Le Cache Primer: What’s the difference between forced-air and cold-wall cooling systems?

You’ll generally find two types of compressor-based cooling systems used in wine cabinets and cellars. The two types of cooling systems are discussed below.

Forced-air cooling systems are self-enclosed units that typically are mounted at the top of the wine cellar. These units use powerful fans to blow air across cold surfaces, called evaporator coils, and into the wine cellar. One advantage of forced-air cooling units is that they are easy to remove, repair and/or replace because they are entirely self-enclosed inside the wine cellar. Another advantage of forced-air cooling systems is that they provide more even temperatures and less stratification inside the wine cellar. However, forced-air systems are louder than cold-wall cooling systems when the fans are “on”, because the fans play a major role in creating and maintaining even temperatures throughout the cellar.

Cold-wall cooling systems typically are fully-integrated into the construction of the wine cabinets, with compressors located at the bottom of the cabinet, and evaporator coils that run up and down the back of the cabinet. Instead of relying on fans to distribute cold air, cold-wall systems radiate their BTUs into the wine cellar, resulting in the quieter operation than forced-air cooling systems. However, cold-wall systems sometimes have difficulty maintaining even temperatures throughout the wine cellar, and sometimes strip too much moisture and humidity from the wine cellar environment. Another disadvantage of cold-wall systems is that, because they are integrated into the walls of the wine cellar, they cannot be swapped easily and therefore are expensive to repair.

All Le Cache wine cabinets feature ultra-quiet, vibration-free forced-air cooling systems from CellarPro Cooling Systems, one of the industry leaders in wine cellar refrigeration equipment. Each wine cabinet comes with a 5-year warranty on parts and labor for the cooling unit, which is the longest warranty in the industry.

CellarPro offers a choice of cooling units with every wine cabinet, and CellarPro’s 1800QTL wine cooling units are among the quietest forced-air cooling systems in the industry. If that’s still too loud, we offer a sound hood that will knock down the sounds by another 2-3 decibels.
