The WhisperKOOL Platinum Split 4000 Ductless is a high-efficiency, two-piece split wine cellar cooling system designed for discreet, wall-mounted installation inside the cellar without any ducting. With a dedicated air-cooled condenser installed outside or in a remote ventilated area, this system quietly and precisely maintains ideal cellar conditions in spaces up to approximately 1,000 ft³, depending on insulation and heat load. The system utilizes WhisperKOOL’s liquid-temperature bottle probe for true wine storage accuracy.
