EM DTm Vertical close-coupled multistage pumps with Drive-tech MINI

EM DTm Vertical close-coupled multistage pumps with Drive-tech MINI

The vertical close-coupled multistage pumps EM with the new inverter device Drive-Tech MINI is an state-of-the-art booster set which combines efficiency, simplicity, innovation and safety:

  • Efficiency: The Drive-Tech MINI achieves overall energy savings up to 40 %, compared to conventional speed control systems.
  • Simplicity: The Drive-Tech MINI is mounted directly onto the motor control box. It is already supplied with a 2.0 meter power cable and a 1.50 meter cable to connect with the pressure transducer.
  • Innovation: The Drive-Tech MINI can be controlled manually by the board panel or via Bluetooth by the Franklin Smartphone App “FE Connect Drivetech” (Android and IOS), enabling you to set and monitor the system remotely, save working data and increase the pump performance.
  • Safety: The integrated Class B (EN55011) input-filter prevents any type of disturbances in the domestic network to ensure a reliable use. The filter follows EMC Directives (electromagnetic compatibility).
