The CSA SYSTEM S-TRAIN is a continuous sanitiser for integration into the air conditioning (HVAC) systems of trains, to maintain high levels of air healthiness for passengers and crew; the device provides protection from viruses, bacteria and moulds most commonly found in means of transport.
The patented technology reduces the presence of airborne microorganisms, achieving inactivation rates of over 93%*. In addition to ensuring indoor sanitation, the CSA SYSTEM purifies the air with percentages exceeding 92% by removing air pollutants such as particulate matter, dust. allergens and volatile organic compounds (e.g. formaldehyde).

Our devices combine continuous sanitisation and air purification in the presence of people to achieve maximum health benefits. This is possible thanks to our patented chemical-free and people-safe CSA SYSTEM technology.
In this type of means of transport, the air is mainly recycled, with a low percentage of renewal with external air, thus favouring an accumulation of pollutants inside the wagons, in the HVAC and in the ducts.
The study of sanitisation technologies and automation has allowed us to develop a line of products for automated surface sanitisation applied to each context.
Those carried out by STE and the University of Urbino Carlo Bo were the first tests performed in the field, in a train environment. Prior to our publication, in fact, no scientific data had been reported on sanitisation systems applied to the rail and tram sector.
We tested our CSA SYSTEM S-TRAIN on the medium-distance train (Vivalto). Through these tests, we obtained results that confirmed the need to install sanitisation systems on these vehicles, to guarantee healthy air inside the passenger compartments, protecting those inside the train.
Despite the fact that the concentration of micro-organisms used during the efficacy trials of the CSA SYSTEM S-TRAIN was significantly higher than that typically found inside a train, the device was able to achieve average microbial inactivation rates of over 93%.
