Manufacturing of air treatment plants for industry. We have based by our own construction of DBD catalyst reactors. Our main conception - science & technology for environmental protection. We were the first to combine the method of `cold plasma` and `non-thermal catalysis` to provide a synergistic effect: the transformation of gaseous substances into elementary compounds of CO2 and H2O at low energy costs. Only 1-3 watts of electricity per cubic meter of air, treats it from harmful, carcinogenic and toxic gases.
