Danfoss’ Dextreme Max system reduces electric excavator power consumption by 35%, extending runtime by 53%

Undertaken with a £4.29 million grant from the UK Government, Danfoss demonstrated that its Dextreme digital hydraulic architecture reduced excavator power consumption by 35% across a representative duty cycle mix, corresponding to 53% longer runtime on a single charge. 

The results confirm the potential of the Dextreme Max system to significantly increase energy efficiency and accelerate the electrification of large excavators.

Danfoss’ Dextreme Max system recovers energy that would otherwise be wasted. The system’s integral component is the DDP1X0D, a hydraulic pump/motor with multiple independently controlled outlets. The Dextreme Max system provides independent actuator supply, eliminates flow-sharing losses, and enables energy recovery from excavator motions such as boom lowering.
