Through-the-Wall Wine Cellar Cooling Units

It’s time to get serious about your fine wine collection. Wine Guardian Through-the-Wall (TTW) wine cellar cooling units bring exceptional airflow and optimal temperature control to ensure you enjoy 100% of the flavors of your wine.

TTW units match maximum efficiency with quiet operation to create peak wine storage conditions for your small- to mid-sized wine room or wine wall.

Designed for the Do-It-Yourselfer


The EasyMount™ one-piece wall bracket makes installation possible for any wine aficionado. Just insert the TTW into your cellar wall, make your drain connection, and plug it in. It’s really that simple to get set up and start enjoying your wine.

Sleek and modern.
Just like your cellar.


The TTW’s stylized air vents, bold silver faceplate, curved edges, and sleek touchscreen controls were designed to seamlessly integrate into the unique style of the modern wine cellar. These systems are engineered to look beautiful – and stay beautiful. Commercial-grade, corrosion resistant components and an all-aluminum frame keep the TTW unit looking good as it ages alongside your wine collection.

Complete Cellar Control


With a built-in thermostat, Wine Guardian lets you monitor temperature and humidity and control temperature right at the face of the TTW unit. Want to control and monitor the conditions while in your kitchen or den? Not a problem. Thanks to Wireless2Base™ technology, an additional controller and sensors can connect to your TTW anywhere in your home — so you can control your wine cellar wherever is most convenient to you.

Pairs well with a humidifier


A properly humidified wine space ensures the ultimate preservation and enjoyment of wine. As with improper temperature conditions, uncontrolled humidity can have devastating effects on wine like mold, loss of liquid, and dried out corks — just to name a few. Wine Guardian TTW units can be paired alongside a Wine Guardian Humidifier to create an environment perfectly curated for wine storage.

I have been using Wine Guardian's products since 2007. They have been my most reliable cooling system to date. Service and maintenance of the unit is very simple and only takes about 15 minutes. I would recommend these producers to anyone looking for a great wine cellar cooling unit.
