The Wine-Mate 2500SSL cooling unit is a split system design with a cooling capacity of 250 cubic feet or approximately 1200 bottles. With this split system, the condensing unit can be placed up to 50 feet away, and the cold air is fed into the cabinet or room via the fan coil. This allows for quiet unit operation while maintaining the proper storage temperature for your wine. This unit is significantly quieter than its predecessors of the SS series.
