Dynamatic’s Gary Patterson gave a 45-minute presentation during the MWEA Wastewater Administrators Conference, a two-day event held in Michigan in January 2017.

Patterson discussed the topic of one of his recently published articles on tying carbon emission reduction to saved energy at “negative costs”. The discussion concentrated on the concern over climate change and driving energy users in finding ways to reduce or eliminate emissions of greenhouse gases, most notably CO₂. Although there isn’t one single solution to this complex problem, the presentation emphasized an easily implemented improvement to save energy in the wastewater treatment industry with “optimal speed” or “high efficiency” pumping by using variable speed.

When compared to VFDs, especially in medium voltage wastewater applications, variable speed pump-drive systems can save up to 65% in capital costs alone. Further, the operating efficiency of a variable speed drive increases relative to the normal operating speed of a motor, making them ideally suited for wastewater applications. Dynamatic’s drives and controls are rugged and reliable, simple to maintain and have been proven to outlast VFDs by as much as 6:1.

The benefits of variable speed pumping have long been recognized, including lower energy cost, lower ownership cost, and lower capital cost. In today’s economy and with greater environmental awareness, a significant reduction of a company’s carbon footprint can now be added to the list of benefits.

Electromagnetic variable speed drives can often prove to be the best path to achieve these results, and can be shown to pay for themselves over a long period of service. Dynamatic is invested in continuing their work on lowering energy costs to help protect the environment. Gary Patterson will be making this presentation all over the country throughout the year to help people understand how emissions can be reduced by energy savings achieved through the installation of variable speed pump-drive systems.

Dynamatic will be at these upcoming events in 2017:

• METALFORM Mexico in Monterrey, Mexico on May 2-4; Booth 3509
• EASA Convention in Tampa, Florida, on June 25-27; Booth 345
• WEFTEC in Chicago, Illinois on October 2-4; Booth 1050
• FABTECH in Chicago, Illinois on November 6-9; Booth A5052
