Whisperkool Ducted Wine Cellar Cooling Systems can be Self-Contained or Split Cooling Systems. Typically they have more installation options & flexibility. Moreover, the Cooling Unit may be installed up to 25 ducted feet from the wine cellar. Besides this, the cool air flows to the wine cellar. Accordingly, the heat exhaust is ducted to the outside of the wine cellar. In addition to this, ducting is also a more aesthetic choice for wine collectors who do not want to see a cooling unit in the wine cellar. Lastly, Noise from the Cooling Unit will be reduced or eliminated, depending on the installation.
