The Wine-Mate 1500SSL cooling unit is a split system design with a cooling capacity of 150 cubic feet or approximately 800 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.
