The Grundfos Hydro Multi-E pressure booster system is an innovative boosting solution for variable water flow applications such as pressure boosting, process, and hydronic water circulation 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 state-of-the-art integrated ECM MLE motor, the Hydro Multi-E arrives ready to install.
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.
Grundfos integrated variable frequency drive and motor combined eliminates complexity by matching variable speed motor, drive and control logic components.
