- Danfoss' new digital hydraulic system cuts battery energy use by 35% and boosts runtime over 50% on electric construction equipment.
- DDP180D pump motor replaces the conventional swashplate pump and features ten individually controllable outlets to deliver hydraulic force only where needed.
- Develon DX300LC‑7 crawler excavator equipped with three 140‑kWh batteries was used to test the new pump, confirming the efficiency gains.
- Red Diesel Replacement Phase 2 Competition provided a grant that helped fund the project, aiming to develop lower‑emission alternatives to red diesel.
- Alasdair Robertson said Danfoss will keep optimizing the system, marketed as Dextreme Max, to further increase energy savings.
Why it matters: Construction firms can run electric excavators 50% longer on the same battery, cutting fuel‑related costs and emissions, while Danfoss secures a competitive edge in the emerging low‑carbon heavy‑equipment market.
