Develon (Doosan) Tracked excavators, DX, DH

AdBlue (DEF) capacity & service interval

Develon (Doosan) tracked excavators, DX, DH use AdBlue (DEF) with a capacity range of 31,5 to 70 liters. Service intervals include a check every 10 hours. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The DX225LC-7 (Stage V, S/N 1001 onward) carries a 31.5-liter AdBlue tank, the smallest capacity among the listed models, which reflects the smaller engine displacement relative to the larger LC-class excavators in the range.
  • A 10-hour check interval is specified for the DX225LC-7 Stage V under normal use conditions, meaning AdBlue level verification is tied to a very short service cycle compared to most fluid checks on heavy equipment.
  • The DX300LC-5 with the Doosan DL08P engine, covering 2016-2022, holds 60 liters of AdBlue, while the DX300LC-7 with the Doosan DL08V engine, from 2019 onward, holds 62 liters — a 2-liter increase between the fifth and seventh generation of the same base model class.
  • The DX340LC-5 with the Doosan DL08P engine, spanning 2016-2021, shares the 60-liter AdBlue capacity with the DX300LC-5, despite being a larger machine class, indicating the same SCR tank design was used across both models in the -5 generation with the DL08P engine.
  • The DX380LC-5 with the Scania DC09 engine, covering 2016-2021, holds 70 liters of AdBlue — the largest capacity in the listed specifications — while the DX380LC-7 with the same Scania DC09 engine, from 2019 onward, holds 63 liters, a reduction of 7 liters between generations despite retaining the same engine family.
  • All six configurations are noted as using a selective catalytic reduction system, which is the emissions control technology that consumes AdBlue by injecting it into the exhaust stream to convert nitrogen oxides into nitrogen and water vapor.
