Electric drives and controls


Complete control and automation technology, along with co-ordinated power electronics – with our individual total concepts we offer solutions that provide for the future.

Example: Cargo Pump Drive

The requirements:

Control concept for loading and unloading a bitumen and chemical tanker in an area at risk from explosion. Depending on the medium to be conveyed, the housing and storage temperatures of the cargo pump, together with the suction and delivery pressure of the pump, must be variable. As bitumen has to be kept permanently at a minimum temperature and circulated, a high level of availability is required.

The solution:

Visualization via touch panel with bus link to PLC. Inputting of sensor technology in the field via intrinsically safe circuits is followed by processing in the PLC. Monitoring and control of hydraulics, cooling and lubrication systems. Complete switching system designed for 300 KW in each case. In order to guarantee the required availability the complete system has been designed so as to be redundant.
