Puro™ RD Reverse Osmosis Water Purification System

Enjoy the benefits of Reverse Osmosis water with the feature-rich, compact, and scalable Puro™ RD from Avidity Science. The Puro RD Reverse Osmosis system removes contaminants from water detrimental to animal health, protecting them and minimizing unforeseen variables that could compromise vital research. The cabinet style unit provides easy access to the onboard RO membranes, filtration, distribution pump, chemical injection and an integrated high-definition touchscreen controller - all within a compact footprint.


The efficient, modular design of the Puro RD allows for increased RO water production as facility demand increases. Adding additional RO membranes can boost production to 200 liters (52 gallons) of purified water hourly. Product water can be stored in the 100-liter tank within the Puro RD unit, or in an external tank tailored to facility requirements.


The Puro RD makes optional post-treatment by chemical injection easy. It analyzes user designated setpoints, automatically mixing water and post-treatment chemicals to the desired ratio. Localized system alarming is displayed on the touchscreen and can be adapted into the building automation system by dry contact for general alarm notifications.
