My old (1980s) fermentation refrigerator passed on this week. I am going to invest in a new Chest Freezer fermentation chamber and I am looking for recommendations. While my old refrigerator could precariously balance two 6.5 gallon fermenters I am hoping the new freezer will handle (3) 6.5 gallon fermenters. Dose anyone have a recommendation? I am currently looking at the Sears freezers but open to suggestion on size. Should I purchase two 7 cubic foot units or one 16 cubic foot unit. I have lots of room and power circuits will not be a problem. Pictures welcome (I have seen a couple of nice units on this forum already).
