The Wine Rack Company is proud to be an authorized dealer for Wine Guardian, the premier commercial-grade wine cellar environmental control system manufacturer. Wine Guardian now offers both a remote ductable unit and a true split cooling system in 1/4 Ton to 2 Ton capacities as well as a through-the-wall cooling unit in 2 capacities.

Ductable Remote Cooling

Completely self-contained and infinitely flexible, ducted systems are among the most versatile cooling systems on the market. Their design allows for easy installation and maintenance in both commercial and residential settings while providing optimal temperature and humidity control. With a variety of capacities and options, ducted units are capable of meeting the needs of virtually any wine preservation application.

Split System

Wine Guardian’s ducted split system provides superb air distribution and temperature control for optimal conditioning of your valuable wine collection. The extremely quiet and virtually vibration-free system offers maximum flexibility in system location and cellar designs. This makes it ideal for cellars that have no space to install a self-contained WG system, for applications where condenser air is difficult to exhaust, and for longer duct runs. Four ducted split models are available—1/4 ton, ½ ton, 1-ton and 2-ton capacities.

The split system operates in ambient temperatures between 0°F and 115°F (-18°C and 46°C). And just like all Wine Guardian products, it is certified by ETL to UL and CSA standards for safety and performance.

Advantages of External Ducting

  • Lower sound levels
  • Virtually no vibration in the cellar
  • Better air distribution and temperature control
  • Flexibility of where to locate the unit
  • Ability to exhaust the excess heat and/or recapture and redirect for energy conservation
  • Greater flexibility in cellar design
  • Easier to service

WhisperKOOL is an industry leader in economical wine cooling. They offer an extensive line of cooling options including through-the-wall, remote and ducted units in a variety of sizes to suit any wine cellar project.

Self-Contained Units

These units are the most economical and easiest to install. They are designed to mount between the studs of an existing wall, and they do not require a licensed HVAC/R installation technician. One end of the system blows cool air in to the cellar, and the other end absorbs heat from the cellar and exhausts the heat into an area adjacent to the cellar. Self-contained units will make more noise than a split or ducted system.

Ducted Units

A ducted unit has more installation options than a self-contained unit. The unit may be installed up to 25 ducted feet from the cellar, with the cool air flowing to the cellar and the heat exhaust ducted to the outside of the home. Ducting is also a more aesthetic choice for wine collectors who do not want to see a cooling unit in the cellar. Noise from the unit will be reduced or eliminated, depending on the installation.

Split Systems

The Split System is often the most efficient way to cool a cellar. Cooling unit condensers are typically noisy and require significant space for ventilation, in most cases the cellar location does not include an area for these functions. By splitting the cooling system, the condenser can be placed in a space better suited for heat and noise dissipation while the quiet evaporator is inside, or near, the cellar. A licensed HVAC technician is required for the installation.
