Described in the simplest terms, a split system is a cooling unit wherein the evaporator unit and condensing unit have been “split” into two separate units instead of being contained within the same housing. The evaporator unit is located in or near your cellar, and the condensing unit is generally located outside, or in an attic or utility room.


The Platinum Split 4000 allows you to decide where the evaporator unit and the condensing unit will be located. The condensing unit can be located up to 100 ft. 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.

Note: A qualified HVAC-R technician is required for the installation of Platinum Split 4000 systems. Failure to have the system installed by a qualified technician will void the warranty.


*PLEASE NOTE: WhisperKOOL does not provide smart thermostat. 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 smart thermostat to run the equipment. The WhisperKOOL Customer Satisfaction Team does not provide technical support for smart thermostats.

3D Tour (Application Example)


3650 – 4315

The BTU/h value range 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.

Cellar Wizard

For more specific calculations, we have a tool which accounts for these variables. Please utilize this tool in order to ensure you are selecting the proper cooling unit for your application. Our tool is called the Cellar Wizard.

Note: The systems do not include a line set.

    Works great for my cellar

    I have owned a WhisperKOOL 7000 split system for the past three years. My wine collection is about 1500 bottles. The cellar has maintained a consistant 55 degrees all the time. I imagine the cooling unit could cool a much larger cellar than mine considering that it runs less than 50% of the time. Noise is not a factor as the evaporator unit in my cellar is very quiet, the condenser is outside in the side yard. The only thing i would change is the installation location. I should have mounted the evaporator above the doorway so it would not be seen. other than that, i am very satisfied with this product.
