The Wine-Mate 6500HZD-DE is a partially ductable version of our popular HZD stand alone cooling system. This cooling unit is designed to provide a stable temperature up to 50~65°F - perfect for long term wine storage. By upgrading the fan and ducting this unit, the main cooling system and control panel remain in your wine room, but your hot condenser exhaust air can be exhausted up to 25' feet away to another room or to the outside. The humidity range of the refrigerated space can be maintained within 50~75%.
