Product Overview
WhisperKOOL Platinum Mini Split: Quick Decision Summary
Choose the Platinum Mini Split Ductless when the wine cellar is approximately 500 cubic feet or less, the room is fully insulated and vapor sealed, and a visible evaporator grille is acceptable. The remote condenser configuration helps remove compressor heat and noise from the cellar while allowing flexible equipment placement.

Small residential wine cellars, modern wine rooms, glass wine walls, and projects requiring remote condenser placement. |
| Rated Cellar Size |
Up to approximately 500 cu. ft. when the room is fully insulated, sealed, and protected with a proper vapor barrier. |
| Cooling Output |
2,101 BTU/h at the published 85°F condenser air intake condition. |
| System Type |
Ductless split wine cellar cooling system with an in-cellar evaporator and remotely installed condenser. |
| Professional Installation |
A qualified HVAC-R technician is required for installation and commissioning. |
Things to Know Before Ordering
- The cellar must be approximately 500 cubic feet or less under the stated sizing conditions.
- The room must be fully insulated and sealed.
- A properly installed vapor barrier is required.
- The ductless evaporator grille remains visible inside the cellar.
- The condenser can be installed remotely up to approximately 100 line feet away.
- Large glass areas, high ambient temperatures, or poor insulation can increase the required cooling capacity.
- Professional HVAC-R installation is required.
- This system is intended for wine-cellar refrigeration, not general comfort cooling.
Buyer Fit
Is This the Right Cooling System for Your Cellar?
Best For
- Wine cellars up to 500 cu. ft.
- Fully insulated, vapor-barrier sealed rooms
- Glass wine walls
- Installations requiring remote condenser placement
- Projects requiring quiet in-cellar operation
Not Suitable For
- Uninsulated basements
- Rooms without a vapor barrier
- General comfort cooling
- DIY installation without HVAC certification
- Cellars exceeding 500 cu. ft.
Sizing recommendation: If your cellar exceeds 500 cubic feet or has substantial glass, high ambient heat, exterior exposure, or other elevated heat-load conditions, consider the Platinum Split 4000 or Platinum Split 8000.
System Design
How the Ductless Split System Works
The Platinum Mini Split uses two separate refrigeration components:
| Evaporator |
Fan coil unit installed inside the wine cellar. |
| Condenser |
Air-cooled condensing unit installed remotely up to approximately 100 line feet away in a suitable utility room, attic, mechanical space, or outdoors with protective housing. |
Benefits of Remote Condenser Placement
- Heat is expelled outside the wine room
- Noise levels inside the cellar are reduced
- Installation flexibility increases
The ductless version includes a visible grille inside the cellar. If concealed airflow is required, a ducted split system may be more appropriate.
Installation
Installation & Construction Requirements
This is a professional-grade refrigeration system and must be installed by a qualified HVAC-R technician.
Required Conditions
- Fully insulated cellar including walls, ceiling, and door
- Proper vapor barrier on the warm side of the insulation
- Dedicated 115V, 15-amp circuits
- Properly sized refrigerant line set
- Condensate drainage planning
Failure to Meet These Requirements May Cause:
- Inability to maintain 55°F
- Continuous system runtime
- Condensation damage
- Premature compressor wear
- Voided warranty
Construction requirement: This cooling system will not compensate for poor cellar construction. Proper insulation, vapor control, sealing, drainage, and system sizing are essential to intended performance.

Questions & Answers
Frequently Asked Questions
Does this replace a regular air conditioner?
No. This system is designed specifically for wine cellars. It maintains 55°F storage conditions and humidity balance. It is not intended for general room cooling.
Can I install this system myself?
No. Installation must be completed by a qualified HVAC-R technician. Improper installation voids the warranty.
What happens if my cellar is not properly insulated?
The system may run continuously, fail to reach target temperature, or create condensation issues. A vapor barrier and insulation are mandatory.
How accurate is the bottle probe?
The liquid-temperature bottle probe measures the temperature of a liquid sample rather than ambient air, providing more accurate wine preservation monitoring.
How do I confirm that 500 cubic feet is correct for my space?
Capacity assumes proper insulation, sealed vapor barrier, limited glass exposure, and controlled ambient temperature. Excess glass, high ambient heat, or poor insulation may require upsizing.
What is the difference between ducted and ductless split systems?
Ductless systems have a visible grille inside the cellar. Ducted systems conceal airflow through ductwork and are preferred when minimal interior visibility is required.
Expert Sizing Guidance
Confirm the Cooling Load Before Ordering
The 500-cubic-foot rating assumes a properly constructed cellar with adequate insulation, an effective vapor barrier, controlled ambient conditions, and limited additional heat load.
If the project includes extensive glass, high ceilings, exterior-facing surfaces, warm surrounding spaces, or other heat sources, complete a professional heat-load calculation before choosing the cooling system.
