When Trelleborg Sealing Solutions
became concerned about the energy
use of its hydraulic power packs, it
turned to ABB Drives Alliance
member, Inverter Drives Systems
(IDS) for a solution.

IDS installed four 18.5kW ABB
standard drives to automatically
maintain the system pressure just
below the system unload value, using
a pressure transducer to feed back to
the drive’s internal PID control.

Energy savings achieved on this
application are £2,742 per motor, or
£10,960 for the four motors, with a
payback time of 11 months.
