hard to ensure that your walk-in cooler or freezer is as reliable and energy-effi cient as possible.
We’re pioneering new refrigeration technologies, from compressors and condensing units to
electronicsand monitoring. And we have the resources to make sure the job gets done right.
Emerson offers a wide range of innovative products, solutions, support, training and tools –
all designed to make life more comfortable and your job easier. Our portfolio of brands offer
innovative, industry-leading solutions that combine technology and engineering for the
benefi t of our customers, our environment, and our future.
Copeland Scroll™ Compressors
for Refrigeration
The freezers in the newer
Copeland Scroll compressors have
earned a reputation for reliability and
lower energy costs. Unlike compressors
which use pistons (including hermetic
and semi-hermetic compressors), scroll
compressors have only two moving
scroll members. This difference results
in a more reliable, energy effi cient walk-
in, which translates into less downtime
and lower energy bills.
With more than 170 million Copeland
Scroll™ compressors installed, you’re
not just choosing a compressor, you’re
choosing nearly 30 years of scroll innovation and expertise. And, protecting
your reputation by selecting a compressor that is of the highest quality in the
commercial refrigeration market. With
our complete lineup of compressors for
low-, medium- and extended mediumtemperature applications for walk-in
coolers and freezers, we’ll help you
select the confi gurable solution that fi ts
your needs. Since our compressors are
distributed in the US, we can help ensure
compressor and service availability for
our customers.
HOW SCROLL COMPRESSORS WORK
Gas enters an
outer opening as
one scroll orbits
the other.
Gas is continually compressed
to the center of the scrolls,
where it is discharged through
precisely machined ports and
returned to the system.
restaurant stores use mostly
scroll compressors and they are
extremely reliable. In fact, we’ve
been servicing Copeland Scroll
compressors in restaurants for
about nine years and had
only one go bad.

The open passage is
sealed as gas is drawn
into the compression
chamber.
During actual operation, all
passages are in various stages
of compression at all times,
resulting in near-continuous
intake and discharge.
As one scroll
continues orbiting,
the gas is compressed
into an increasingly
smaller ‘pocket’.

Copeland Scroll Outdoor Refrigeration Unit,
X-Line Series
Copeland Scroll Digital Outdoor Refrigeration Unit,
X-Line Series
The Copeland Scroll Outdoor Refrigeration Unit, X-Line Series
sets a new standard for energy effi ciency, reliability, and
installation fl exibility. With capacities now available from ¾ to
6 HP and expanded refrigerant approvals, its industry leading
onboard diagnostics and system protection are available for
more applications commonly found in today’s foodservice
establishments.
The Copeland Scroll Outdoor Refrigeration Unit was designed
with three factors in mind:
Energy Efficiency
Scroll compressor technology, variable speed fan motors,
large capacity condenser coils, and advanced control
algorithms, work together to signifi cantly reduce energy
consumption.
Reliability and Communications
Equipment reliability is greatly enhanced by combining
the proven reliability of Copeland Scroll compressors with
advanced CoreSense™ technology. Each unit has built-in
CoreSense Diagnostics and protection that can alert and
record alarms independently or communicate with building
management systems.
Building on the fi eld-proven Copeland Scroll and X-Line
Outdoor Refrigeration Unit platforms, the Digital X-Line
Series delivers superior food safety and energy effi ciency in
small-format supermarkets, convenience stores and
foodservice establishments.
Digital modulation enables tighter control of case temperatures, giving operators the security of knowing their food is
kept safe and at maximum quality. The Digital X-Line Series
combines compression technology with variable-speed fan
motor control, large-capacity condenser coils, and smart
protection and diagnostics to meet today’s challenging
refrigeration requirements.
Ideal for walk-in coolers and display cases, digital X-Line units
deliver more precise, reliable refrigeration, longer-lasting
equipment, and lower energy bills in medium-temperature
applications.
Energy Efficiency Advantages
• Substantial annual energy effi ciency improvements
• Reduced compressor cycling
• Longer equipment life
• Decreased electrical load at startup
Flexibility
The ultra-quiet variable-speed fan motor signifi cantly reduces
exterior sound levels and is combined with a lightweight
weather-resistant cabinet, slim footprint, and optional wall
mounting capability to deliver unmatched installation fl exibility.
