Description
The WhisperKOOL Blow-Through 4000 Series is a compact split-system wine cellar cooling solution designed for stealth cooling applications where traditional systems may not fit cleanly. Ideal for wine walls, built-in cabinetry, soffits, and custom wine cellars, the Blow-Through 4000 supports ducted, ductless, and hybrid airflow configurations while keeping the cooling system hidden from view.
Featuring configurable airflow direction, a built-in condensate pump, dual-side service access, liquid-temperature bottle probe technology, and quiet centrifugal blower operation, the Blow-Through 4000 delivers reliable climate control with greater installation flexibility.
Compatible with WhisperKOOL ΩMEGA 110V H.E. and 220V Advanced H.E. Condensing Units, the Blow-Through Series is an ideal solution for modern residential and commercial wine cellar applications where aesthetics, performance, and hidden cooling integration matter.

Note: A qualified HVAC-R technician is required for the installation of your Blow-Through 4000. Failure to have the system installed by a qualified technician will void the warranty.
*PLEASE NOTE: WhisperKOOL does not provide smart thermostat. By selecting the 24V Thermostat Conversion Kit, you have acknowledged that the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. You will have to source and purchase your own 24V smart thermostat to run the equipment. The WhisperKOOL Customer Satisfaction Team does not provide technical support for smart thermostats.

BTU/h
3848 – 5351
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.
Wine Cellar Cooling Calculator
For more specific calculations, we have a tool which accounts for these variables. Please utilize this tool in order to ensure you are selecting the proper cooling unit for your application. Our tool is called the Wine Cellar Cooling Calculator.
Note: The systems do not include a line set.
