Wine Guardian’s ducted split wine cellar cooling system provides superb air distribution and temperature control for optimal conditioning of your wine cellar. The extremely quiet and virtually vibration-free system offers maximum flexibility in system location and cellar designs. Our system makes it ideal for cellars that have little or no extra space to install a self-contained Wine Guardian system, for applications where condenser air is difficult to exhaust and for longer duct runs. We offer four ducted split models that are available in four capacities producing between 3,400 to 14,900 BTU/H in 60Hz models and four ducted split models that produce between 1,055 to 3,812 watts in 50Hz versions. The split system operates in ambient temperatures between 0°F and 115°F (-18°C and 46°C). As with all Wine Guardian products, it is certified by ETL to UL and Canadian standards for safety and performance.
