The purpose of Wine Cellar Cooling Units is to maintain a constant temperature and humidity inside a properly built and insulated space. Wine Cellar Creations has a wide range of manufacturers with a huge selection of configurations to fit any situation and budget. We carry self contained "through the wall" type units that are meant to vent cold air into the wine cellar and warm (not hot) air into another room. Compact wine cabinet units that are generally replacements for existing units. Ductless "split systems" where the evaporator and condenser are separate. The evaporator can hang on the wall, be ceiling mounted or it can fit inside of wine racking and the condenser would be in another room or outdoors. A ducted "split system" is where the cold air is vented through duct work into the wine cellar from another room and the condenser can be indoor or outdoor. There also self contained ducted units that can duct the cold air and warm air to different locations.
