A frequency converter is an electronic device used to control the rotation speed and torque of an electric motor. The motor, in its turn, operates a load (such as a pump). A frequency inverter converts AC voltage of the mains in DC through a rectifier and a bench of capacitors of the middle circuit stabilizes it. The the inverter converts again the DC in AC with variable frequency.
Frequency converters for primary and wastewater treatment applications have a number if customised functions for the control of single and multiple pump systems. These functions specifically for pumps help to reduce running and maintenance costs throughout the pumping system's entire life cycle.
Frequency converters are able to achieve these results through:
Reduction in starting stress for the pumping system
Optimal speed for the instantaneous demand
Optimisation of energy consumption in parallel (booster) pump systems
Prevention of pump cavitation and dry running
Monitoring of energy consumption
Monitoring and protection of the pump motor
Energy saving expressed as kWh, in cash terms or in CO² emmissons
