WhisperKOOL Platinum Split Twin Ductless Cooling System Overview

When the wine cellar is fully insulated and sealed with a proper vapor barrier (each wine cellar is unique and has specific cooling requirements; heat load calculations should always be performed prior to selecting a cooling unit), the WhisperKOOL Platinum Split Twin Ductless Cooling System can accommodate approximately 3000 cu.ft. cellar size.

WhisperKOOL Platinum Split Series are often the most efficient way to cool a cellar. Condensers are typically noisy and require significant space for ventilation. By splitting the condenser and evaporator, 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.

The WhisperKOOL Platinum Split Twin allows you to decide where the evaporator unit and the condensing unit will be located. The condensing unit can be located up to 100ft. away from the evaporator unit. The evaporator unit will be mounted in the cellar or it can also be located nearby with ducting.

If you don’t mind seeing the grille of your cooling unit in your cellar, a wall-mounted split system is what you need. If you prefer your unit to be out of sight, you should get a fully ducted split system. The choice is yours.

    24V Thermostat Conversion Kit (OPTIONAL)

    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 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.

    Thank you

    I'm a huge fan of WhisperKool and been looking at the split type for a while now. Glad that I bought this one from your shop. Your website is very easy to use and support is very knowledgeable and answered all my questions.

    Very quiet

    It is very quiet which is great when I am admiring my collection. Also, I can't feel any vibrations unlike the previous one I used.
