4" 3~ 4000N Heat Pump Submersible Motors
4" 3~ 4000N Heat Pump Submersible Motors
The Heat Pump Motor
Many modern heating systems extract heat that is stored in aquifer / river water. Such so-called two-pit or open systems require low-power, high efficiency 3-phase submersible motors.
To meet the demands of this Application Franklin Electric developed a special 4", 160 up to 1100W / 400V-50Hz encapsulated submersible motor optimized for shallow settings and low power consumption.
With growing success of this motor, calls for extended range of operation and higher available power levels have been recorded. As a result, we are pleased to introduce the new range of multiple-power, efficiency-improved 4" motors for heat pump applications.
