Upgrading & safety optimization of two HEINKEL HF1000 Inverting Filter Centrifuges
As part of a plant modernization, the electrical controls, the local operator panel and all electrical components inside the centrifuges were exchanged at two HEINKEL HF1000 inverting centrifuges. The new control cabinets including the inverter of the rotational drive with a power feedback unit and the safety PLC. This modernization increases the reliability of the machine and in addition a cost saving through an efficient use of electric energy. In contrary to the inverter with braking resistor, the energy during braking of the centrifuge will not converted in heat, the REVCON power feedback unit can feedback the energy into the main power supply.
This approach has two advantages:
1.) Use of the feedback power
2.) Energy savings because it is not necessary to dissipate the heat of the braking resistor with expensive air conditioning.
