Wine Guardian Through-The-Wall TTW02B Defender
The Wine Guardian TTW02B Defender Series is a premium through-the-wall wine cellar cooling system designed for residential and light commercial wine cellars requiring dependable performance and exterior wall installation capability. Built with weather-resistant construction and advanced sound attenuation, the Defender Series provides quiet, efficient cooling while protecting your wine collection from changing environmental conditions.
The TTW02B Defender is engineered to maintain the precise temperature and humidity levels needed for proper wine storage, helping preserve the character, aroma, and aging potential of your collection. Its durable design makes it an excellent choice for installations where the cooling unit is exposed to outdoor conditions, including garages, basements, and other locations where exterior wall mounting is preferred.
With a maximum cooling capacity of 2,650 BTU/h, the TTW02B Defender is ideal for small to medium-sized wine cellars. The self-contained through-the-wall design simplifies installation and eliminates the need for complex ductwork, making it a practical solution for homeowners, wine collectors, restaurants, clubs, and hospitality applications.
The TTW02B Defender is a 60 Hz, Type B plug-in unit, the standard electrical configuration used throughout most of North America, including the United States and Canada. Optional features, including a heater, low ambient protection, serving temperature control, and freestanding humidifier, allow the system to be customized for specific cellar requirements and climate conditions.
Proper sizing is essential for maintaining consistent cellar conditions. Use our Wine Cellar Cooling Calculator to determine the correct cooling system for your space based on cellar dimensions, insulation, ambient temperatures, glass exposure, and other heat-load factors.
Wine Guardian’s patented through-the-wall (TTW) wine cellar cooling systems combine efficiency, performance, and quiet operation to consistently deliver peak wine storage conditions. Appropriate for small- to mid-sized wine cellars, these innovative units make it easier than ever to maintain and monitor temperature and humidity levels in your storage space thanks to their integrated Bluetooth®-compatible controller.
Our TTW wine cellar cooling systems feature the following:
BTU/h Rating
2,650
The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.
Ductless/Ducted: Ductless Notable Features: Heater, Bluetooth / NFC Controls, Noise Reduction, Extended Temperature Control Range, Exterior-Rated Condenser
Standard Options
Heater
Provides additional protection for wine cellars located in colder environments. The optional heater automatically activates when temperatures drop approximately 2–6°F below the selected set point, helping maintain stable cellar conditions and protect your wine collection during cold weather.
Low Ambient Protection
Helps protect the cooling system when operating in colder surroundings. Low Ambient Protection allows reliable performance when temperatures fall below 40°F (5°C), making it ideal for installations in garages, basements, and exterior wall applications.
Serving Temperature
Expands the temperature control range to 42°F–64°F (5°C–18°C), allowing the wine cellar to be used for both long-term storage and serving-temperature cooling. This option is ideal for wine cabinets, small wine rooms, restaurants, wine bars, clubs, and collectors who want the flexibility to adjust temperatures seasonally or store wines closer to serving temperature.
Available Option
Freestanding Humidifier
Maintains optimal humidity levels inside the wine space to support long-term wine preservation. Installed directly in the cellar, the Freestanding Humidifier helps protect cork integrity, wine quality, and labels while integrating with the Wine Guardian controller for automatic humidity management.
