cycling, high pressure resets, low pressure cut-outs and
liquid flood-back conditions that cause unexpected
performance losses or worse, unplanned equipment failure.
As part of the Emerson family of products, Copeland
Outdoor Refrigeration Units provide unsurpassed access to
system status, diagnostics, and operational control.
3 – Flexibility
The light weight and slim-line profile ease the installation
process. The ultra quiet variable-speed fan motor signifi-
cantly reduces exterior sound levels, allowing use in noise
restricted residential zones. With high and low ambient
operation capability, coated coils for coastal applications,
multi-refrigerant capabilities, and optional wall mounting
capability, the units deliver unmatched mounting and
environmental location flexibility.
Copeland Outdoor Refrigeration Units are perfectly suited
for walk-in and display case applications. All units integrate
the many benefits of scroll compressor technology, fan
speed control, and advanced on-board diagnostics,
delivering higher energy efficiency and lower sound levels,
while ensuring reliable performance and operation in
foodservice applications.
Two sound values shown represent the X-Line unit’s lowest and highest operating dBA measurements, or typical industry outdoor unit published data, for both
MT and LT products. Sound pressure values are 10 feet from the unit at 25°F
evap for MT and -10°F evap for LT at 90°F ambient. A sound reduction of up to 3
dBA will occur in ambient temperatures below 70°F This data is typical of ‘free
field’ conditions for horizontal air cooled condensing units and may vary depending on the condensing unit installation. There are many factors that affect
the sound reading of a condensing unit such as unit mounting, reflecting walls,
background noise and operating condition.

Copeland Digital Outdoor Refrigeration Unit, X-Line Series
The compact solution for continuous capacity modulation
The Copeland Digital Outdoor Refrigeration Unit sets a
new standard for energy effi ciency, reliability, and
installation fl exibility. With 20-100% modulation now
available and expanded refrigerant approvals, its industry
Digital compression technology means fewer condensing
units are needed to install and maintain for numerous
refrigeration loads, which results in fewer line runs, lower
refrigerant charges, and faster installation.
leading on-board diagnostics and system protection can
help optimize operational effi ciency and deliver peace of
mind to any end user. Digital X-Line units are available for
applications commonly found in today’s food service and
food retail establishments.
The perfect solution for refrigeration applications with
wide load variation:
• Walk-In Coolers • Food Preparation Rooms
• Display Cases• Industrial Process Chillers
A Superior Solution for Food Safety
Digital modulation enables tighter control of case temperatures. This provides supermarkets and foodservice establishments
with the security of knowing that their food is safe from harmful bacteria growth and other harmful micro-organisms.
A Superior Solution for Energy Savings
Traditional modulation technologies consume close to
full load energy no matter what the required capacity.
Copeland digital scroll compressor technology reduces
power consumption linearly as it modulates capacity
resulting in optimum system performance and control,
as shown in Chart A.

4-1273 Factors to Consider in Converting Compressor
Rated Capacity to Actual Capacity
Max Over-current rating applies to the condensing unit only. Additional evaporator fan or defrost heater loads must be considered. See evaporator manufacturer literature for additional load
requirements.
† Defrost relay for single phase heaters only. For three-phase heaters, additional contactors are required.
*Data for XFAM models also applies to equivalent XFAP models.
This refrigeration system is designed and certifi ed for use in walk-in cooler applications. See Emerson.com/OPI for complete specifi cations.
*Data for units containing ZF compressors are rated at 40 degree return gas; ZI compressors are rated at 65 degree return gas
This refrigeration system is designed and certifi ed for use in walk-in freezer applications. See Emerson.com/OPI for complete specifi cations.
