Heat Disinfect Reverse Osmosis (MediQA)

AmeriWater’s MediQA Heat Disinfect Reverse Osmosis System use proven reverse osmosis technology to provides a superior blend of reliability, efficiency and patient safety. When coupled with pre-treatment, this fully integrated water purification solution provides a complete system for 6 to 40 stations. Systems with single or dual pass membranes are available. With automated heat disinfection of RO membranes, MediQA units ensure that any potential for bacterial growth on membrane surfaces is minimized. User-friendly operation is managed through a full color touch screen display with comprehensive menu navigation – including full schematics. Password protected stored data includes active status indicators, alarm conditions and performance logs. The stored data can be downloaded to a remote PC or accessed through the touch screen.

The MediQA Heat Disinfect RO can be combined with the AmeriWater Heatsan Heat Disinfect System for the Distribution Loop for a complete heat disinfect system (RO and Loop).
