The Extreme Series are through-the-wall wine cellar cooling units designed for simple installation.  The Extremes and the SC Series do not require an HVAC-R technician for installation.

Extreme ti: The difference in the Extreme ti and the Extreme tiR is the display controller (thermostat) is located on the front of the cooling unit.

BTU/H Rating


The BTU/h value is an estimated number based on many variables.  A heat load calculation is needed to estimate the BTU/h value for your wine cellar.

To calculate your BTU/h, you will need the wine cellar dimensions, building materials used, such as glass, concrete, etc., physical and geographical location of your wine cellar and insulation value of the wine cellar.

Contact Summit Wine Cellars to have a heat load calculation done for your wine cellar.  203.916.1664
