How does UVC light clean an air handling unit?

It’s a year since we launched Gibbons Ultraviolet Solutions, a groundbreaking division offering ultraviolet-C (UVC) light products to clean and disinfect air handling equipment, ductwork and more. This revolutionary chemical-free technology has been installed in offices, hospitals, colleges and other non-domestic buildings across the world, but how exactly does it work?

UVC light has been used since the late 19th century and was instrumental in the control of tuberculosis (TB) in the 1950s. More recently it has been used to remove contaminants from HVAC systems in order to improve and protect the health and wellbeing of building occupants.

We’ve got a brilliant infographic that shows step by step exactly how UVC light eradicates mould, bacteria, viruses and volatile organic compounds (VOCs) from AHU surfaces and the air stream.

Take a look below:

As you can see, UVC systems can be used to destroy contaminants at both the cooling coil and within ductwork. Gibbons Ultraviolet Solutions has dedicated systems for both of these stages – CoilCare® and InDuct®, with these products offering quick and easy installation, low maintenance and energy savings of up to 25 per cent resulting from improved AHU performance.

With an increasing number of column inches being devoted to the issue of indoor air quality (IAQ), building designers and facilities managers are now realising the benefits of UVC technology for air handling equipment.

These systems represent the future of HVAC cleaning, so for more information about Gibbons Ultraviolet Solutions, call Colin Hardman on 07940 544206 or email
