9. This system is not designed for concentrations exceeding 5 to 6 degrees Brix for the3-membraneunit(whichhasarecirculationpump)and4degreesBrixinbatchmodeforthe2-membraneunit(whichdoesnothavearecirculationpump).Concentrationcapacityvariesdependingontheconditionofthemembranes,thetemperatureandqualityofthesap,andtheoperatingpressure.
