Gibbons Ultraviolet Solutions: What is UVC?

Following the launch of Gibbons Ultraviolet Solutions, we’ve been inundated with enquiries about our innovative HVAC disinfection treatment. One of the most common questions we’ve been asked is: “What is UVC?” so read on for a simple explanation.

Ultraviolet radiation is divided into various subcategories depending on wavelength range in nanometres (nm). Ultraviolet C (UVC) has a wavelength range of 280-100 nm and is classed as short-wave radiation. This means that it is completely filtered out by the ozone layer and atmosphere and does not reach the Earth’s surface.

Although we are not affected naturally by UVC light, it can be artificially produced by using ultraviolet germicidal irradiation (UVGI) photonisers, similar to florescent tubes. UVC light has twice the power of UVA (long wave) and UVB (medium wave) and has for many years been used as a disinfectant due to its ability to break down mould, bacteria and viruses.

Gibbons Ultraviolet Solutions apply UVC light to the cooling coil of an air handling unit, destroying ‘biofilm’ which is caused by a build-up of contaminants. If left untreated, this biofilm can present a threat to the health and wellbeing of building occupants while reducing the HVAC system’s efficiency.

We’ve provided answers to many other frequently asked questions on our Gibbons Ultraviolet Solutions page, but if you’d like further information, please call Andrew Knight on 07850 204915 or email
