AT MicroProtect

Pioneering Technology, Scientifically Validated

to Fight against Covid-19

The Techonology

AT MicroProtect technology

The AT MicroProtect technology has been developed by a multidisciplinary scientific team, ranging from engineering to physics, microbiology, virology and health sciences.

It is a worldwide pioneering technology with real scientific validation with viruses and bacteria, in particular SARS-CoV-2, the virus behind the COVID 19 pandemic. SARS-CoV-2, the virus behind the COVID 19 pandemic.

Microbiological protection barrier

AT Microprotect atua ao nível da proteção microbiológica, quer em ambientes fechados, como no interior de edifícios, espaços confinados e transportes de pessoas, atingindo resultados de inativação de vírus e bactérias com eficácia superior a 99% em 30 segundos. Atua de forma rápida, eficaz, focando-se em vírus ou bactérias, sem colocar em risco a segurança das pessoas. It is a quick, effective and affordable technology that does not compromise public safety.

Deployed locations

It could potentially be used in hospitals, schools, industrial units, public spaces and transport, such as airports and shopping centres, buses, airplanes, train carriages and subways.

This technology was designed to protect the interaction between people, in closed environments.

Scientific principles

The scientific principles of the technology are based on the use of (1) fluid mechanics and (2) UV emission systems, without compromising public safety and health. Combined, the two principles confer this technology the ability to adapt to different scenarios, as to be prepared not only for the current Covid 19 pandemic, as well as future pandemics and other public health issues, caused by multi-resistant bacteria and other viruses.

Technical and Scientific Innovations:

Mathematical calculation algorithm for the use of air as a protection system against viruses, bacteria and other microorganisms;

- Physical behaviour model for the inactivation of viruses, bacteria and other microorganisms using UV light (including control and automation of the UV system);

Increasing UV use efficiency without compromising people's safety and health.

Technological principles

The technological principles developed allow to improve the quality and safety of people inside buildings, without sacrificing thermal comfort originated by air renewal system or by the opening of windows and doors, thus ensuring the energy efficiency levels of the building.

Virus Transmission

The issue of easy dispersion of virus particles and other very small microorganisms

The SARS-Cov-2 virus, like other viruses and microorganisms that cause serious health problems, cannot be seen or felt.

Food flavourings serve as an example of how easily nanoparticles can propagate through the air.

When released in an uncontrolled way, it is possible to understand how far these nanoparticles can travel through the airflow within a building or confined spaces.


"European Centre for Disease Prevention and Control"

Closed and confined spaces

The first analysis of the "European Centre for Disease Prevention and Control", one of the most important European monitoring and action entities against the Covid-19 pandemic, on the main causes of the spread of the SARS-CoV-2 virus, concludes

Unequivocally in a report that indoor air renewal and air conditioning systems contribute to the spread of the virus and other microorganisms

(Area of action of AT MicroProtect), sendo que estes sistemas não são só responsáveis pela propagação deste vírus como de outros microrganismos).

It is, therefore, vital to act on...

"Four axis of non-pharmaceutical interventions (NPIs) that should be taken into consideration when reducing the potential airborne transmission of SARS-CoV-2 in enclosed spaces:

  • Control of COVID-19 sources in enclosed spaces;
  • control engineering in mechanical ventilation (by HVAC systems, air conditioning and air renewal) and enclosed spaces with natural ventilation;
  • Administrative and behavioural control to protect people. "..

The AT MicroProtect technology covers 3 of the 4 interventions and recommendations mentioned by the European Centre.

Ozone as an air purifier

Statement from the National Health Service

Ozone has been used as an air purifier. Although it works physically, it endangers people's health.

This has prompted the National Health Service to issue the following statement:

"Ozone, whether pure or mixed with other chemicals, can be harmful to health. It can damage the eye and respiratory mucosa and, like other photochemical oxidants, penetrates the deep airways affecting the bronchi and lung alveoli".
