Adding UVC to Your System Can Increase IAQ

UVC light has a lasting impact on disinfecting the air in your buildings.  It has high success in eliminating bacteria, viruses, and mold at rates upwards of 99 percent.  This technology can be implemented in your HVAC system so that indoor air is as clean as possible.

What is Ultraviolet Light

UV (Ultraviolet) light is a form of energy that is produced by the sun. UV is on the light spectrum, just below visible light. It is divided into four types: UVV, UVC, UVB, and UVA.

Ultraviolet C

Ultraviolet C Lightwaves

UVC energy at 253.7 nm provides the most significant germicidal effect. High Energy UVC exposure deactivates microbial organisms such as bacteria and viruses by altering the structure and their DNA. The organism’s ability to reproduce ceases, and it is then unable to colonize. Finally, the organism dies off, leaving no offspring, and the population diminishes rapidly.

Biofilm Presents a ChallengeBacteria HVAC before High Energy UVC

Biofilm is a complex microbial colony of mold and bacteria that sticks to coil fins and protects the organisms from biocides. This substance is a gluey matrix that grows on evaporator coils, drain pans, and ducts, within an HVAC system. The biofilm gives off volatile organic compounds (VOCs), which cause head­aches, watery eyes, allergy, and asthma responses. High Energy UVC destroys surface biofilm and airborne microorganisms before they can circulate through the HVAC system.

The Effect of Biological Contaminants on HVAC Systems

HVAC systems can harbor bacteria and mold. This can affect occupant health and development, resulting in reduced productivity and increased absenteeism. Biological contaminants commonly found on HVAC coils and drain pans can cause Sick Building Syndrome (SBS) and many other issues.

Steril-Aire Eliminates Contaminants

Steril-Aire products provide an average of 6 times the output of other ultraviolet devices under HVAC operating conditions. A full array of sizes and configurations are available to fit the broadest range of applications. Independent test results showed a 99.96% destruction in a single pass on airborne bacteria, 99% on viruses, and 96% on spores. Steril-Aire’s High Energy UVC products also do not create any ozone.

Maintenance and Energy Savings

Maintenance can be a significant expense, due to the difficulty and time required. Manual cleaning temporarily removes contaminants and can push contaminants further back into the fins. In contrast, Steril-Aire’s UVC options solve this challenge by eliminating the need for chemical cleaning of coils. It also minimizes system downtime for maintenance. UVC systems can restore older HVAC systems to efficient operation and maintain new systems by protecting against corrosion.

Applications Ideal for High Energy UVC

Over 14 million missed school days each year further drives the need to provide the best IAQ in schools as an essential objective. Indoor air pollution and the health, performance, productivity, and the comfort of students, teachers, and staff is a well-documented link. Airports are also a great candidate for adding UVC. They pose unique challenges with their confined spaces, as well as the constant hustle and bustle. Finally, UVC systems are also an excellent addition in hotels, gyms, laboratories, and office buildings.

Incorporating High Energy UVC into Your Facility

As the “respiratory system” of your building, the HVAC system must be clean and in excellent operational condition to provide optimal IAQ. Many studies have shown that the HVAC system is a transportation pathway of bacteria, viruses, and mold. Steril-Aire’s multi-patented UVC keeps coils and drain pans clean, eliminating the source of allergens, toxins, and irritants supporting a safe environment in both new and retrofit applications. By removing a viable breeding ground for bacteria, viruses, and other contaminants, circulated air will be significantly safer to breathe.
