The field of study of our start-up is focused on the study of plasma physics which aims to produce equipments adapted to the 21st century standards.Our first production is the ozoner, which is used to clean and refresh the air.Functions of Ozoner: 1) Kills bacteria and viruses in surprising speed. 2) Has a strong penetrating effect on sanitizing and oxidizing everything. 3) It can do oxidizing chemistry. 4) Refreshes the air removing disgusting smells. 5) Ozoner clears the air from dust. 6) Ozone disappears in surprising speed leaving no danger on human life.PPT's ozoner's disinfection scale is 20m^3, refreshing scale is 4400m^3 and productivity is 2gr/hour.Our big advantage is price. Our ozoner cheaper more than 2-3 times.In Armenia PPT is the only start-up 'Company' that has started the production of the ozoner.
