Microzone Series

ClearWater Tech Microzone Series uses corona discharge (CD) technology to provide superior ozone performance in a compact size. A plug-and-play product line that delivers tremendous value with minimal complexity and cost.  The Microzone series family of ozone generators are easy to install and maintain. They are wall-mounted, require no air preparation, and are designed to operate in a wide range of environments.


The Microzone ozone generators may be used to inject or diffuse ozone into water.  The injection method requires a venturi injector to draw the ozone from the ozone generator and into the water line.  ClearWater Tech has developed the PRO Series System with magnetic drive pump, programmable timer, and venturi to provide a suitable suction port for the injection method.  For typical spa applications the spa manufacturer has provided an "ozone ready" suction port, which eliminates the need for additional equipment.

The diffusion method requires a pressurized air source, which feeds air through the ozone generator and out to an atmospheric body of water.  A diffuser stone provided with the Microzone ozone generator is used for increased mixing of ozone in solution.  For this application ClearWater Tech has developed the OAS7 compressor, with programmable timer to provide the pressure required.
