Advanced Heterogeneous Photocatalytic Oxidation active purification technology. AHPO-ETCS


The exclusive ETCS® technology with advanced heterogeneous photocatalytic oxidation is currently the best active air and surface purification system available.

DUST FREE® cells are designed in the shape of a honeycomb with a special composition of various metals and UV light, generating a purifying plasma that effectively and safely eliminates up to 99.9% of bacteria, viruses, harmful pollutants and molds. on surfaces and in the air.

ETCS is one of the few companies in the international market and the only national company that endorses and certifies the effectiveness of each of its photocatalytic reactors  with external laboratory tests.

Our systems help to certify, through UNE-ISO/PAS 45005/2021, the management of health and safety in workplaces and public centers.

What does DUST FREE® technology generate?

DUST FREE® active technology generates Hydrogen Peroxide (H₂O₂), Hydroxyls (OH-), Hydroxyl Radicals (OH) and Superoxides (O2-) safely and ecologically using ambient water vapor, destroying contaminants at the source of the problem, air and surfaces, and providing great benefits in the quality of indoor air.

Scientific tests, carried out by laboratories and different universities, demonstrate the effectiveness of advanced photocatalytic oxidation technology in reducing the bacterial and viral load.

Origin of Dust Free® technology


NASA, studying the physical process that occurs in nature, after a storm of strong electrical equipment in land areas with certain mineral compositions, verified the purifying effect produced in the air by the creation of certain purifying and ecological activators. This effect was considered as a Solar Gaseous Photocatalysis process.

Starting from this natural phenomenon, numerous laboratory studies were developed by the American Space Agency and its research centers as part of the Shuttle program and the International Space Station (ISS), to reduce polluting elements in the air inside the space.

What does Dust Free® technology consist of?

The innovative Triad Pure® advanced heterogeneous photocatalysis (advanced photocatalytic oxidation) purification technology is developed in the Dust Free® cell, composed of a high-density UV lamp housed within a catalyst designed in the shape of a honeycomb.

This high-tech catalyst is made of a patented noble metal alloy and coated with a hydrophilic material that captures ambient moisture. This design allows the reactions generated starting from water vapor (H20) to be clean, to occur more quickly and to strengthen the bond between the hydrogen and oxygen molecules, so that once the disinfectant molecule is in the air it lasts longer.

The energy provided by the photons of light in the catalyst reacts with the ambient water vapor and generates Hydrogen Peroxide (H₂O₂), Hydroxyls (OH-), Hydroxyl Radicals (OH) and Superoxides (O2-). These oxidants work in synergy creating a purifying plasma that actively removes up to 99.9% of viruses, bacteria, odours, smoke, pollen, dust, mold, mites, spores and volatile organic compounds from the air and surfaces.

After carrying out their purifying function, these compounds dissolve naturally, becoming harmless water (H2O) and carbon dioxide (CO2).

Dust Free® technology is currently the most advanced on the market and has been designed to obtain the maximum production of natural oxidants with a catalyst surface area between 6 and 8 times more compared to other systems.

What is Dust Free® technology for?

Dust Free® advanced purification technology generates a purifying plasma that performs 4 natural functions.

Disinfection. Thanks to the natural oxidants generated, such as hydrogen peroxide, up to 99.99% effectiveness is achieved in eliminating bacteria, viruses and germs, in addition to eliminating fungi and mold. It is an essential complement for air conditioning and ventilation installations with duct networks.

Ionization. Discharge of negative ions that modify the molecular structure of suspended particles, favoring their precipitation by gravity and eliminating them from the air we breathe.

Deodorization. Decomposition of gaseous molecules leaving the space free of smoke and unpleasant odours.

Oxygenation. With the action on the oxygen molecule.

Advantages of Triad  Pure®-Dust Free® technology

Thanks to its patented formula of catalyst with a combination of metals, hydrated coating and large exposed surface area, it is the only active technology that provides the solution to the problem of environmental pollution:

  • Eliminates up to 99.99% of viruses, bacteria, odors, smoke, pollen, dust, mold, mites, spores and volatile organic compounds, among others.

  • Does not generate ozone. You can work continuously 24/7 in spaces occupied by people or pets.

  • The only technology capable of regenerating oxygen.

  • Ecological. Low consumption and minimum maintenance.

  • Dramatically reduces contaminants immediately at the source.

  • High level air and surface decontamination.

  • Microbicidal and sporicidal activity.

  • Patented non-toxic breathing safe system.

  • No chemicals or carcinogens.

  • No by-products or toxic residues.

  • No downtime.

  • Easy to install.

  • Reduces sickness/absenteeism of employees.

  • Substantial odor reduction.

  • Disinfect air ducts. Reduction of periodic interventions for the maintenance of ventilation ducts.

  • Installation in ducts or portable units "Plug and Play".

Moisture Consideration

Dust Free requires at least 40% humidity to provide an adequate amount of hydrogen peroxide. If you live in a dry area, installing a humidifier is recommended to keep the humidity at an optimal level.
