The mixed-bed polisher is used to ensure a low residual conductivity (< 0.2 µS/cm) and can be used downstream of a UP unit or also downstream of an ultrapure water pressure booster station. In the standard version, the two pressure tanks of the MB-Polisher are operated in parallel; with the optional expansion package, connection in series is also possible. The mixed-bed resin is not included and must be ordered separately.
