CellarPro AH18Sx-EC Air Handler Cooling System (P/N 34209). Our Split Wine Cellar Refrigeration Units are rated for exterior usage and designed for cellars up to 7000* cubic feet. Thus providing ducted refrigeration specifically designed for wine cellars.
All air-cooled Wine Cellar Refrigeration Units equipment requires fresh air intake to dissipate the heat generated by the cooling unit. The fresh air intake CAN NOT come from the wine cellar space. It must come from space outside the cellar.
- Now with energy-efficient EC Fans on the cold side
- The evaporator features an aluminum body for lightweight, corrosion resistance, and aesthetics
- Quick-release hardware simplifies internal access
- Scroll compressor provides high reliability, high efficiency, and low noise
- The insulated evaporator compartment provides maximum thermal efficiency.
- A-frame evaporator construction increases cooling capacity and reduces power consumption.
- Speed-optimized ECM blower motor in a draw-thru configuration provides even air distribution across the evaporator coils with 1300 CFM

15,500 SENSIBLE BTUH @ 55F.
CellarPro’s AH18Sx-EC split cooling system (1.5 Ton Nominal) is suitable for wine cellars up to 7000 cubic feet* in both commercial and residential wine cellars. The evaporator module features a powerful energy-efficient centrifugal EC fan that can handle ducting up to 0.30″wg external static pressure (equivalent to 14″ diameter using R6 insulated flex ducting, or 153 sq. inches area using R6 insulated hard ducting.)
The BTU/h value 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.

Warranty Resources
– Warranty Overview
To activate your warranty, you must complete and return our – Split Installation Checklist.

Cold Temperature
- Compressor Heater: protects the unit when installed in environments that drop below 40F down to 20F – Included as standard equipment.
- Fan Cycling Switch: supports the unit in temperatures below 20F and as low as -20F when configured with Electronic Control and combined with our compressor heater. Included as standard equipment
Remote Thermostats, Displays & Probes
- Networkable Thermostats #27346 and #27310: Included as standard equipment allowing connection of your cooling unit to a networkable, Wi-Fi enabled thermostat (sold separately, Ecobee SmartThermostat Pro #31453). Must be ordered at the same time that the equipment is ordered. Other limitations apply – read the networkable thermostat description for more information.
Heating & Humidification
- Integrated Heater #32034: adds 3000 watts of heat through the cooling system when the cellar is in an unheated environment and will be exposed to temperatures below desired wine storage temperatures.
- Integrated Humidifier #32035: provides humidification with digital control inside the cellar when attached to an external water line.
Condensate Pump
- Internal Condensate Pump: Internal condensate pump is factory-installed and includes 25ft of 1/4″ID PVC drain line.
