Dextreme systems
Designed for excavators, Dextreme systems decarbonize the industry by delivering 30% energy savings today.
Designed for Excavators
At the core of each Dextreme system is the Danfoss Digital Displacement pump, the first and only truly digitally controlled hydraulic pump for off-highway machinery. The pump's dedicated digital controller activates each piston individually, providing fast and accurate response to system demand, enabling superior machine controllability. The pump provides unmatched full and part load efficiency by using only the pistons needed to meet the load.
The incremental aspect of Dextreme systems minimizes risk for excavator OEMs now while positioning them as long-term leaders with a cost-effective system pathway to significant decarbonization.

Product range
Dextreme SWAP
Dextreme SWAP offers software configurable excavator working modes – switchable at a fingertip. The fast response of the Digital Displacement® pump allows for optimal torque control of the engine.
More useful work can be done in Productivity mode. Or more fuel can be saved in Fuel saving mode by running the engine at lower speeds and without compromising on productivity.
Dextreme FLEX
With a Dextreme FLEX system, the Digital Displacement® pump (DDP) meets the hydraulic system demands of the excavator in the most efficient possible way. The flexible allocation of the DDP outlets results in minimized main control valve (MCV) losses.
In Fuel saving mode, Dextreme FLEX unlocks an unprecedented 30% lower fuel consumption in excavators – without compromising on productivity.
Reduce battery requirement by 24.8%
New research published by Danfoss Power Solutions shows that combining an electric motor with a Digital Displacement® pump in an excavator is the most efficient way to turn battery energy into hydraulic work.

The grant is from the U.K. Government’s Department for Energy Security & Net Zero through the Red Diesel Replacement Phase 2 Competition, which provides funding for projects developing low-carbon alternatives to red diesel for the construction, mining, and quarrying sectors. Danfoss will use the funds to validate its Dextreme Max system in a 30-ton electric excavator, which it expects will reduce energy consumption by 50%.
