WhisperKOOL Platinum 4000 – Split System


  • BTU/H: 3650 – 4315
  • Dimensions: * Evaporator: 13”L x 20”W x 10.5”H * Condenser: 13.97”L x 15.85”W x 9.86”H
  • Quietest Split Wine Cooling Unit

Described in the simplest terms, a Whisperkool Split System 4000 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 of this cooling unit is located in or near your cellar, and the condensing unit is generally located outside, or in an attic or utility room.

The Whisperkool Split System 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.

  • Condensing unit can be placed outdoors with purchase of exterior housing
  • 55ºF temperature differential between the cellar and condensing unit air intake temperature
  • KDT Digital Controller/Thermostat with 50-ft. cable
  • UV-C Lighting System available to prevent mold growth and maximize efficiency
  • 220V High Efficiency (H.E.) Condenser


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.
