WhisperKOOL Platinum Mini Split. is a compact wine cellar cooling unit that cools wine cellars up to 500 cubic feet

The Platinum Mini Split is small and compact yet powerful, and quiet. This compact sized wine cooling unit can cool rooms as small as 500 cubic feet and less. It is the perfect answer for a converted closet, pantry, and/or economical cellar. As with all of our Platinum Models, the Platinum Mini Split comes with our most advanced controller and gives the user complete control over their cellar environment.

Please note it is strongly recommended that you get the exterior housing with the WSSMINI regardless of positioning.  Without the housing, the inner fan is exposed.  There is no additional delivery cost if the housing is ordered with the cooling unit.  A delivery fee will apply if the housing is ordered on its own. 

Key Features:

  • 220V condenser
  • Ultra quiet
  • Superior electronic control
  • Energy saving mode
  • Liquid bottle probe
  • Humidity control

Although the cooling units are rated for various size rooms, the thermal load may require a larger sized cooling unit.  Thermal load may be affected by glass in the cellar, room positioning or other factors.  Please let a Rosehill Wine Cellar rep make some suggestions for you if needed. 



WhisperKOOL Split System Series

The WhisperKOOL Split Wine Cellar Cooling System requires professional installation by a licensed refrigeration technician.

WhisperKOOL's Split Systems combine industry leading components with a elegantly simple engineering to offer quiet and efficient operation for an optimal wine storage environment.

The Platinum Split

The Platinum Split sets the standard for in cellar split system installations. The platinum line allows for improved airflow efficiency (25%) and operates 10% quieter than the previous split systems. At the same time it is 35% smaller than the previous split system (4000 & 7000).
The split system still uses Vinotheque's liquid bottle probe for monitoring the actual liquid temperature. The fully Ducted system allows for virtually silent cellar as unit is mounted up to 25 duct feet from the cellar.

  • Quiet and efficient operation
  • Advanced electronic control system
  • Liquid bottle probe
  • Flexible installation
  • Condensing unit can be placed outdoors w/optional housing
  • KDT controller allows for wall mount or flush mount installs. 
  • All ceiling mount splits to come with KDT Plus controller 
  • The Split systems come as 110V for both the Evaporator and Condenser (optional 220V condenser available on some units)

Ceiling Mount Upgraded System Features:   2020 enhancements to the 4000/8000 & Twin ceiling Mount cooling system include:  

- line set, drain line and electrical will now be located at the bottom of the evaporator allowing for easier access
-multiple fan speeds to allow for quieter setting.  
- superior e-coating on the coils for longevity.  
- flare fittings to make installation easier for the HVAC technician
- improved grill for better airflow in cellar
-Redesigned internal grill (Bee-hive pattern) reduces noise by 10 dB
-Recommend using PVC drain line for better longevity, no kinks or leaks to worry about


Designed with Wine Storage in mind: The WhisperKOOL split systems are designed to maintain the optimal temperature and humidity levels. Allowing for these optimal conditions is conducive to the proper aging of fine wines.

Humidity control: The Split System cooling units are designed to maintain relative humidity at 50-70%. The proper Humidity level is managed through the design and engineering of the unit. There are no separate switches for controlling humidity.

Quiet State of Art Operation: Years of experience with our self contained cooling units has resulted in a revolutionary design that accounts for a number of environmental conditions unique to wine cellars. WhisperKOOL's Split Systems combine industry leading components with a elegantly simple engineering to offer quiet and efficient operation for an optimal wine storage environment.

Flexible Indoor/Outdoor Condenser Installations: These Split Systems offer the ability to install the condenser up to 100 feet away from the wine cellar, in either indoor or outdoor conditions. The split system's flexibility when it comes to installation is a home builders and architects dream.

Temperature Differential:

The WhisperKOOL PLATINUM split system is designed with a 70-degree temperature differential. That means the unit can operate effectively even if the ambient temperature outside (or where ever the condenser unit is mounted) is a scorching 125 degree heat.

The Split Cooling System includes both the evaporator and condenser units. If you will be putting the condenser outside, you will need the optional exterior housing.

WSS COLDSTARTER, Cold Weather Starter Kit - now included with Whisperkool Split system

Worried about your cooling unit functioning properly in the cold? The Cold Weather Starter Kit will melt all of your worries away, and keep your wine at the ideal temperature. 

The Cold Weather Starter Kit is designed as an electronic bypass system made to ensure that your cooling unit's pressure stays at optimal levels. When it gets cold outside the pressure within your cooling system drops. This causes a problem for cooling systems that have a pump down cycle and a low pressure switch that turns the compressor on and off. If the temperature falls below 20°F the pressure will be too minimal to turn on the compressor causing a major problem. Fortunately, the Cold Weather Starter Kit can save the day, by bypassing the low pressure switch on start-up and keeping the pressure high enough so that your unit can even function at -15°F! 

Extends Condensing Unit's cold weather tolerance from 20°F/-6.5°C to -15°F/-27°C. 

If the condenser will be placed outside, you will also need the exterior enclosure.

WhisperKOOL Wine Cellar Cooling Systems Feature:

A new generation of wine cellar cooling units... Engineered for superior performance:

Condensate evaporator system

WhisperKOOL designed their wine cellar cooling systems to collect and dissipate any excessive condensation which may accumulate during the cooling process. First a heating element can burn off the collected condensate and evaporates it through exhaust ports on the rear of the unit. Secondly, all WhisperKOOL's units come with a drain line necessary for the removal of any additional condensate. This drain line is an essential back up system for the Condensate Evaporator, and is strongly recommended. If the unit is installed in a high humidity area, WhisperKOOL suggest that its employment is mandatory.


For the Split System series, a 24V option is also available which allows you to tie into your home electronic thermostat or home automation system, please inquire.  

220V Condenser

Units come standard with both pieces needed 110V power.   For higher efficiency, order the 220V condenser option.   


Like most wine cellar cooling units, these units are designed to be positioned high on the wall in the wine cellar. Think warm air rises; cold air falls. 

In a properly constructed wine cellar, the WhisperKOOL wine cellar cooling system is designed to cool your wine collection between 50°F to 70°F.


Additional Shipping charges may be charged for accessory items ordered on their own without the cooling unit.
