COSMO Kleini

For Water Treatment and Sterilization - The Transition Made Possible

COSMO Kleini is a compact micro-plasma sterilization system suitable for a variety of industrial applications such as medical- and pharmaceutical- grade water sterilization, food safety applications such as agricultural product washing, cold storage and sterilization, drinking water disinfection, and more. Using a patented technology, Kleini utilizes atmospheric air to generate spatially uniform plasmas that improves energy efficiency and enhances stability by increasing electron density compared to the existing methods. This leads to the production of radicals that are lethal to a wide range of microorganisms, such as E. coli, Giardia and drug-resistant pathogens.

This cutting-edge low-temperature micro-plasma technology offers a very low footprint and ownership cost. Kleini is the perfect transition for disinfection, sterilization, and decontamination using an eco-friendly sustainable technology. It is a compact, air-cooled system that sets a new pathway in purification.


 Apart from its industrial applications, its biofilm deactivation properties and ability to significantly reduce concentrations of fecal indicators makes it ideal for point-of-use drinking water treatment purposes. It is widely used in various geographies in the United States, Europe, Asia and Africa (in low- and middle- sociodemographic regions) to provide clean potable water and improved sanitation. For example, in ‘real-world’ settings of a Kenyan village where source water had very high turbidity, concentrations of E. coli were reduced substantially.
