Star performer boosts chill times
February 1st 2009 Star Refrigeration has
designed and manufactured
an efficiency boosting
cooling system for Granville
Food Care in Northern
Ireland to replace an existing
R22 plant and increase
production to meet demand
from UK retailers.
Star's turnkey cooling
solution comprised a stateof-
the-art ammonia and
carbon dioxide (CO2)
cascade plant. Operating on
natural refrigerants, the dual
purpose plant provides
cooling for both blast
freezing and cold storage.
The cascade plant
supplies cooling to three
cold storage areas and seven
blast freezers at the
Granville facility. Star's
refrigeration system is one
of the first in Northern
Ireland to use CO2
technology for blast
freezing.
"The ammonia and CO2
cascade plant has allowed
Granville to reduce energy
consumption and gain a
significant increase in
throughput, by improving
product freeze times by 23
per cent," says Star's Rob
Lamb. "The plant also has a
very low ammonia charge,
which is isolated to the plant
room. Overall, the new
refrigeration plant has
enabled the client to expand
business without further
investment in building
infrastructure."
The Granville plant has a
total refrigeration capacity
of 1,227kW. The system was
designed with sufficient inbuilt
compressor capacity to
allow future expansion of
the existing cold store.
The new plant is located
in a purpose built plant
room adjacent to the main
building. It comprises two
low temperature CO2
compressors and surge
drum, supplying liquid CO2
to cold stores and blast
freezers. It also features two
ammonia compressors and
evaporative condensers, as
well as two ammonia to
CO2 cascade heat
exchangers. More articles from Star Refrigeration: |
