A high output UVC provides continuous cleaning of coils, eliminating biofilm and increasing efficiency.
What if there was an affordable, non-chemical method to provide continuous, non-chemical cleaning of ductwork and coils? UVC Emitters germicidal lamps help keep HVAC coils and drain pans clean, which, in turn, reduce energy consumption and improves indoor air quality (IAQ). And, the only required maintenance is to change the bulbs about once a year,
Numerous studies have shown that HVAC systems are full of of pathogenic and opportunistic bacteria and mold. If not dealt with properly, these pathogens can be circulated throughout your building via your ductwork.
How Does a UVC Emitter Work?
Ultraviolet (UV) light is a form of electromagnetic energy produced naturally by the sun. UVC refers to ultraviolet light with wavelengths between 200 – 280 nanometers (nm). UV light comes in between 100 and 200nm, UVB between 280 and 315nm, and between 315 and 400nm.
The entire UV spectrum has the ability to kill or inactivate microorganisms, but UVC light energy provides the most germicidal effect. UVC targets the DNA of microorganisms, destroying their cells and making replication impossible. By applying UVC at the primary sources of contamination – VAC evaporator coils and drain pans – you can drastically improve HVAC environmental hygiene and thus improve IAQ, as well as overall energy efficiency.
The Benefits of UVC Devices in Commercial HVAC Settings
- Optimize HVAC performance
- Reduce energy costs by up to 15%
- Cut maintenance costs
- Drastically improve indoor air quality (IAQ)
- Reduce water use
What is HVAC Biofilm and Health
Biofilm is an active, complex microbial matrix of mold and bacteria that adheres to HVAC evaporator coils, drain pans, and ducts, protecting the organisms from biocides. The biofilms themselves give off what are known as volatile organic compounds (VOCs), which can cause headaches, allergic reactions, and asthma responses among your tenants. So it is important for business owners and facility managers to reduce the presence VOCs. Unfortunately, manual cleaning can be time consuming and expensive, and coil cleaners, sprayers, and pressure washers only do so much as they penetrate just 1 inch into the coil. In order to fully deal with organic and biologically active matter, UVC is needed.
HVAC Biofilm and HVAC Efficiency
Buildup of HVAC biofilm can greatly diminish HVAC efficiency by increasing air flow resistance and decreasing heat transfer. As a result, fans need to run longer to maintain a desired temperature, and chillers and pumps need to work harder to achieve set temperature points. A high output UVC provides continuous cleaning of coils, eliminating biofilm and increasing efficiency. The removal of just .024” of biofilm can reduce HVAC energy usage by 21%.
