WRO 300 H Dialysis RO System

    Portable Dialysis Water System

    The first 510(k) Portable Reverse Osmosis System with Automated Hot Water Disinfection. The WRO 300 H has been designed to overcome the problem of microbiological build up in portable dialysis water systems that may have extended idle periods. By integrating an automated heat disinfection system into the unit, the WRO 300 H system is engineered and manufactured to be clean by design.
