Why UV-C for COVID-19?

With the appearance of COVID-19, the need to implement disinfection processes in all areas has become prevalent, and public transport is fully affected.

There are different options, but unlike chemical disinfection methods, Type C UV light provides rapid and efficient inactivation of microorganisms through a physical process – when bacteria or viruses are exposed to the germicidal wavelengths of light. UV, their genetic makeup is altered so that they become unable to reproduce and infect.

A unique characteristic of UV light is its environmentally friendly character, without chemicals and very effective in disinfecting air and surfaces.

The efficacy of UV light is widely studied and used in a hospital setting, which has been the main recipient of this type of treatment to date, and from which knowledge and experience for the fight against CoVid-19 in other settings is extrapolated, Therefore, there are numerous publications on its efficacy (1).

BLED takes advantage of its telematic system for efficient and safe driving, incorporating UV-C disinfection as a managed service for interested operators. And it does so with the rigor provided by the partner and collaborator EuroLab, reference laboratories for the application of these systems in hospital settings.

UVC technology is currently already being used by various reference bus operators, such as the MTA in New York or other operators in China.

Safety comes first

Perimeter security elements for passenger protection. Disinfection level certification by independent laboratory. Security protocols and coordination with operations and communication to travelers included in the service.


With a basic configuration, you can guarantee a significantly high percentage of light exposure to the vehicle. The impact of residual shaded areas on the surface is minimized with the effective disinfection effect of the air that UVC achieves.


Effectively and automatically audits interventions and degree of disinfection of coverage areas. Scheduled interventions at headwaters, service points or at certain events (after using the toilet) to achieve a higher frequency of disinfection during the day.

Increased productivity

Elimination of manual processes and consumables (misting). Minimum maintenance once installed. High return on investment in the medium term compared to other systems.

Technical characteristics

TUSSAM buses
The first demonstrators begin in the Public Transport of Seville (TUSSAM).
