Wine Guardian TTW04B Sentinel Through-The-Wall Wine Cellar Cooling Unit

Yes. A built-in sensor combines thermostat and humidistat functions, and paired with an optional Wine Guardian freestanding humidifier it helps hold roughly 55% to 65% relative humidity, the band that supports long-term aging.

It delivers a nominal 3,760 BTU/h at 75°F (range 2,350 to 4,270), the largest model in the through-the-wall line, sized for larger residential and commercial cellars. Because cooling load also depends on insulation, glass area, and room temperature, confirm capacity with Wine Guardian's sizing calculator and a qualified professional.

The TTW04B Sentinel runs at about 57.9 dB measured at six feet, helped by its sound-reduction foam. That keeps cellar noise reasonable for the largest through-the-wall unit while it manages both temperature and humidity.

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

Both share the same 3,760 BTU/h cooling capacity, but the Sentinel adds a humidity sensor, an internal condensate evaporator, and sound-reduction foam. The Classic is the value, temperature-only option. Choose Sentinel for integrated temperature and humidity control.

Cubic footage alone will not size a unit. Insulation, glass area, room temperature, door sealing, and lighting heat all move the cooling load, and the Sentinel is rated for larger rooms. Confirm the exact capacity with Wine Guardian's sizing calculator and a qualified professional before ordering.

The Sentinel includes onboard Bluetooth and NFC controls, so you can read and adjust cellar temperature and humidity from the unit face or a smart device without a separate wired panel."]
