4400L RO System

    4400L RO System


    Cutomizable High Purity Water System

    2,800 to 11,000 GPD 

    The 4400L is designed to produce up to 8 US gpm (30 lpm) at 41°F (5°C) of pure water to a storage and delivery system that can pump up to 80 US gpm (303 lpm) of high quality water to various points of use. The color touch HMI view coupled with an industrial PLC provides a robust control system for operator ease of use.
