Why should you use UVGI in your AHU or Ductwork?

Under CIBSE part F if you have an AHU with a mixing section in it, you must install a UVGI system.

Key Features

There are several benefits to using ultraviolet germicidal irradiation (UVGI) in your ductwork or air handling unit (AHU).

Firstly, UVGI can help improve indoor air quality by reducing the levels of bacteria, viruses, and other microorganisms that can circulate through the ductwork or AHU. UVGI works by emitting UV-C light, which is capable of destroying the DNA and RNA of microorganisms, rendering them unable to reproduce or cause harm. By installing UVGI lamps in the ductwork or AHU, you can effectively sterilize the air that passes through the system, which can help reduce the risk of infectious diseases spreading.

Secondly, UVGI can help improve the efficiency and lifespan of your HVAC system. By eliminating the buildup of biofilms and other organic matter in the ductwork or AHU, UVGI can help improve airflow and reduce the workload on the system. This can lead to improved energy efficiency, lower maintenance costs, and an extended lifespan for your HVAC equipment.

Finally, UVGI can be a cost-effective solution for improving indoor air quality. Unlike other air purification technologies, such as air filters or electrostatic precipitators, UVGI requires minimal maintenance and has no recurring costs. Once installed, the UV lamps only need to be replaced every 1-2 years, making it a low-maintenance solution that can provide long-lasting benefits.

Overall, by using UVGI in your ductwork or AHU, you can improve indoor air quality, increase the efficiency and lifespan of your HVAC system, and provide a cost-effective solution for maintaining a healthy and comfortable indoor environment.
