CellarPro Split systems are the most advanced refrigeration systems in the wine storage industry. By separating the
evaporator and condensing unit, our split systems are designed to keep the noise and heat away from living areas,
so the only sound you'll hear is the quiet hum from our variable-speed evaporator fans. CellarPro Split refrigeration
systems can be configured for indoor or outdoor use, and are designed to handle extreme temperatures from minus
20 to 110 degrees Fahrenheit. All CellarPro cooling systems are made in the USA and backed by the best warranty
in the industry.
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 ceiling and 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 1000 cubic foot wine cellar at 55 degrees with R-12 insulation
and 85 degree ambient temperatures is 3935 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.
We offer two configurations for our split systems: Valve Control and Electronic Control.
Our Valve Control
configuration requires both the condensing unit and evaporator to be independently connected to 115 volt AC power.
In this configuration, the condensing unit's "on" and "off" cycles are controlled by a factory-installed solenoid valve.
When used with our factory-installed compressor heater, our condensing units with valve control can be located in
environments with temperatures down to 0 degrees Fahrenheit.
Our Electronic Control configuration requires just the
evaporator to be connected to a 115 volt AC power source. In this configuration, the condensing unit is directly
connected with 115 volt wiring to the evaporator, which provides switched power to the condensing unit; therefore,
a solenoid valve is not necessary. When used with our factory-installed compressor heater, our condensing units with
electronic control can be located in environments with temperatures down to minus-20 degrees Fahrenheit.
CellarPro split refrigeration systems separate the cooling unit into two components: the evaporator and
the condensing unit. The evaporator is designed to be wall-mounted inside the wine cellar with factory-supplied
mounting brackets. The condensing unit is designed to be located outside the cellar, up to 100 equivalent
feet away, and can be configured for indoor or outdoor use.
Once installed, the evaporator and condensing units are connected by a pair of copper tubes called the line-set,
and the system is charged with refrigerant by a qualified HVAC technician. (Please refer to our line sizing chart
for more information about line-set diameters and insulation.) When our split systems are configured with Electronic
Control, the evaporator and condensing units also are connected to each other with 115V wiring, and the evaporator
is connected to an external 115V AC power source. When our split systems are configured with Valve Control, no wiring
is necessary to connect the evaporator and condensing unit; however, both components must be separately connected to
an external 115V AC power source. In both configurations, a condensate drain line will exit from the rear of the evaporator.
The condensing unit generates heat that must be dissipated during operation. For this reason,
the condensing unit requires 12 inches of unobstructed space in front of the coils, and ample
space in the ambient environment for the hot air to dissipate. If the condensing unit does not
have enough space for the hot air to dissipate, it will be forced to recirculate its hot air,
which will compromise its ability to create cold air inside the wine cellar.
A rule of thumb is that the ambient space should be as large as the wine cellar in order for
the hot air to dissipate. If the condensing unit will be installed in a confined space, we
recommend approximately 600-700 CFM of ventilation to ensure that the ambient environment won't
overheat. Our split condensing units are not designed to be ducted.
Modifications and Accessories
Our factory-installed compressor heaters will allow the cooling unit to operate in
temperatures down to 20 degrees.
We offer two drain lines, with and without a 100-watt condensate evaporator, for
wine cellar installations especially in high-humidity geographies.
We also offer a power cord modification that allows the cooling unit to be plugged into
an outlet inside (rather than outside) the wine cellar. We offer professional-grade air
filters that can be used to keep the condenser coils clean,
and louvered grills to cover both the front and the rear of the cooling unit.
