Manufacturing plants repair, replace and install new equipment and systems all the time. Almost universally, the reason would be the need to improve some aspect of the operation. The articles in this month’s issue of Process Cooling look at various equipment meet this goal. The authors discuss these bottom-line goals via energy savings, increased efficiency, greater reliability and lower maintenance needs, which all together mean lower costs.
Poor water quality can push a
plant’s cooling system over the edge, causing a surge in maintenance costs.
According to Glenn Dobbs in “The ROR of Cooling Tower Filtration,” the
installation costs of a well-designed filtration system often are small compared
to what an operator would pay to fix problems stemming from poor water quality.
Dobbs, who is executive vice president at Valve & Filter Corp., Arvada,
Colo., says that incorporating an efficient filtration system into a cooling
tower can extend equipment life and lower upkeep costs, both of which provide a
significant return on resources.
In “Preventing Cooling System
Downtime,” Randy Simmons, vice president of Air Solution Co., West Chester,
Ohio, notes that an ideal approach to keeping maintenance costs in check is to
have a plan and stick to it. He suggests that operators identify the “mission
critical” systems across their facility and then implement aggressive
procedures and technologies to streamline the maintenance process. The result,
he says, will be reduced costs.
Dr. Karin Jahn, managing
director at eurammon in Frankfurt, Germany, points out in “Sending Chills Down
the Line” that keeping perishable products such as cheese, meet and fruit fresh
requires impeccable refrigeration throughout the entire supply chain, which
requires energy. To keep a lid on energy costs, many companies rely on natural
refrigerants such as ammonia or hydrocarbons, which consume up to 30 percent
less energy. Additionally, natural refrigerants do not deplete the ozone layer
or contribute to global warming, Jahn says.
Money also can be saved by
using a closed-loop cooling tower system in plastics manufacturing, says
Sheetal Desai, operations and marketing director, Cooling Technology Inc.,
Charlotte, N.C. “Closing the Loop on Water Quality” discusses how water
contamination can damage equipment, cause equipment failure and harm workers’
health. However, recycling process cooling water with a closed-loop cooling
tower or water chiller (central or portable) can help keep water quality high,
reduce energy use and decrease maintenance.
Also, in “How to Choose the
Right Water Cooling System,” Don Robson, vice president of engineering at
Robson Industries Inc., West Chester, Pa., describes the factors involved in
designing or specifying a process water cooling system to help you successfully
match a cooling strategy to your process.
In this issue, case histories detail
how some processors have pursued the improvement and savings aspect of
equipment use. “Pure Efficiency” explains how facility costs are kept in line
at one of Denmark’s biggest refrigerated and cold storage companies. Claus
Sorensen A/S, switched to a high-purity compressor oil from Petro-Canada
Lubricants that allowed the company to reduce operating expenses while
optimizing compressor efficiency.
Case history “Chemical-Free
Water Treatment” answers this question: What do an international agricultural
business, a chemical technology center, a peaker power plant and a razor-blade
manufacturer all have in common? Each of these companies has selected the same
water treatment technology to reduce water and energy use and improve the bottom
