Benefit for Attendee
Attendee of this course will learn about the successful applications of variable speed pumping with variable speed drives as a way to lower life cycle costs.
Course Introduction
Pumping systems account for nearly 20% of the world’s energy used by electric motors and 25% to 50% of the total electrical energy usage in certain industrial facilities. Significant opportunities exist to reduce pumping system energy consumption through smart design, retrofitting, and operating practices.
Course Content
