC radiation has no harmful effect when overdosed
  • UVC radiation works instantly and the effectiveness does not depend on the water temperature
  • UVC disinfection is a physical process: no substances are added to the water
  • UVC disinfection is complementary to Chlorine disinfection: it deactivates organisms that are resistant to Chlorine such as giardia and cryptosporidium
  • UVC lamps can be easily regulated to optimise treatment for variations of water quality and for changing water flows
  • UVC radiation will keep the surface of reservoirs clean from biofilm
  • The UVC disinfection effect is directly related to the UV dose (which is the product of intensity and exposure time of the micro-organisms) so it’s effectiveness can be simply measured once the system design is validated
