Specifications

The HERTZ ONE control panel is an automatic control and protection
system for one (HERTZ ONE) or two (HERTZ TWIN) electric
centrifugal pumps equipped with three phase induction motors.
The control panel power supply can be three phase or single phase.
The HERTZ ONE and HERTZ TWIN control panels include a pump control
software and allow regulation of motor speed via an electronic
frequency changer (INVERTER) that powers the pump motor. On varying
the rotation speed, the pump performance varies in terms of flow rate
and head, allowing optimal use in every condition and saving energy.


Materials

Technical details:

• Energy saving: the controller modulates the pump according to the
hydraulic energy request of the plant with respect to a direct
connection in the network
• Quicker and improved regulation
• Hammering reduced thanks to gradual start-up and stop
• Improved comfort in the heating, air conditioning and pressure
boosting systems
• Reduced peak current
• Exchange at every powered pump re-start (HERTZ TWIN)
• Speed modulation on both pumps for excellent regulation (HERTZ
TWIN)
