Help Customers Save Energy & Money with Power Drive Systems

New study shows major savings potential with power drive systems on commercial pumps

Presented by Sarah Widder and Nate Baker

As COVID-19 and its physical and economic impacts reshape new and existing industrial and commercial systems, operators are looking at how to most efficiently run existing commercial and industrial spaces that may be used very differently in the future.

While adding variable speed capability in commercial buildings is not a new idea, a new analysis confirms major energy and cost savings is available by pairing those products with a power drive system (PDS) – regardless of a pump’s load variability. A PDS combines an electric motor, adjustable speed controls and sensors that provide feedback to the equipment, allowing the equipment to slow down or speed up to meet current demand. This idea and the added flexibility a PDS can provide may be even more important as we move forward in uncertain times.
