UV-C disinfection is not a new concept however, scientists are constantly discovering new ways to use UV-C radiation. The dosage and exposure time is modified based on the size and configuration of the room being sanitized, as well as any objects that may obstruct UV-C rays. UV-C mobile systems are specially designed to be safely and easily relocated for use in multiple locations. These fixtures are commonly used to prevent biofilm from forming in water reservoirs and to keep air treatment systems clean. UV-C disinfection systems are inexpensive to install, require very little maintenance, and are easy to operate. According to the National Institute of Health, the ideal wavelength to kill pathogenic microorganisms is 254 nm, so most UV-C fixtures are engineered to emit light at or near this range. The wavelength of UV-C rays falls between 100 and 280 nm. With the proper design, a UV sanitization system can provide up to a 99.9% microbial reduction in air that circulates through your HVAC unit. Simply adding a UV light may not be sufficient to provide adequate disinfection of both the coil and circulating air, as there are many critical factors that play into the amount of UV needed for proper sanitization within an HVAC system. HVAC condensing coils create the perfect moist environment for the growth of bacteria, mildew, and mold. Continuous circulation and exposure further reduces active pathogens in the room. UV fixtures on the upper level expose the pathogenic particles to UV radiation, inactivating those particles. Air circulation within the room causes microbes to float to the upper levels of the room. Upper-air UV fixtures are specifically designed to enhance indoor air quality by inactivating microbes such as viruses, fungi, and bacteria in the air, reducing the risk of flu, cold, allergies, and other illnesses.
The Different Types of UV-C Solutionsĭue to UV-C light’s ability to provide reliable and powerful sanitization at a low cost, numerous designs have been developed to meet the needs of various applications. UV sanitation also uses very little energy. The initial installation is inexpensive, and the equipment is low-cost and easy to maintain. With UV light disinfection systems, you don’t have to keep spending money on chemicals and cleaning materials. Whether you are in need of a mobile UV disinfection device for surface disinfection or a permanent sanitization installation in a ventilation duct, there are numerous options tailored to a wide variety of applications. UV radiation provides reliable and safe sanitization that not only prevents the development of new resistant strains, but is effective against pathogens that have developed resistance to other antimicrobial measures.
Unlike antimicrobial chemicals, UV disinfection does not facilitate microbial immunity. When directly exposed to UV-C radiation, the genetic material of viruses and bacteria is compromised, preventing pathogens from multiplying and spreading. UV-C light is an extremely effective means of disinfection and sanitization. It can be used to sanitize surfaces and can be safely used in air and water filtration systems.
When appropriate precautions are taken, UV-C disinfection is a safe and non-toxic alternative to more traditional chemical sanitizers.
