Introduction
How Much Improvement in
Operating Efficiency Does the
Altivar 212 Drive Offer?
The Altivar™ 212 adjustable speed drive operates more efficiently and
provides additional installed cost savings as compared to typical AC drives on
centrifugal pump and fan applications.
Applying AC drives on centrifugal pump and fan applications has been, and
continues to be, an excellent way to obtain energy savings and reduce
maintenance costs. By eliminating air flow dampers, inlet guide vanes, and
throttling valves—and by using an AC drive to control air and fluid flow—
users have reduced energy costs and maintenance costs.
Until now, AC drives from most manufacturers have provided similar rates of
energy savings by reducing the power the motor needs to provide optimum
flow. This bulletin describes the operating efficiency improvements and cost
savings that users can obtain by applying an Altivar 212 drive on centrifugal
pump and fan applications in place of typical AC drives, and the technology
designed into the Altivar 212 drive that provides these additional savings.
The Altivar 212 drive is able to provide a 3%–5% operating efficiency
improvement over typical AC drives on centrifugal pump and fan applications.
Based on typical duty cycle and energy costs, a 3%–5% improvement in
efficiency can save $120–$195 per year per drive when compared to typical
AC drives on a 15 hp motor. Figure 1 provides estimated energy costs of the
Altivar 212 drive, a typical AC drive, and operation with traditional contactor
control over a range of motor sizes.
