WhisperKool Quantum Split System

Quantum Split System

The Quantum Series of cooling units are the highest-capacity units that we offer. KOOL your collection with WhisperKOOL and Rhino Wine Cellars.

Described in the simplest terms, a split system means that the two essential parts of a wine cooling system (the evaporator unit and the condensing unit) have been separated, or “split” into their own respective units. The evaporator unit is located in or near your cellar, and the condensing unit is generally located outdoors or in an attic or utility room.

A Cold Weather Start Kit comes standard in every split system. Split systems can be installed in a variety of ways, and the condensing unit may be located in a mechanical room, basement, backyard, or even a rooftop. The condensing units which WhisperKOOL units use were designed to operate between temperatures of 20°F and 110°F. However, there are some areas in the country which may drop below 20°F in winter. When 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 use 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 cold weather start kit bypasses the low-pressure switch on startup and uses heaters installed on the receiver to raise the pressure and allow the system to start.

The Cold Weather Start Kit enables WhisperKOOL to operate in environments as cold as -20°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.


  • A qualified HVAC-R technician is required for installation. Failure to have the system installed by a qualified technician will void the warranty
  • 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 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 thermostat to run the equipment.
