The series use the oxygen which produce by the install Oxygen generator as a source. then get high concentration ozone. Features a) We apply adsorbing media from UOP in the U.S.A. By changing adsorbing pressure (PSA) oxygen generators split oxygen from nitrogen, filtrate out poisonous substance in air, then get high concentration oxygen which is up to medical standard. b) SOZ Series ozone generators use high reliability ,high efficiency and long life non-hydroxide crystal titanic generating cell, The cell is designed particularly with ozone resistant double pipes. They are cooled by air or cool water. SOZ Series use high quality components. Intelligent cell design is the first creation in the world.(patented) c) Adjust the ozone and low noise d) Easy to operator, product at any moment.
