Daimler Trucks North America
commissioned KLG Jones to
provide investigation, design
and commissioning services to
improve the operation and the
energy efficiency of the central
utility plants in three of the
Freightliner truck manufacturing
facilities.
The Cleveland Manufacturing
Facility central plant contains 6
centrifugal chillers with a combined
capacity of 10,000 tons,
and the facility was having significant cooling problems. KLG
Jones installed data loggers
on all of the primary/secondary/
tertiary pumping loops and
determined that only half of
the chiller capacity was being
delivered to the air handling
equipment in the three major
buildings on site. KLG Jones
redesigned the entire central
plant, removed the secondary
pumping loop, converted the
tertiary loop into a secondary
loop, put frequency drives on
all secondary pumps, changed
three-way valves to two-way
valves on all air handling units,
and added a small chiller to
serve the office area. On completion
of the work all of the
chiller and air handling systems
will be fully commissioned. The
work will result in significant
energy savings and improved
operation of the central plant.
KLG Jones is providing similar
services for the Mt. Holly
plant.
