Model IonO2x - Odor Elimination Systems


IonO2x Odor Elimination Systems is a patented, true Non-Thermal Plasma (NTP) Technology that provides proven odor elimination of offensive organic odors. IonO2x Odor Elimination Systems can treat humid or dry process exhaust gases for any volume of air (single-unit systems for up to 60,000 CFM, and multiple systems for greater than 60,000 CFM).

IonO2x NTP technology relies on planar, dielectric barrier, high voltage electrodes, spaced with a narrow gap between ground electrodes. The electrodes are connected to a rapidly pulsing, high voltage power supply. This produces a rapidly reversing, high intensity electrical flux within the electrode air gap. The contaminated gas stream, requiring odor elimination, is passed through the electrode gap. The high intensity electric flux density fractures volatile organic compound (VOC) molecules and strips and heats, to extremely high temperatures, very low mass electrons. Large volumes of micro discharge streamers (essentially miniature lightning bolts, which produce a violet glow) are created. When the discharge streamers collide with diatomic oxygen and water vapour molecules in the gas stream, highly reactive oxidative radicals, known as Reactive Oxygen Species (ROS) and Hydroxyl radicals (OH radicals) are formed. An extremely reactive mixture of ionized gas and very high temperature electrons, described in scientific terms as 'Non-Thermal Plasma' or 'NTP', is produced.

Within the non-thermal-plasma, ROS, OH and free electrons instantaneously react with the fractured VOC molecules, with the predominant end products being water vapor and carbon dioxide. The key advantage of this method of odor elimination (or VOC oxidation), is that it allows oxidation reactions that would otherwise only occur at high temperatures of >1350 degrees Fahrenheit (or 730 degrees Celsius), to proceed rapidly, with very little measurable heat rise. Since there is little sensible heat rise of the treated gas stream, NTP oxidation technology is very energy efficient.

IonO2x systems are 'true' implementations of NTP oxidation technology. Free high temperature electrons, ROS and OH radicals have a very short half-life and cannot be injected in reactively significant volumes, even over very short distances. So called 'NTP' or 'Plasma Injectors' can only inject long lived, lower oxidation potential radicals, such as ozone. These systems can be accurately described as 'ambient air fed ozone injectors'. Ozone injection is very old technology (first used in the late 1800s). At best, ozone injection can achieve odor reduction of 25% to 35%. 'NTP or Plasma Injectors' are designed to produce large volumes of concentrated ozone, which is the opposite of true NTP technology, in which the goal is to minimize the production of residual ozone. True NTP odor elimination systems always require passing 100% of the contaminated gas stream through the electrode gap. Any system that does not pass 100% of the contaminated gas through the electrodes is not NTP technology.

Only extensively field tested and high quality, reliable, components are used in IonO2x equipment

IonO2x systems include a PLC based control system, with an operator interface touch screen, and a Plasma Generation Cell cabinet, which contains all of the system high voltage components. All IonO2x systems include a Category II electrical safety interlock switch and retained key interlock system to prevent the PGC cabinet from being opened unless the system power is turned off, thus ensuring operator safety. Only extensively field tested and high quality, reliable, components are used in IonO2x equipment. With simple, routine maintenance, IonO2x systems will provide many years of trouble-free operation.

IonO2x Odor Elimination Systems employ patented technology (US Patent numbers 6,991,768,7,767,167, and 8,475,723). Of key significance is that IonO2x Systems utilize hermetically-sealed high voltage electrodes, preventing electrical arcing, which is a common problem in other industrial scale, NTP systems.
