With new research stating that SARS-CoV-2 – which is causing COVID-19 – can remain infectious for up to 3 hours as it floats in aerosol droplets less than 5 microns, moving beyond the standard disinfectants and sanitization is important.
It is a known fact that spores, mould, bacteria, fungus and even viruses (including Coronavirus) can grow exponentially in HVAC systems (Heating, ventilation, and air conditioning). This can create an unhealthy environment on the premises as the virus, bacteria, etc can be transmitted through the air-conditioning ducts. Thus, here one of the best ways to curb this transmission and disinfect the air and indoor spaces is to use the Ultraviolet Germicidal Irradiation (UVGI) System for air purification.
ASHRAE (American Society of Heating, Refrigerating and Air-Conditioning Engineers) recommends the following strategies of interest to address disease transmission: dilution ventilation, laminar and other in-room flow regimes, differential room pressurization, personalized ventilation, source capture ventilation, filtration (central or unitary), and UVGI (upper room, in-room, and in the air-stream).
Coronavirus is highly susceptible to germicidal UV irradiation. The table below shows that the susceptibility of Coronavirus to UV is greater than 3 times as compared to the influenza (common cold) virus.
UVGI Solution is a proven method for removing volatile organic compounds (VOCs) and for killing or deactivating bacteria, viruses, mould, spores, and other pathogenic microorganisms that may be present in room air. it is now a well-known fact that UV is an effective disinfection technology, and can even kill the novel Coronavirus, responsible for COVID-19. With expertise spanning 2 decades, Alfaa UV’s UVGI air disinfection for HVAC systems offer the much-needed protection to stop the spread of bacterial and viral infections.
The UVGI system is not only cost-effective but also eco-friendly. Plus, when it comes to eradicating airborne viruses, it is considered a safe solution that provides you with a germ-free environment.
Alfaa UV’s Ultra Coil and Ultra Duct UVGI systems use world-class UVC lamps and unmatched Reflector Technology with UL Certification to ensure that all air passing through the system is disinfected as it re-circulates in indoor spaces. The design ensures 100% exposure of the air to the UVC system. The UltraCoil UVGI system not only fights viruses to create safer spaces, but it also ensures cleaner cooling coils, resulting in greater efficiency and lower running and maintenance costs.
Due to humidity and hospitable environment microorganisms grows rapidly on cooling coils. These microorganisms produce sticky substances due to which a thick layer of dust sticks to the coil which results into poor heat transfer between coil and air. Poor heat transfer between coil and air leads to greater energy consumption.
Installing a proper UVGI system in front of the coil kills such microorganisms, and hence it does not allow a biofilm to grow. A clean coil decreases the pressure drop across coil which results into the following:
Airborne transmission of diseases through HVAC systems is actually much more prevalent than previously thought. Hospital acquired infections are costing healthcare providers Lakhs of Rupees per annum and whilst robust cleaning regimes have been adopted, the spread of Tuberculosis, Meningitis, MRSA, Clostridium difficile, Chickenpox, and Influenza (H1N1 and avian), including Aspergillus and Pseudomonas continue to grow. These infections affect between 10 and 20% of patients and in some cases are fatal.
Airborne contamination comes from a variety of sources and circulates through the HVAC system.
Looking for a room sanitizer machine? Here’s presenting STERO-360, which is a new line of specialized UV Sterilizer machines that can eliminate more than 99.99% of bacteria and viruses on contaminated surfaces within minutes.
STERO-360 UV sterilizer lamp device is highly efficient due to its mobility and compact size. Moreover, with its strong Power cords and internals, it has the capacity to run all day continuously. Only protective goggles, glass shields, and PPE are required to operate this portable UV room sterilizer or else it can run on its own and can be scheduled & set up with a timer.
UltraHVAC UVGI Systems are highly effective as they can eliminate up to 99.9% of viruses and kill up to 90% of certain airborne bacteria that pass through the air, thereby offering complete air sanitization.
Greatly improves Indoor Air Quality (IAQ) and cures “Sick Building Syndrome” by destroying harmful airborne contaminants such as bacteria, viruses, mould, fungi and Coronaviruses.
By killing microbes and improving air quality, UV air disinfection systems can help boost productivity and reduce illness-related absenteeism.
Reduces or eliminates unpleasant odours that may result from outside air or re-circulated air within the building.
Air disinfection with UVC helps to maintain a clean evaporator coil, thus saving time and resources on coil cleaning. Using MERV filters in conjunction with in-duct UV systems can reduce the need for HEPA. This, in turn, can help enhance system efficiency and airflow.

UltraCoil and UltraDuct UVGI systems destroy high levels of airborne contaminants, including COVID-19 and surface bio-contaminants. Infections Acquired in Hospitals (HAI) can be a significant cost for the healthcare industry and is considered a preventable injury. Ultra UVGI IAQ systems are the ideal tool to help reduce nosocomial infections.
Air quality and reducing the risk of surface contamination is important in the production & packaging of food products. UV Sterilization of both air and/or surfaces of product and packaging by UltraHVAC UVGI systems can dramatically reduce the possibility of contamination. In fruit/vegetable markets, it can extend the life of the produce by destroying the off-gassing (i.e. ethylene) which causes faster ageing.
UV air disinfection systems help hotels and food retail chains to effortlessly meet the stringent disinfection and sanitization protocols required to ensure the safety of all customers within the premises. It is also an economical solution for these industries as it helps them save on energy as well as maintenance costs.
Maintain a safe and comfortable indoor air quality in shopping malls and retail chains with UV for HVAC systems and reduce the potential transmission of COVID-19 within the building environment. It can also help limit the spread of other air contaminants that cause infectious & inflammatory diseases, thereby improving the customers’ shopping experience.
A WHO report suggested up to 30% of new and remodelled buildings worldwide may be subjected to complaints related to poor indoor air quality, the leading cause of “Sick Building Syndrome.” According to the EPA, poor indoor air quality can directly affect the health of students, staff, employees, which in turn affect attendance and performance. Using UltraHVAC UV systems significantly improves air quality resulting in lower absenteeism and higher efficiency.
UVGI systems offer pharmaceutical and healthcare industry protection from harmful pathogens by deactivating airborne infectious agents. It helps curb infectious outbreaks and protects the health of building occupants. It is also effective in providing optimal protection for all processes from production to packaging.
