Wine Cooling Unit Components

Questions to ask when purchasing a cooling unit

Q
Which compressor is used in my cooling unit?
A
The most important component
The compressor is the engine inside the cooling unit, and the single most important component. The compressor must be sized to fit the footprint of the cooling unit, the volume of the cellar and the targeted temperature and humidity ranges. It must also be quiet, vibration-free and reliable.
CELLARPRO: High-output, brand-name compressor
CellarPro cooling systems use quality compressors from Danfoss, a global leader in refrigeration products based in Denmark. Our compressors are oversized to achieve better performance and longevity.
 
Q
Which fans are used in my cooling unit?
A
Fan noise can be disruptive
Fan noise is the primary sound that is emitted from wine cellar cooling units. Therefore, it is imperative that the fans are both quiet and, at the same time, powerful enough to minimize stratification inside the cellar AND create enough cooling power to operate effectively in warm environments.
CELLARPRO: Super-quiet, high-output fans
CellarPro uses fans that are designed to produce low noise emissions and high output airflow. By generating high airflow across both coils, CellarPro cooling units maximize cooling capacity and reduce temperature stratification inside the cellar. By sourcing specialized fans, we are able to keep the noise level of our CellarPro 1800QT cooling unit below 50 decibels when installed in a wine cellar, or the same as many refrigerators.
 
Q
How do the condenser and evaporator coils work?
A
Larger components dissipate more heat
Condenser coils are used to dissipate the heat generated by the refrigerant when it is compressed from gas into liquid, and therefore are located on the "outside" of the cellar.

Evaporator coils remove heat when warm air comes into contact with the cold surface of the coils. The coils are kept cold when the internal refrigerant expands inside the coils.

Coils should sized as big as possible within the constraints of the enclosure, the compressor and the fans. In addition, the evaporator coils should be coated to resist corrosion, which occurs when airborne pollutants come into contact with the coils. Left untreated, corrosion in the coils eventually will cause leaks and loss of refrigerant in the system, rendering the cooling unit incapable of removing heat from the cellar.
CELLARPRO: Oversized condenser and coated evaporator coils
Our evaporator coil is coated with AerisGuard, a high performance epoxy coating. The coil is dipped, not spray-painted, for a better coating, and then baked to provide a chemical-resistant barrier against corrosion.

Because we source the highest quality components, we are able to provide the best cooling unit warranty in the industry: 5 years parts and labor warranty coverage.
