The Hydro Multi-E pressure booster system is an innovative boosting solution for commercial building pressure boosting, HVAC and irrigation applications.
For energy savings and comfort, the Hydro Multi-E system uses parallel mounted Grundfos CRE variable-speed pumps that have a reputation for providing the ultimate in efficiency and reliability. With a state-of-the-art integrated ECM MLE motor, the Hydro Multi-E arrives ready to install.
Many pumps system applications have a variable flow rate requirement and spend the majority of operation time in a much lower part load condition compared to design condition. Multiple pump systems offer increased hydraulic efficiency at part load.
The Grundfos ECM MLE motors exceed IE5 motor efficiency standards, set by the International Electrotechnical Commission, currently the highest efficiency level worldwide for electrical motors. NEMA premium efficient motors are equal to IE3 level, so these motors represent two levels above NEMA premium. The result of this increased efficiency is reduced energy consumption/operating costs by 7-9%, based on a typical domestic water load profile.
