Key Features Built for the Most Demanding Conditions Feature What it means for your cellar Whisper-Quiet + Ultra Quiet Package Runs as low as 47.9 dB at 6 feet, the quietest unit in the Through-the-Wall line, so it stays unobtrusive in living spaces and tasting rooms. Precise Temperature Control Holds cellar temperatures from 42°F to 75°F with minimal swings, protecting wine from the fluctuations that cause premature aging. Humidity Sensor A combined thermostat and humidistat lets you connect a Wine Guardian humidifier to keep corks supple and labels intact. Condensate Evaporator An internal re-evaporation system manages condensate and usually removes the need for a dedicated drain line. Exterior Wall Package A coated condenser coil rated for 0°F to 125°F ambient lets the unit exhaust through an exterior wall, garage, or attic. Electric Heater A built-in heating coil warms the cellar when the room drops below your set point, holding conditions in cold climates. Triple fail-safe protection: a condensate overflow switch, a loss-of-charge switch, and an auto-reset high-pressure switch help prevent water damage, protect the compressor, and reduce system downtime.

Confirm the correct capacity with Wine Guardian's sizing calculator and a qualified HVAC professional before purchase. How do I install the Wine Guardian TTW01B Defender?
