TTW04B Defender 4000 BTU Wine Cellar Cooling Unit

 • The Defender is the premium model in the TTW lineup, offering expanded features for demanding applications. With a cooling capacity of 4,000 BTU/h, it is ideal for larger residential or commercial wine cellars requiring ultimate performance, control, and flexibility.

This unit is also easy to install, and can be installed on your own without the support of a contractor.

Although the cooling units are rated for various size rooms, the thermal load may require a larger sized cooling unit. Thermal load may be affected by glass in the cellar, room positioning or other factors. Please let a Rosehill Wine Cellar rep make some suggestions for you if needed.

Wine Guardian Through-the-Wall cooling units offer excellent airflow for your wine cellar, which assists to maintain optimal temperature & humidity — all this with whisper-quiet operation.

With expanded temperature settings (42°F to 75°F), enhanced sound insulation, and an exterior wall package, it is the most versatile and feature-rich option in the TTW Series.
