(August 8, 2016) The minimum efficiency standards for general-purpose, three-phase motors have been raised.
“The U.S. Department of Energy (DoE) recently released new efficiency standards for commercial and industrial pumps that are based on efficiency levels negotiated by manufacturers, efficiency advocates, and other stakeholders,” reported MachineDesign.com, “In addition to establishing the first-ever national efficiency standards for pumps, the final rule also provides a mechanism for energy-efficiency programs to incentivize high-efficiency pump packages.”
According to the site, “The new standards apply to clean water pumps between 1 and 200 hp, which are used for a wide variety of applications such as irrigation, circulation of hot and cold water in commercial buildings for heating and cooling, and pressure boosting in high-rise apartment buildings. The standards will require the least-efficient 25% of today’s pumps market to be redesigned to improve efficiency and reduce energy losses.”
