Oil
& Gas
For
powering electric submersible pumps, even
at cable lengths beyond 25 km (15.5miles),
there is only one reliable choice - the
Perfect Harmony drive. Unlike conventional
drives that require site-specific, dedicated
filters to control voltage transients
and harmonics, the Perfect Harmony eliminates
the need to retune for well relocation.
The Perfect Harmony is the only drive
that allows you to change cable lengths
and pump sizes within the drive's power
range without redesigning an output filter.
When transporting energy assets, many
of the world's largest pipeline operators
are replacing traditional mechanical prime
movers with the Perfect Harmony to drive
their electric motors for pumps and compressors.
The Perfect Harmony allows for the sequential
operation of large AC motors, thus reducing
system costs while maintaining unparalleled
power quality, system availability and
minimized energy usage.
Water
In more than 20 countries, the Perfect
Harmony helps our industrial and municipal
customers by operating their water and
wastewater treatment plants more efficiently,
improving system control and reducing
operating power costs. Efficient operation
reduces the need for chemicals and significantly
decreases after-delivery and clean-up
expenses. The Perfect Harmony also has
proven experience in hazardous disposal.
Power
Generation
The Perfect Harmony drive helps improve
the efficiency of thermal, cogeneration
and nuclear power generation facilities,
enabling electric utilities to lower costs
of economic dispatch and to release more
capacity to customers. As a result of
market deregulation, electric utilities
are adapting their operations to increase
asset utilization and reduce maintenance
costs while better serving power-quality
sensitive customers. Many types of industrial
equipment in customers' facilities can
no longer tolerate voltage disturbances.
To enhance quality and comply with industry
standards, the Perfect Harmony virtually
eliminates harmonics so that large, complex
and expensive harmonic filters aren't
necessary.
Mining
& Metals
Various mining applications, including
compressors, conveyors, electric submersible
pumps, slurry pumps and drag lines, rely
on the Perfect Harmony drive. For many
of these challenging applications, the
Perfect Harmony drive offers optional
regeneration capability (ability to drive
and break the motor in both forward and
reverse directions, while returning excess
energy to the supply or other equipment).
The Perfect harmony drive also complements
NELCO's electrical automation systems
expertise, a mainstay of global steel
production.
Chemical
& Plastics
Replacing steam turbines or fixed-speed
drives with the Perfect Harmony drive
produces many benefits for the chemical
and plastics industry, including more
accurate process control, energy savings,
greater availability and lower maintenance
costs.
Cement
The Perfect Harmony drive's ability to
optimize the production process and improve
quality and productivity, while reducing
labor and energy costs; make it the ideal
solution for the cement industry. Additionally,
the Perfect Harmony ensures improved process
control and reduces mechanical wear, which
allows cement producers to keep their
machinery running for longer periods of
time.
Marine
The Perfect Harmony helps our marine customers
reduce costs and enhance power quality
and reliability, while maximizing space.
Additionally, the Perfect Harmony offers
regeneration capability that many marine
customers demand. Through NELCO's alliances
with ship owners, designers and leading
component suppliers, we can produce comprehensive
electrical systems for all types of marine
applications.
Paper
Through an advanced control strategy called
sensor-less or closed-loop vector control,
the Perfect Harmony drive provides precise
torque and speed control to a wide range
of demanding applications in the pulp
and paper industry.
