Wine Guardian PRO SP88, a low-temperature Wine Cooling Units for midsize to large specialty storage applications such as fur storage, wine rooms, and other niche environments. It is a perfectly-paired condensing unit and evaporator section that comes standard with features such as electric heat, Extreme low ambient protection, and high ambient protection.

These Wine Cooling Units have a max capacity of 10,760 BTU/H. The SP88 is compatible with modern smart thermostats and features enhanced refrigeration controls. Wine Cellar Refrigeration Split System is the most versatile specialty cooling systems on the market. Applications include wine cellars, art or document preservation, instrument or fur storage, computer closets, niche environments, and more; these units can be used in nearly any application.

BTU/H Rating


The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.)

That do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.
