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.
