Our Large Air Handler cooling systems use a common approach to optimize compressor size, fin spacing
and coil size, and blower air fan. The goal is to maximize cooling power without stripping humidity and
maintain consistent temperatures.
Our Large Air Handlers offer a wide array of modifications, such as a networkable controller, integrated
humidifier and integrated heater.
Evaporator Housing
The housing is manufactured from aluminum for light weight, corrosion resistance and aesthetics. The
cabinet is structurally reinforced throughout to provide a stable and secure platform for the components.
The evaporator section is insulated for thermal efficiency. Panels are fastened with quick release hardware
to simplify internal access.
Evaporator Coils
The unit has a large-face A-Frame coil for increased cooling efficiency and efficient power usage. The copper
tube + aluminum fin evaporator coils are mounted in a stainless steel condensate pan with a condensate
safety switch to guard against condensate overflow. Commercial-grade Electrofin coating protects the
evaporator coil from leaks and corrosion.
Blower and Blower Motor
Our Large Air Handler units incorporate a blower and motor in a draw-thru configuration for even air
distribution across the coils. The large blower runs at low RPM that minimizes noise and motor horsepower
consumption. The blower assembly is mounted to an internal chamber to further reduce noise levels.
Electrical System
The electrical system features a Class 2, 24 VAC control circuit, and includes all
required contactors, fuses and/or circuit breakers. Field connections (24 VAC)
and high voltage connections are provided through separate terminal blocks in
the electric box. A defrost controller is mounted to the unit and manages defrost
cycles, freeze protection and high/low temperature alarms. The temperature
control circuit is compatible with standard or networkable 24 VAC thermostats.

Refrigeration System Components
Easily accessible components in the Evaporator include: thermal expansion valve, pump-down solenoid
valve, suction line service access port, and condensate overflow emergency shut-off float switch.
Condensing Unit components include an electronic controller for low pressure control cut-in/cut-out
adjustment, mounted filter drier and sight glass, and liquid/suction service valves.
All units are evacuated and charged with dry nitrogen prior to shipment. Two dedicated power supplies
are required, one to the evaporator and one to the condensing unit. No communication wiring is
required between the Evaporator and the Condensing Unit. The Condensing Unit enclosure is suitable
for indoor or outdoor installations.
Without the optional Integrated Humidifier, the Evaporator operating range is 45°F to 62°F cellar
temperature. With the Integrated Humidifier, the Evaporator operating range is 51°F to 62°F. In addition
to managing the defrost cycle, the defrost controller is programmed to ensure that the cellar does not
drop below the minimum allowable temperature. The defrost cycle is time initiated, temperature
terminated, with a factory default of 1 hour, field adjustable in one-hour increments. If defrost is not
required, the system will terminate the defrost and return to refrigeration automatically after a 3-minute
delay.
Compressor
All systems incorporate scroll compressors for high reliability, high efficiency and
low noise. Compressors are mounted on vibration isolators to minimize noise
transmission to the cabinet.
Evaporator Ducting
Flanges are provided on the Evaporator air intake and exhaust plenums for easy attachment of ducting.
Using 14" diameter R-6 insulated flex ducting, the Evaporator can be ducted up to 100 equivalent feet (50
equivalent feet per duct). Using R-6 insulated hard ducting, the Evaporator can be ducted with maximum
external static pressure of 0.3"wg and minimum cross sectional area of 153 sq inches. Units are rated to
0.30”wg external static pressure. All ducting must be insulated to R-6 minimum.
The condensing unit cannot be ducted.
Evaporator Air Filter –FOR NON-DUCTED INSTALLATIONS ONLY
We provide a Merv 5 air filter measuring 12”x25”x1” for the Evaporator cold air intake. The purpose of the
filter is to keep the evaporator fins free of debris; it is not an air quality filter. This filter is for non-ducted
operation only. If the Evaporator is ducted, the filter must not be installed at the unit.
To use a filter in a ducted application, the filter size must be increased to offset the duct pressure loss
from the filter. In a ducted application, the filter must be at least 2.6 ft^2 (approx. 16”x24”), 1” deep
maximum, non-pleated, and Merv 5 or less.

Options & Upgrades
Electrode Canister Humidifier
We offer an integrated Electrode Canister humidifier inside the cooling unit that
provides humidification and allows you to maintain ideal humidity conditions inside
the cellar. The humidifier senses cylinder current draw, automatically flushing and
filling the cylinder to control the mineral content of the water and humidity output.
The output is field adjustable from 1 to 5 lbs/hr. A “Change Cylinder” light alerts
service personnel when the humidifier requires service.
The humidifier must be connected to a water line. When a humidifier is purchased,
we provide a 1/4” water supply shut off ball valve which is mounted on the exterior
of the cabinet housing.
A dedicated Humidistat is included with the humidifier, because most 24VAC
thermostats will only allow humidity control up to 50%RH. The Humidistat must be
installed inside the cellar near the return airflow in an area with good air circulation.
The Humidistat controls the humidity from 5% to 70%RH in 5% increments. The
humidistat controls only humidity and is not Internet accessible.
Electric Heat
For wine cellars that are exposed to conditions below 55°F temperatures, CellarPro
Air Handlers can be configured with optional integrated heaters to provide 3kW
(10236 BTUH) of heat. The unit incorporates a factory installed nichrome wire
heater. The heater has low voltage thermal safety cutouts with automatic reset and
a second power line fuse link (over-temperature) safety device.
Internal Condensate Pump
We offer an integrated condensate pump that will be mounted in the evaporator
drain pan. This option includes 25ft of 1/4”ID PVC drain line. In the event that the
condensate pump cannot remove the water fast enough, the emergency shut-off
float switch (included as standard equipment) locks out the compressor until the
condensate pump has emptied the drain pan.

Ecobee Networkable Thermostat
The cooling unit is compatible with most 24V Networkable
Thermostats (sold separately).

display in an attractive, backlit, easy to install wall-
mounted unit.
