Product Details
WhisperKOOL Quantum Twin 18000 for Massive Wine Cellar Cooling
The WhisperKOOL Quantum Twin 18000 Split Ducted Wine Cooling System is the largest unit in this range, cooling cellars up to 5,000 cu ft. This fully ducted split system supports up to 25 feet of ducting, so the equipment sits away from your wine room.
Ideal for both commercial and residential use, the Quantum Twin 18000 delivers up to 18,250 BTU/h with precise temperature and humidity control to safeguard even the most extensive wine collections. It features a stainless steel drip tray for easy maintenance, a sleek black metal exterior kit for a modern aesthetic, and a three-speed fan switch to customize airflow as needed.
The external insulation blanket enhances thermal efficiency, while the optional UV-C lighting system helps protect internal components from microbial growth.
Engineered with premium components, this powerful system is capable of operating in ambient temperatures as low as -15°F, ensuring reliable performance even in challenging conditions.
The Quantum Twin 18000 runs at 58 dBA at the evaporator and 52 dBA at the condenser, which is the loudest in this range, so plan the equipment location accordingly.
BTU/h value range: 13,806 – 18,250
