    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 a 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.



    Split System - The Platinum Split 4000 is designed for up to 1000 cubic feet.

    Installation: The Platinum Split Cooling System must be installed by a licensed refrigeration technician. The Ducted Platinum Split System offers the option of installing the condenser unit inside or outdoors. The system's flexibility in regard to installation lets homebuilders easily integrate the cooling system.

      NEW 24V Thermostat Conversion Kit:

      Tap into the latest technology to manage and monitor your wine cellar environment with WhisperKOOL.

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

      Utilize the industry leading technology from major manufacturers to monitor the environment of your cellar. (see individual thermostat manufactures features and benefits for details.)

      • Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet or laptop.
      • Monitor temperature and humidity through smart phones.
      • Monitor run time and energy usage.
      • Set alarm notifications
      • View your cellar conditions from your cellular 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.
      •     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.*

      Cold Weather Start Kit:

      Introducing the Cold Weather Start Kit by WhisperKOOL. This kit was designed exclusively for our split-systems where the condensing unit will be installed in extremely cold environments. Our split systems are designed to be adaptable to almost any install, as the condensing unit can be located in a variety of locations such as a mechanical room, basement, back yard, or even a rooftop. Our split systems were designed to operate with the condensing unit exposed to temperatures between 20° F and 110° F. However, there are some areas in the country that may drop below 20° F. Due to these conditions WhisperKOOL designed the Cold Weather Start Kit. So, when the outside temperatures drop, the pressure in the system drops as well. This presents a challenge because our systems operate using a pump down cycle and a low pressure switch to turn the compressor on and off. However, when the temperature drops below 20° F the pressure in the system is too low to start the compressor. The use of an electronic bypass is needed to start the compressor and temperature controlled heaters installed on the receiver are needed to raise the pressure in the system to optimal levels. 

      The Cold Weather Start Kit will bypass the low pressure switch on startup and keep the pressure in the system high enough to operate correctly for environments as cold as -15° F. It is important that the cooling system stays operational during cold weather conditions, as heating the house using the central HVAC system will indirectly increase the temperature of the wine cellar. This kit will ensure that the cooling system will continue to operate efficiently in cold weather environments to maintain an optimal wine storage temperature.
