Products Features/Specifications Resources

Versatile and self-contained, our ducted wine cooling systems offer maximum flexibility in design and installation. They also provide cooling for any sized area, whether you are storing in a residential, restaurant, or commercial wine cellar. With ducted wine conditioning systems, a grille on the inside wall is connected by insulated flexible ductwork to a self-contained unit outside the wine cellar that contains the evaporator, fans, compressor, condenser, and controls. This system can be placed in an indoor location outside the cellar resulting in a quiet cellar with no obtrusive equipment taking up valuable racking space. Ducted wine room systems are ideal for larger private or commercial wine cellars. Available in water-cooled configurations.

Make sure your expected duct runs will be compatible with your ducted unit by using our basic ductwork calculator.

Water-Cooled Configurations

Wine Guardian’s water-cooled units are ideal for geothermal, cooling tower, and lake water applications and offer unique control and operating features not found on competitor’s systems. Also, no warm condenser air connections are required so it could be a good solution when warm condenser air venting is an issue. Completely self-contained through-the-wall or remote systems provide optimal temperature and humidity control for the preservation and enjoyment of your wine investment. Available in four capacities producing between 3,760 BTU/H to 15,680 BTU/H, net output (880 to 3,812 watts).

Ducted, and ducted split systems, ceiling systems, and integrated humidifiers are sold and supported through an international distribution network. Contact one of Wine Guardian’s authorized distributors for assistance.
