    Temperature Differential


    Digital Thermostat

    The WhisperKOOL split system is designed with a 55-degree temperature differential. This means the unit can operate correctly even if the ambient temperature outside (or where ever the condenser unit is mounted even) in 110 degree heat. This is a significant improvement over most cooling units designed for wine storage.

    The system includes both the evaporator and condenser units.

    The WhisperKOOL split cooling system requires professional installation by a licensed refrigeration technician. The contents of this system does not include a line set.

    Additional Info

    split system diagram

    The Split System is often the most efficient way to cool a cellar. Cooling unit condensers are typically noisy and require significant space for ventilation, in most cases the cellar location does not include an area for these functions. By splitting the cooling system, 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. A licensed HVAC/R technician is required for the installation.


    Please have technician complete and send the Split System Start Up Checklist to activate warranty coverage.
