MCI would certainly argue with both
Carrier and Thermo King over whose
machinery design is the most energy effi-
cient and its stand at Intermodal 2008 of-
fered plenty of material to support the case
for its own innovative Star Cool machine.
Equipped with a Bitzer aluminium
reciprocating compressor running on
R134a and driven through a Danfoss fre-
quency converter that allows infinitely
variable capacity control by varying the
motor speed, the company claims the Star
Cool offers the lowest TCO of any de-
sign on the market. “This has been
achieved as a result of its fundamental de-
sign rather than through supplementary
software solutions to lower energy con-
sumption by alternate temperature con-
trol algorithms,” the company says. “We
already have the lowest energy consump-
tion in all operating modes when run-
Copeland
scrolls into
Thailand
Such has been the level of demand
from reefer container machinery
OEMs that Emerson Climate Tech-
nologies has taken the decision to start
production of Copeland digital scroll
compressors for transport applications
at its manufacturing plant in Thailand.
The aluminised Copeland digital
scroll compressor has been used by
Thermo King in its Magnum R404A
machine since it was launched in 2002
and has been adopted more recently
by Carrier Transicold for its new
PrimeLINE design running on R134a.
As reported in the main article, Thermo
King sold close to 19,000 Magnum,
units last year, while Carrier reports sales
of over 20,000 PrimeLINE units in its
first year of production.
Emerson says the Copeland dig-
ital scroll is gaining popularity and uti-
lisation in reefer container applications
because of the design’s inherent effi-
ciency advantages. It features an En-
hanced Vapour Injection (EVI) system
to deliver higher cooling capacity and
compressor unloading through digital
modulation technology to minimise
energy consumption
An aluminised coating system pro-
vides the compressor with a high level
of resistance to corrosion, while the
design is claimed to be lighter than
other, non-digital scrolls used in reefer
container machinery.
Digital scrolls for the transport
market have hitherto been manufac-
tured at Emerson’s plant in Sidney,
Ohio. Shifting some of the produc-
tion to Thailand, says Enerson, will
guarantee the level, of supply needed
to meet OEM demand and allow de-
livery lead times to the Carrier manu-
facturing facility in Singapore and the
Thermo King plant in Suzhou, China,
to be shortened considerably. a74
