The first documented application of UV for the purpose of disinfection was a 1910 prototype drinking water plant in Marseille, France1. MOLD SPORESĮssentials of Germicidal Irradiation for Reduction of Microorganisms The values shown under the percentage kill are in microwatts per square centimeter of UVC energy. Mold spores are generally much more difficult to inactivate than microorganisms and viruses and, thus, require a much higher dosage of ultraviolet light. You can find the target dosage for most common mold spores in the following table.
In addition, UVC Germicidal Fixtures play a very important role in improving air quality and will eliminate the awful odor and slimy build up associated with mold and bacteria that thrive when temperatures are between 50-100F (especially when moisture is present).įor HVAC applications, just as with all other UVC disinfection applications, direct exposure to 254nm UVC radiation, given appropriate exposure time, will inactivate the DNA and RNA of microorganisms, rendering them unable to reproduce.Ī lethal dose of UVC energy is determined by the total amount of UVC energy a microorganism "sees." This is a "dosage." Dosage is a product of the intensity of UVC radiation (expressed in microwatts per square centimeter) and exposure time to that radiation. They'll often pay for themselves in months and can help you save many thousands of dollars in on-going energy and maintenance costs. UVC Germicidal Fixtures keep coils clean all of the time, enabling HVAC systems to perform as originally intended, and ensuring: Steam cleaning can actually force growth deeper into the fin pack, compressing it so tightly that the only solution could be to replace the coil. Cleaning also frequently leaves material embedded in the center of the fin pack. Without UVC, coils require constant cleaning, an expensive and inferior process that often relies on toxic and/or flammable solvents that are dangerous, and that can diminish the life of the coil. Using UVC Germicidal Fixtures from American Ultraviolet Company, on the other hand, is a permanent solution. Back to top Filters and Coil Cleaningįilters are necessary to trap dust, pollen and other particles, however, to remove harmful bacteria and viruses from the air stream you need the addition of UVC light to render these microorganisms sterile, and therefore unable to reproduce.Ĭleaning coils is like treating symptoms. For more than 60 years, tens of thousands have been safely installed in hospitals, clinics, processing plants, commercial offices, manufacturing sites and other commercial facilities and multi-and single-family residences around the world.
UVC Germicidal Fixtures are a labor-free solution that will not harm occupants, equipment, or furnishings because they produce no ozone or secondary contaminants.
