The Motor Driven Unit policy guidelines

This two-part project examined the options for harmonising technical standards and regulations for Motor Driven Units (MDUs), focusing on pumps, fans and compressors.

All motor systems are responsible for 53% of global electricity consumption; while the global annual energy consumption of pumps, fans and compressors is estimated at 6,560 TWh, which is larger than the total electricity consumption of China.

The first report, published in 2016, describes existing standards and regulations for MDUs in Australia, Brazil, Canada, China, European Union, India, Japan, Korea, Mexico, New Zealand, Russia, Saudi Arabia, South Africa and USA.

It found that the variation in terminology and definitions related to MDUs across regions makes it difficult to compare standards and regulations applied in different countries and can lead to confusion. Furthermore, differences in regulated performance requirements across regions impairs the international trade of products.

During 2017, work was completed on the second report into opportunities to improve global alignment in both technical standards and policies for MDUs.
