Wine Guardian TTW02B Sentinel Through-The-Wall Wine Cellar Cooling Unit

The TTW02B Sentinel delivers a nominal 2,650 BTU/h at 75°F, sized for mid-sized residential and commercial wine cellars and displays. Because cooling load depends on insulation, glass exposure, and ambient temperature, confirm the right capacity with Wine Guardian's sizing calculator and a qualified professional before purchase.

Yes. The TTW02B Sentinel includes a built-in humidity sensor that combines a thermostat and humidistat. Paired with an optional Wine Guardian freestanding humidifier, it helps maintain roughly 55%-65% relative humidity for proper long-term wine storage.

The TTW02B Sentinel is designed for do-it-yourself installation between standard wall studs, using the included mounting bracket or a wall sleeve. It exhausts heat into an adjacent interior space and is not rated for exterior use. Final placement, electrical, and ventilation requirements should be confirmed with Wine Guardian's documentation and a licensed professional.

The TTW02B Sentinel operates at about 56.7 dBA, helped by its sound reduction foam. That keeps cellar noise low while the self-contained unit maintains temperature and humidity.

Both share the same 2,650 BTU/h cooling capacity, but the Sentinel adds a humidity sensor, an internal condensate evaporator, and sound reduction foam. The Classic is a value option without humidity control. Choose Sentinel for integrated temperature and humidity management.

The TTW02B Sentinel includes an internal condensate evaporator that re-evaporates condensate, which often removes the need for a dedicated drain line. Final drainage requirements should be confirmed with Wine Guardian's documentation and a qualified professional.
