Electric Shredder TCO: 1250 E VFD vs Diesel — 195,000 EUR Energy Saving
Mathematical TCO model comparing the ARJES Impaktor 1250 E electric flagship (dual 250 kW asynchronous motors with VFD, 320 kW·h avg draw) against the TANA Shark 4400 diesel (Cummins QSM11 400 kW, 45 l/h avg burn) over 10,000 operating hours. At 0.15 EUR/kW·h industrial electricity and 1.50 EUR/litre diesel: 1250 E energy cost = 480,000 EUR; TANA fuel cost = 675,000 EUR. Delta = 195,000 EUR (≈30% saving). Compounded by zero DPF/SCR service, zero oil filters, zero injector maintenance, and zero AdBlue on the electric machine. VFD soft-start also eliminates inrush current spikes that would trip aging 20 kV CEE substation breakers — decisive for demolition sites fed from Soviet-era grids.

Technical Analysis
DRIVE ARCHITECTURE: VFD-CONTROLLED DUAL ASYNCHRONOUS VS CUMMINS DIESEL
The ARJES Impaktor 1250 E is the electric flagship of the Impaktor line, powered by two 250 kW asynchronous motors — one per shaft — each driven by an independent Variable Frequency Drive (VFD). The VFD ramps motor speed on a programmable torque curve, eliminating the inrush current spike that a direct-on-line start of a 500 kW motor would impose on the local grid. Under typical C&D load, the machine draws an average 320 kW·h per operating hour. The TANA Shark 4400 — the principal single-shaft diesel competitor in the 400 kW class — uses a Cummins QSM11 6.7-litre Stage V diesel burning 45 l/h average under equivalent load. The drive architecture is fundamentally different: electric VFD provides instantaneous torque modulation and per-shaft independent reverse; diesel-hydraulic provides fuel-burn autonomy but with mechanical drivetrain losses and DPF/SCR aftertreatment overhead.
10,000-HOUR ENERGY TCO MATHEMATICS
At EU industrial electricity tariff 0.15 EUR/kW·h (Q3 2026 average for industrial C&I consumers) and EU diesel price 1.50 EUR/litre (Q3 2026 average including excise): ARJES 1250 E energy cost = 320 kW·h × 10,000 h × 0.15 EUR/kW·h = 480,000 EUR. TANA Shark 4400 fuel cost = 45 l/h × 10,000 h × 1.50 EUR/l = 675,000 EUR. Energy cost delta = 195,000 EUR (≈29% saving for the electric machine). This is the pure energy line-item. The full TCO delta is larger: the 1250 E has zero DPF filter replacement (3,000 EUR per 4,500 h on the Cummins = 6,700 EUR/10k h), zero SCR catalyst service, zero engine oil and filter changes (250 EUR per 500 h = 5,000 EUR/10k h), zero AdBlue consumption (8% of diesel volume = 36,000 L = 18,000 EUR/10k h), and zero injector and valve-seat service. Conservative all-in delta: 225,000–250,000 EUR over 10,000 h.
The VFD soft-start capability of the 1250 E is decisive for CEE demolition sites fed from Soviet-era 20 kV industrial substations. A direct-on-line start of a 500 kW induction motor draws 6–8× rated current for 3–5 seconds — on a weak 20 kV grid with 1 MVA transformer, this sags the bus voltage by 15–20%, tripping undervoltage relays on every other load on the substation. The VFD ramps the motor from 0 to 1,500 rpm over 30–60 seconds on a programmable torque curve, holding inrush at 1.1× rated current — invisible to the substation. This enables deployment of the 1250 E on sites where a direct-on-line 500 kW start is technically impossible without a 200k EUR substation upgrade. The TANA Shark 4400 diesel has no grid dependency, but pays for it in 675,000 EUR of fuel over 10,000 hours.
STRATEGIC POSITIONING: WHEN TO CHOOSE ELECTRIC VS DIESEL
The 1250 E is the correct choice when (a) the site has stable industrial grid access (≥1 MVA transformer, <5% voltage drop under 500 kW load); (b) the operating horizon exceeds 4,000 hours per year (energy savings amortize the electric premium within 18 months); (c) the site is in a Zero Emission Zone (London, Paris, NYC post-2026) where diesel NRMM Stage V is prohibited; or (d) the site owner values the zero-exhaust, zero-NOx, zero-PM operating profile for permitting or ESG reporting. The TANA Shark 4400 diesel is the correct choice when (a) the site has no grid access (remote quarry, landfill cell expansion); (b) the operating horizon is under 2,000 h/year (energy savings cannot amortize the electric premium); or (c) the operator prioritizes RDF fraction precision (TANA adjustable counter-screen) over primary-shred survivability. For most CEE demolition contractors with grid-stable industrial sites, the 1250 E delivers 195,000 EUR energy savings + zero aftertreatment service + ZEZ compliance over a 10,000-h horizon.

Reference machine vs Competitor
ARJES Impaktor 1250 E vs TANA Shark 4400 — Electric Flagship vs Single-Shaft Shredder
TANA Shark 4400 — a single-shaft slow-speed shredder (32 t, Cummins 400 kW) with adjustable counter-screen for RDF-fuel fraction control, weighed against the ARJES Impaktor 1250 E electric flagship (500 kW VFD dual asynchronous motors) on 10,000-hour energy TCO and rebar wrapping failure modes. The same critique extends to the Komptech Terminator 6000 single-shaft architecture (28 t, CAT 440 kW).
Not recommended (counter-knife fracture, planetary gear shear risk)
Verdict
Advantage
480k EUR electric vs 675k EUR diesel — 30% energy cost delta over 10,000 h
The ARJES Impaktor 1250 E ships with dual 250 kW asynchronous electric motors driven by VFDs.
Under load the machine draws an average 320 kW·h per operating hour — over 10,000 hours at 0.15 EUR/kW·h industrial tariff that is 480,000 EUR.
The TANA Shark 4400 with a 400 kW Cummins diesel burns ~45 l/h, costing 675,000 EUR at 1.50 EUR/litre over the same horizon.
The 195,000 EUR energy delta is compounded by zero DPF/SCR service, zero oil filters, zero injector maintenance, and zero AdBlue consumption on the electric machine.
Advantage
Single-shaft spool effect vs asynchronous self-cleaning
The TANA Shark 4400 and Komptech Terminator 6000 use a single-shaft rotor with stationary counter-knives.
On C&D waste with rebar mesh, wire, and sheet steel, the rotor acts as a spool — wire wraps around the shaft body, extrudes the Hardox side seals, and invades the bearing journals.
The ARJES Impaktor 1250 E uses two asynchronous shafts rotating at different speeds and directions: the differential shears the wire, the counter-rotation strips it off the shaft body, and the machine self-cleans without operator intervention.
Advantage
Hydraulic damping vs planetary gear shear on rail / I-beam drop
When a TANA or Komptech single-shaft rotor ingests a rail section, tank track, or I-beam, the tramp metal jams between the rotor and the stationary counter-knife.
The entire kinetic load transmits through the planetary gear train into the flywheel and engine — bursting hydraulic motors or shearing planetary teeth.
The ARJES Impaktor 1250 E uses independent hydraulic drive per shaft with high-resolution pressure sensors: the SCU detects the pressure spike in milliseconds, halts the blocked shaft, and reverses it while the second shaft continues to push the obstruction out.
