A ducted system has more installation options than a self-contained system. 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.

Product Features

The Fully Ducted Extreme Series units can be positioned up to 25 ducted feet from the cellar, creating a noise-free cellar environment. Fully ducted installation provides many installation options, allowing you to not only put the unit in more remote areas of the home but to also have full control of where the exhaust air vents to. This series features an advanced liquid temperature controller with a remote LED display (which can be placed up to 300 line feet from the unit) and electronic thermostat. The systems are designed to maintain 55°F and 50-70% relative humidity.

The WhisperKOOL Platinum 4000 Fully Ducted Split System will cool a wine cellar up to 1000 cubic feet. For cellars up to 2000cubic feet, there is a larger WhisperKOOL Platinum 8000 (also available fully ducted). Key Features:

Product Description

"Virtual Silence"

The Fully Ducted Platinum Split is WhisperKool's newest model to the split line-up. Ducting a Split creates a virtually silent cellar environment and allows for maximum installation options. The system uses our liquid bottle probe for monitoring the actual temperature of the wine to ensure the wine is being kept at 55°F. The evaporator portion may be installed up to 25 duct feet from the cellar.

The WhisperKOOL Platinum series of split systems is the most efficient ever put out by WhisperKOOL. The WhisperKOOL Platinum 4000 Fully Ducted Split System is a completely new design that improves airflow efficiency by 25% while being 10% quieter and 35% smaller than previous WhisperKOOL split systems. The WhisperKOOL Platinum 4000 fully ducted cooling system uses the superb WhisperKOOL liquid bottle probe to monitor the actual temperature of the wine for more accurate cooling. The WhisperKOOL Platinum 4000 Fully Ducted system also features an advanced electronic control system, humidity control, an energy-saving mode, and alarm capabilities. For ease of installation, the WhisperKOOL Platinum 4000 Fully Ducted Split System offers flexible installation options and the choice to put your condenser outside with the optional housing. Please note that these systems do not include a line set.

The WhisperKOOL Platinum 4000 Fully Ducted Split System will cool a wine cellar up to 1000 cubic feet. For cellars up to 2000cubic feet, there is a larger WhisperKOOL Platinum 8000 (also available fully ducted).

  • Monitor temperature and humidity through smart phones.
  • Monitor run time and energy usage.
  • Set alarm notifications.

  • Nest
  • Ecobee
  • Honeywell


Not utilizing the thermostat from WhisperKOOL also eliminates the use of the bottle probe. WhisperKOOL does not provide SMART thermostats. Those must be purchased separately. WhisperKOOL customer service staff does not provide technical support for the customers selected thermostat.

**The 24-volt Thermostat conversion kit is currently available as an option for all Platinum and Ceiling Mount Split System models.**
