Compressors Designed
for Use with CO2
In Specialized

Refrigeration
Applications
ST. LOUIS, April 14,
2008 –
Emerson Climate
Technologies, a
business of Emerson
(NYSE: EMR),
announced today the
launch of Copeland
Scroll® compressors
designed for use
with CO2
(Carbon Dioxide)
refrigerant in
low-temperature
subcritical cascade
cycle applications.
The company is
working with U.S.
OEMs serving the
supermarket
refrigeration
industry to test
systems using the
new Copeland Scroll
compressors.
Countries in Europe
are increasing their
usage of CO2
as a refrigerant due
to its neutral
impact on Global
Warming and Ozone
depletion, as well
as harsher
regulations than
those in the United
States on the use of
other refrigerants.
“As a global
company, we’ve kept
a close watch on the
use of CO2
as a refrigerant in
refrigeration
applications,” said
Rajan Rajendran,
director of
applications
engineering for
Emerson Climate
Technologies,
Refrigeration
Division. “For
nearly all
applications, we
think the answer to
minimizing
environmental impact
is still the use of
high-efficiency
equipment and the
reduction of
refrigerant leaks.
HFC refrigerants
often offer superior
energy efficiency
versus CO2.
However, we are
seeing that CO2
can offer comparable
system efficiency
when applied in a
subcritical cascade
refrigeration cycle,
which can be applied
in supermarket
applications.”
Emerson Climate
Technologies’
subcritical CO2
Copeland Scroll
product line was
previously launched
in Europe to
positive feedback.
Emerson has received
UL approval in the
U.S. and is
currently shipping
samples and sharing
product information
with major U.S.
supermarket OEMs and
is working with
retailers to test
the CO2
systems.
The Copeland Scroll
compressor is
hermetically sealed,
eliminating possible
leak points found in
reciprocating
compressors (such as
gaskets and bolted
joints). This
reduces the
potential for direct
refrigerant leaks.
The compressor’s
strong steel shell
allows these
compressors to
withstand the high
pressures associated
with CO2
systems.
The most significant
environmental impact
of HVACR systems is
derived from the
byproducts of power
generation needed to
run the system. Also
harmful are
refrigerant leaks, a
result of the lack
of proper handling
during service and
disposal. These
byproducts and
leaked refrigerant
play a role in
Global Warming and
Ozone depletion. A
complete summary of
the direct and
indirect impact of
different systems
was detailed in a
recent Emerson
Climate Technologies
webcast and can be
