Absolutely agree Steve. Having a refrigerated bulk tank essentially decouples the RO process from the evaporation process. You can let the RO run when the sap comes in, and then boil another time (assuming your tank is large enough). It is especially useful for those smallish runs that happen early and late (and sometimes in the middle) of the season. Normally if you RO you'd have to boil, but it might be for only 30-60 min and then shut down. With the bulk tank...you just save it until you've got enough to boil for 4-5 hrs. Where this really saves is on clean-up time. We never boil in the evenings or on weekends any more.
