WhisperKOOL Fully Ducted Self-Contained Phantom 3500

When you are designing and building a custom wine cellar flexibility can make your like so much easier. Say hell to the WhisperKOOL Phantom 3500 Wine Cellar Cooling System.

The Phantom 3500 is the most flexible, fully ducted wine cellar cooling unit on the market.

The super intelligent design allows you to customize the blower configuration. The blowers can be independently reoriented to the right, left of top of the wine cooling unit. 

This means that you can install this unit with any ducting configuration you desire! How's that for flexibility. No more worrying about whether a cooling unit will fit into your space and design. 

The Phantom 3500 is your solution.

Owner Manuals & Tech Sheets

BTUh Rating


The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) which do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.

24V Thermostat Conversion Kit

Introducing our new 24-volt thermostat conversion kit for WhisperKOOL split systems!

Utilize industry-leading technology from major manufacturers to monitor the environment of your cellar. (See individual thermostat manufacturers’ websites for details.)

  • Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet or laptop.
  • Monitor run time and energy usage.
  • Set alarm notifications.
  • View your cellar conditions from your mobile device.

The use of the 24-volt thermostat conversion kit eliminates the thermostat normally included with the system and allows your contractor to select, purchase and install the thermostat technology of your choice, including but not limited to Nest, Ecobee, and Honeywell.

By selecting the 24V Thermostat Conversion Kit, you have acknowledged that the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. You will have to source and purchase your own 24V thermostat to run the equipment.

  • 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 do not provide technical support for customers’ selected thermostats.
  • Cellar Size: 800 cu. ft.* (Each wine cellar is unique and has specific cooling requirements. Heat load calculations should always be performed prior to selecting a cooling unit. See our Cellar Wizard.)
