| Spec | ARJES Impaktor 850 | Terex Ecotec TDS V20 |
|---|---|---|
| Drive concept | Twin-shaft asynchronous low-speed hydro-mechanical | Twin-shaft medium-speed hydrostatic sizing chamber |
| Engine | Volvo Penta TAD 581 VE (Stage V) | Scania DC13 (Stage V) |
| Drive power (kW) | 260 | 367 |
| Drive power (HP) | 350 | 493 |
| Operating weight (kg) | 24,000 (borderline hook-lift) | 37,000 (heavy-haul permit mandatory) |
| Fuel consumption (l/h, avg) | 25 – 35 | <15 (exceptional) |
| Shaft / rotor type | Quick-change cassette (shafts + bearings + gears) | Twin-shaft sizing chamber (welded tooth configuration) |
| Shaft maintenance downtime | 2 hours (cassette swap) | 24 – 48+ hours (field hardfacing + screen replacement) |
| EU 40t GVW transport compliance | Borderline (lowboy, minimal permits) | Heavy-haul mandatory (37t exceeds 40t GVW with truck) |
| Hydraulic thermal limit (°C ambient) | +42 (CLEANFIX reversible cooling) | Standard (hydrostatic cooling adequate at 492 HP) |
| Setup time (hrs) | 0.5 (SCU auto-calibration) | 2.0+ (lowboy unload + conveyor deploy) |
| Material | ARJES Impaktor 850 | Terex Ecotec TDS V20 |
|---|---|---|
| C&D waste / reinforced concrete | 66-88 ST/h | 44-66 ST/h |
| Waste wood / biomass | 22-39 ST/h | 28-44 ST/h |
| Commercial / industrial waste | 39-61 ST/h | 33-55 ST/h |
| Reinforced concrete (rebar ≥ 16 mm) | On-demand shred (asynchronous anti-wrap) | Medium-speed sizing (rebar wrapping risk) |
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 TDS V20's Scania DC13 engine operates at a highly optimized point on its thermodynamic efficiency curve, decoupled from the final shaft speed via its hydrostatic drive loop. This allows the prime mover to maintain steady-state RPM regardless of load transients, avoiding the severe fuel consumption penalties of mechanical belt-driven machines that must run at full throttle to maintain rotor speed under varying loads.
Despite the TDS V20's exceptional fuel economy (<15 l/h), the ARJES Impaktor 850 delivers lower overall TCO for multi-site C&D deployments: 2-hour cassette swaps eliminate 24-48h hardfacing downtime, hooklift-compatible transport eliminates heavy-haul permit costs, and low-speed asynchronous drive tolerates contaminated feed that would stall the TDS V20's medium-speed sizing chamber. For single-site clean-wood operations, the TDS V20's fuel savings may prevail.
The TDS V20's medium-speed sizing chamber is optimized for pre-sorted, relatively clean feedstocks where precise particle sizing is the primary objective. When encountering heavy rebar or tightly wrapped wire in reinforced concrete, the medium-speed shafts are more susceptible to wrapping and stalling than low-speed designs. The ARJES Impaktor 850's low-speed asynchronous drive with independent reversal is specifically engineered for contaminated C&D where tramp metal encounters are routine.
