The new MLE motors exceed IE5 motor efficiency standards, set by the International Electrotechnical Commission, currently the highest efficiency level worldwide for electrical motors. Premium efficient motors are equal to IE3 level, so these motors represent two levels above NEMA Premium Efficiency. Highest motor efficiency and combined motor and VFD efficiency level in the industry. Increased combined VFD and motor efficiency results in an additional 7% to 10% decrease in energy consumption over NEMA Premium Efficiency motors and conventional variable frequency drives. This and the new motor result in potential 40% energy savings over the competition, and makes the Hydro MPC BoosterpaQ the most efficient pumping system in the industry.
