UV light solutions to help in the fight against Coronavirus

UV light is a proven technology when it comes to reducing bacteria, viruses and other harmful microorganisms that pose a risk to human health. Ultraviolet (UV-C) light kills or inactivates microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

For many years, UV germicidal lamps have been used for disinfection of air and surfaces within hospitals, care homes, laboratories and many other organisations where hygiene and cleanliness are of utmost importance. In light of the current Coronavirus outbreak, UV is just one of the many technologies available and being utilised to help reduce and control the spread.

We offer a range of UVC disinfection lamps to help improve cleanliness and reduce the risk of cross-contamination

UVC Decontamination Trolley (600W)

Price: £19,995.00
Lead time: Approximately 4-6 weeks

Disinfect air and surfaces in unoccupied rooms. Effective from just 10 minutes exposure. Operated from outside the room via tablet (supplied) and includes motion sensor deactivation for safety.

UVC Germicidal Hand Lamp (400W)

Price: £2,495.00
Lead time: Approximately 8 weeks

Disinfect equipment and surfaces in unoccupied rooms in a matter of seconds. Allows disinfection of shadow areas that fixed mount lighting may not reach.

UVC Germicidal Unit (150W)

Price: £1,195.00
Lead time: Approximately 8 weeks

For fixed mount disinfection of air and surfaces in unoccupied rooms. 4m x 4m area when mounted at 2.5m height. Multiple units required for larger areas or to reduce shadowing.

More about UV-C light and Coronavirus

The following information has been published by ResearchGate.net regarding the susceptibility of Coronavirus to UV light.

“Table 1 above summarises the results of studies that have been performed on Coronaviruses under ultraviolet light exposure, with the specific species indicated in each case. The D90 value indicates the ultraviolet dose for 90% inactivation.

Although there is a wide range of variation in the D90 values, this is typical of laboratory studies on ultraviolet susceptibility. The range of D90 values for coronaviruses is 7-241 J/m2 the mean of which is 67 J/m2, should adequately represent the ultraviolet susceptibility of the SARS-CoV-2 (COVID-19) virus.”

By using this exposure data, and comparing the UV light irradiance measurements from our UV disinfection lamps and systems, we can easily calculate the exposure times required to achieve a particular log reduction based at specified distances from the source.
