SPPA-E3000 Drive Modernization
is how to optimize the energy efficiency of drive
systems with frequency converters and energysaving motors.
2. Energy-efficiency analysis
Suitable drive systems are identified and the
energy-cost-savings potential is precisely quantified. Based on the actual on-site conditions,
we draw up a concrete optimization concept.
The Task
More than 97 % of the entire life-cycle costs
of drive systems are attributable to the costs
of the energy needed to operate them. Over
two thirds of the plant's auxiliary power
demand comes from electrical drive systems.
About 30 % of the drives for say pumps and fans
could be run more efficiently. This considerable
savings potential is waiting to be tapped.
3. Technical implementation
■ Planning and engineering
■ Replacement of obsolete
and inefficient hardware
■ Installation of high-quality frequency
converters and high-efficiency energy-saving
motors
■ Commissioning and parameterization
of the components
■ Optimization of operating times
and operating points
■ Final measurements, calculation
of power consumption
■ Best-in-class project management (VGB
Quality Award)
Our Solution
comprises assessing the potential savings,
analyzing suitable measures and implementing
them to modernize the drive systems. The focus
is first set on those drives that promise a shortterm payback for the cost of the upgrade.
We focus primarily on
■ electronic speed control instead
of mechanical throttling
■ modernization of installed
frequency converters
■ use of energy-saving motors
■ recovery of decelerating energy
during breaking
The solution can be linked up to the existing
instrumentation and control system for operator
control and monitoring.
Electronically controlled drive systems save significant amounts
of energy.

Optimization is carried out in 3 stages:
1. Assessment of potential
We estimate the theoretical savings potential.
If this stochastic estimate reveals theoretical
potential for optimization, we make you
a concrete proposal for a site analysis of
your entire drive systems.
