Choice of Configurations
CellarPro Air Handlers have multiple configuration options, including a self-contained system with a
choice of horizontal or vertical configurations, and a split system with a choice of indoor or outdoor
configurations. Our Air Handlers can be floor mounted through the wall, above the ceiling, or remotely
located from the cellar. They are designed to operate in temperatures ranging from 40 to 110 degrees
Fahrenheit, and down to minus-20 degrees Fahrenheit using our optional factory-installed compressor heater.
Cooling Unit Selection
To select the best cooling unit for your cellar, start by gathering the following information:
1. The cubic feet of the cellar,
2. The R-Value of the insulation inside the cellar walls,
3. The ambient temperature outside the cellar (during the warmest time of the year), and
4. The desired temperature inside the wine cellar
Using this information, find the "thermal load" of your wine cellar in the accompanying chart.
For example, the thermal load of a 2,500 cubic foot wine cellar at 55 degrees with R-12 insulation
and 85 degree ambient temperatures is 7806 BTUH.
Then, select a cooling unit that will produce equal or greater BTUH than the thermal load.
The BTUH produced by each cooling unit is listed at the top of the accompanying chart.
Air Handlers can be configured as self-contained systems, in either a horizontal or vertical orientation,
and placed in a remote location so that the cold air and the hot air can be ducted as necessary. The remote
location can be above the cellar, adjacent to the cellar, or in a remote location up to a total of 100
equivalent feet away from the cellar.
Air Handlers also can be configured as split systems, allowing the evaporator to be placed inside the cellar,
or located remote from the cellar and ducted. Separately, the condensing unit can be configured for remote
placement in an indoor or outdoor environment, allowing the noise and heat to be located away from living areas.
In a split system, the evaporator and condensing units are connected via copper tubing called the lineset.
Ducting Requirements—Cold Air
Cold air can be ducted to and from the cooling unit and the wine cellar using one or two 10-inch
ducts for the cold air exhaust, and one 10-inch duct for the return air from the cellar. Exhaust
ducts can be located in a choice of positions on the Air Handler.
A rule of thumb is that the indoor space should be the same size or larger that the wine
cellar to ensure that the hot air will dissipate properly. Only CellarPro Model 1800XTSx
can be exposed to outdoor spaces.
Ducting Requirements—Hot Air
Air Handlers generate a significant amount of heat, and require cool, fresh return air in order to
operate properly. CellarPro Air Handlers are designed to handle Fresh Air Return ranging from 40
to 110 degrees Fahrenheit out of the box. If Fresh Air Return temperatures drop below 40 degrees
Fahrenheit, our optional compressor heater will be required.
If the hot air exhaust and the Fresh Air Intake go to and come from the same space, it must be
large enough for the hot air exhaust to dissipate properly. If the space is too small, the air
in the space may heat up and cause the cooling unit to recirculate its own hot air. As a rule
of thumb, the indoor space should be about the same size, or larger, than the cellar to ensure
hot air dissipates properly.
Optional Integrated Heater and Humidification Systems
Our Air Handlers are offered with a choice of two optional integrated heaters that can be added
to the cooling unit and used in installations where the wine cellar will be exposed to
temperatures below desired wine storage temperatures. Our Air Handlers also offer an optional
integrated humidification system that requires an external water source, and allows you to add
and maintain optimal humidity conditions inside your cellar.
Other Modifications and Accessories
Our factory-installed compressor heaters allow the cooling unit to operate in temperatures down to
20 degrees Fahrenheit. We offer a factory-installed remote display that allows the control panel
to be located away from the cooling system, either inside or outside the wine cellar, and connected
via 18-gauge thermostat wiring. The remote control display is recommended when access to the control
panel is not convenient.
