ARJES Impaktor 350 EVO II vs Doppstadt DW 3060 — torque, throughput on roots and biomass, and shaft-change economics.
| Spec | ARJES Impaktor 350 EVO II | Doppstadt DW 3060 |
|---|---|---|
| Drive concept | Dual-shaft asynchronous low-speed hydrostatic | Dual-shaft low-speed mechanical |
| Engine | Volvo Penta TAD 583 VE (Stage V) | John Deere 6068 (Stage V) |
| Drive power (kW) | 177 | 160 |
| Drive power (HP) | 238 | 215 |
| Operating weight (kg) | 21 000 | 20 500 |
| Cutting torque (Nm) | 130 000 | 105 000 |
| Shaft speed (rpm) | 11–35 (variable) | 14–24 (variable) |
| Hydrostatic service interval (hrs) | 500 | 300 |
| Shaft cassette swap time (hrs) | 2 (quick-change) | 48 (in-frame shaft change) |
| Setup time (hrs) | 0.5 (SCU auto-calibration) | 1.0 (manual shaft alignment) |
| Material | ARJES Impaktor 350 EVO II | Doppstadt DW 3060 |
|---|---|---|
| Old wood / biomass | 11 – 25 t/h | 9 – 22 t/h |
| Green cuttings / root wood | 20 – 45 t/h | 18 – 38 t/h |
| Commercial waste | 10 – 22 t/h | 8 – 18 t/h |
| Reinforced concrete (with rebar) | On-demand shred | Not recommended |
Gate fees, landfill taxes, and electricity prices swing the verdict by ±30%. Run the live TCO model for your region to see real payback.
The ARJES Impaktor 350 EVO II. Its 130 000 Nm of cutting torque is 24% higher than the Doppstadt DW 3060’s 105 000 Nm, which translates directly into fewer stall events and higher throughput on dense root wood feedstock.
ARJES quick-change cassette system completes a shaft swap in ~2 hours. The Doppstadt DW 3060 requires an in-frame shaft change of approximately 48 hours — a 24× difference that compounds across a year of mixed-feed operation.
No. Doppstadt does not recommend rebar concrete for the DW 3060 due to mechanical driveline vulnerability. The ARJES Impaktor 350 EVO II handles reinforced concrete with rebar on demand.
