GRUNDFOS HYDRO MULTI-E
The story behind the savings
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.
PLUG AND PUMP WITH HYDRO MULTI-E
Grundfos Hydro Multi-E pump systems are ideal for pressure boosting of clean water in places such as:
- Apartment Buildings
- Hotels
- Industry
- Hospitals
- Schools
System control interface
Advanced control interface installed in one pump. The control interface allows all control variables to be configured or viewed. With addition of flow measuring, system specific energy (kWh/gallon) can be displayed directly from control interface.
Single point power connection
The Hydro Multi-E offers a single point power connection disconnect panel and has individual pump disconnects for servicing pump while Multi-E system is in operation.
100% redundancy
All motors on system are capable of system control. Two sensors are installed as standard resulting in 100% system control redundancy.
