Quantum Series Cooling Systems SS9000

We have expanded our product line with the development of higher capacity cooling systems. Cellar contractors have asked for a cooling system that can handle larger and more challenging wine cellars. Introducing the Quantum Series. This split system includes multiple ducting options allowing for flexibility on installation. The air handler can be ducted up to 25 feet creating a virtually quiet cellar environment. These systems are capable of maintaining wine cellars up to 4000 cubic feet in size. Designed to operate in ambient conditions as low as -15 degrees. The evaporator coil is coated with electro fin coating to minimize corrosion. Designed with the highest quality, professional grade parts for longevity and performance, it also offers ease of installation and accessibility. The Quantum Series Cooling Systems will give you that extra boost of cooling power, backed with a 2 year warranty, and the quality you have come to expect from WhisperKOOL.
Quantum SS9000
The Quantum Series cooling units is our newest, most advanced cooling systems.  The fully ducted split systems come in two sizes, 9000 BTUs and 12000 BTUs. Utilizing 404A refrigerant, these systems have the built in capacity to be installed outside in cold weather climates where temperatures get as low as -15 degrees.  Simple to install by a certified technician, our pump down technology does not require any wiring from the condenser to the evaporator.  Featuring interchangeable panels which allow the installer to direct the air flow in the most efficient direction to maintain maximum efficiency.

BTUh Rating:
There are circumstances in which a cellar design may require a larger unit due to some existing design restrictions. There are several factors such as glass, stone, concrete, etc. which will seem adequate but do not offer the insulation capacity required to maintain the optimum environment. We recommend purchasing a unit with a larger capacity to compensate for the design limitations. Under sized cooling units can lead to pre-mature failure and/or prevent the system from reaching the desired set temperature. As a result they are not covered under warranty.
