Disinfecting Services

Public and crowded workspaces remain especially vulnerable to a rapid virus spread, so organizations are responsible for providing a more safe and secure environment.  UV-C is a scientifically proven technology that inactivates the ability of virus to infect and reproduce.

Private properties can be disinfected easily and quickly after the routine cleaning or maybe private functions utilizing the same UV-C technology.

Why UV-C Deactivates Viruses?

UV-C is an electromagnetic radiation that destroys the ability of microorganisms to reproduce by causing photochemical changes in nucleic acids. Wavelengths in the UV-C range are especially damaging to cells because they are absorbed by nucleic acids, disabling their ability to perform vital cellular functions. The germicidal effectiveness of UV-C peaks at about 250–265 nm, this corresponds to the UV absorption by bacterial DNA. The germicidal effectiveness of UV-C radiation can vary between pathogens, and the broader range wavelengths that include UV-B also make a small contribution to inactivation (Webb and Tuveson 1982).

UV-C radiation has been proven as an effective disinfection method for 80 years now.

Disinfection times for SARS-CoV-2

It is expected that fluence for the SARS-CoV-2 virus to be similar to any other enveloped coronavirus.

According several susceptibility studies, it is proven the right dose to disinfect 90% of coronaviruses ranges from 6 mJ/cm2 (mili-Joule per square cm) to 24 mJ/cm2 . To be on the safe side, we assume 25 mJ/cm2 as expected fluence to kill 90% (Log Factor 1) of SARS-CoV-2 in surfaces.

To achieve 99% (Log Factor 2) average increase of fluence for most of the known coronaviruses is 100%, so it is considered 50 mJ/cm2 as the minimum dosage to deactivate 99% of SARS-CoV-2.

Log Factor 3, this is, 99,9% reduction would recommend exposing the virus to 75 mJ/cm2.

Safety Standards


This International Standard specifies minimum human safety requirements for the use of UVC lamp devices. It is applicable to in-duct UVC systems, upper-air in room UVC systems, portable in-room disinfection UVC devices, and any other UVC devices which may cause UVC exposure to humans. It is not applicable to UVC products used for water disinfection.

Maximum daily dose per person is set in 6 mJ/cm2. SpeedyCare UV robot includes a set of safety features, including motion sensors which ensure an immediate switch-off to prevent the operator from UV-C exposure. However, in case of direct exposure to UV-C and according this standard, any operator could be safely exposed every day to 1 min at a distance of 4 m from the device.

Despite of the evident low risk of exposure, we recommend the use protective clothing and goggles, typically used for occupational safety and health purposes.
