A through-the-wall wine cooling system chills a closet, basement room or custom cellar rather than a single cabinet. It mounts in the wall, with the cold side facing the cellar and the warm side exhausting to an adjacent space, so the heat and noise stay outside the wine room.
The six units below are all aimed at that job. We have not used these systems ourselves, and we avoid figures we cannot confirm. The cellar needs proper insulation, a vapor barrier and a correctly sized unit, so check the current listing and the maker sizing guide for room volume, ducting and electrical needs before ordering.

Wine Cellar Cooling FAQ
What is a through-the-wall wine cooling system?
It is a cooling unit mounted in a wall between the wine room and a neighboring space, so heat and noise are kept out of the cellar.
Does the cellar need insulation?
Yes. Without proper insulation and a vapor barrier, the unit will struggle and costs will rise.
Can I install it myself?
Some people do, but electrical work and wall openings may need a professional. Check local rules.
