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

Available today, Dextreme Swap replaces the main hydraulic pump with a Digital Displacement® pump, custom software, and digital controller. Delivering a 15% reduction in fuel use and carbon dioxide emissions, compared to an excavator fitted with a conventional swash plate pump.

    Danfoss Power Solutions awarded £4.9 million grant to accelerate decarbonization of excavators
    Thursday, September 14, 2023

    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%.

    Dextreme systems improve excavator energy efficiency by 15% to 50%, regardless of the power source, while maximizing productivity. The Dextreme pathway consists of three incremental system solutions: Swap, Flex, and Max. The simplest configuration of the system, Dextreme Swap, is now available.

FAQ

With Dextreme systems, the excavator hydraulics is powered with a Digital Displacement® pump, which reduces losses in different system components. 

  • The Swap system improves the efficiency of the main pump as well as the engine use. 
  • The Flex system minimizes even more the excavator losses, specifically in the main control valve thanks to a flexible pump allocation. 

Dextreme systems can minimize fuel consumption and CO2 emissions and/or maximize productivity of excavators. Either way, our customers and their end customers achieve more with less. This allows the industry to recover a Dextreme system in a short payback period. 

No matter the energy source (diesel, electric, hydrogen), Dextreme systems improve the TCO of excavators. 

With the simple Dextreme Swap system, you benefit from 15% fuel savings by only replacing the pump and adding a digital pump controller. This system is also suitable for retrofit opportunities. Also, OEMs are partnering with Danfoss to apply even more advanced system architectures such as Dextreme Flex. 

Excavators account for 50% of all CO2 emissions generated by construction machinery. And within excavators, around 90% of CO2 emissions come from machines of ten tons or more. Focusing on energy efficiency is the fastest and cheapest way to achieve decarbonization. Dextreme systems optimize efficiency of medium and large excavator without compromising productivity.
