Self Contained systems are designed to mount between the studs of an existing wall. One end of the system blows cool air in to the cellar, and the other end exhausts the heat from the cellar into an area adjacent to the cellar.
Split Systems “split” the cooling system in two, with the evaporator inside the cellar and the condenser being placed nearby. Placing the condenser in a remote location keeps the wine cellar quiet and vibration-free.
Ducted Split Systems split the cooling system in two, where the condenser can be placed in a space better suited for heat and noise dissipation and the evaporator is ducted nearby the cellar. This keeps the wine cellar quiet and vibration-free.
A Fully-Ducted Self Contained system may be installed up to 25 ducted feet from the cellar, with the cool air flowing to the cellar and the heat exhaust ducted to the outside of the home. Ducting is for wine collectors who do not want to see a cooling unit in the cellar or want noise to be reduced or eliminated.
