Frequently Asked Questions

Answers to common questions about the Flex Series, installation flexibility, and system performance.

The CellarCool Flex Series is a compact split-system evaporator designed for hidden wine cellar cooling applications. It is engineered for soffits, built-in cabinetry, wine walls, adjacent mechanical spaces, and in-cellar installations where traditional wall-mounted systems may not be ideal.

Traditional wall-mounted evaporators typically pull and supply air from the front of the unit. The Flex Series moves air through the unit from one side to the other, allowing the evaporator to be hidden, ducted, or integrated into custom layouts. 

  • Concealed cooling without the need for ducting
  • Flexible airflow orientation
  • Soffit or cabinetry integration
  • Mini ducted or hybrid airflow layouts
  • Tight installation spaces where a standard wall-mounted evaporator is not practical

Common applications include: 

  • Soffits 
  • Built-in cabinetry 
  • Wine walls 
  • Adjacent closets or mechanical rooms 
  • Walk-in wine cellars 
  • Behind decorative wooden grilles Inline ducted applications 
  • Custom millwork

The unit supports three airflow kit options:

  • Ductless Airflow: Includes two air diverters for ductless airflow
  • Ducted Airflow: Includes two 8-inch duct plenums for fully ducted airflow
  • Hybrid Airflow: Includes one air diverter and one 8-inch duct plenum

Fully ducted applications can support duct runs up to 25 feet. Diverters can direct airflow left, right, or downward depending on the installation layout.

The Flex Series supports 16 different airflow configurations using optional ductless and ducted airflow kits, allowing the system to adapt to a wide range of wine cellar layouts and installation requirements. These configurable airflow options allow the Flex Series to be integrated into soffits, cabinetry, wine walls, adjacent mechanical spaces, and other custom applications where traditional airflow layouts may not be possible.

The Rotatable Air Deflector allows airflow to be directed left, right, or downward to accommodate different installation layouts and improve air circulation within the cellar. 

The Flex Series is compatible with: 

Additional compatibility with communication and pump-down configurations may vary by model. 

The Variable Speed Fan Switch allows installers or technicians to adjust airflow and fan speed based on the application, helping balance cooling performance, airflow, and sound levels. 

The Flex Series includes: 

  • KDT Digital Touch Display with system alerts, alarm notifications, & can be installed up to 50 feet away 
  • Bottle Probe for liquid-temperature monitoring
