3 Vorecon Classical and Modular 30+ Years, 600+ Units Worldwide kw / HP United States kw / HP China 1400kW / 1877HP Australia 8000 kw / HP Oman 3

4 Efficiency Why Did Voith Develop the VoreconNX? Ideal Solution VoreconNX Vorecon Modular Vorecon Classic RKM Costs 4

5 Based on Proven Vorecon Technology Torque Converter Planetary Gear Parallel Shaft Gear

6 Basic VoreconNX Design with Power Splitting Principle Input Shaft Output Shaft Torque Converter Planetary Gear Parallel Shaft Gear

7 Vorecon NX Product Requirements Maximum Efficiency... Comparable to Vorecon Classic/Modular Part Load Efficiency... Considerably increased compared to Vorecon Classic/Modular Lead Time... Shorten lead times (< 6 months) due to a high grade of standardization and modularization Product Costs... Reduced product costs due to part quantity effects within the new series Target Market... Pipeline compressor drives up to approximately 10MW

8 Counter Rotational Torque Converter Actuation Ring Rotor Impeller Impeller Turbine Angular Ball Blades Bearings Hollow Shaft (connected to sun gear superimposition) Stator Hydraulic Oil Supply Unit Vorecon Input Shaft (connected to main motor + planet carrier)

9 Counter Rotational Torque Converter: Advantages Efficiency... High speed ratio range with almost maximum efficiency Actuation... Simple and robust hydraulic actuation principle with system integrated PI controller Counter rotational torque converter... At nominal operating point the turbine rotates counter rotational to the impeller wheel, therefore the fixed planetary gear can be eliminated

19 Output Torque [% Nominal Output Torque] Efficiency Difference Vorecon NX vs. Vorecon Classic % +3% 0% -1.5% NP NWR S3 Refrigeration (P out =5265kW / n out =5994rpm) NP C.O. P-74 S3 Injection (P out =8939kW / n out =11408rpm) NP ROG Antwerpen SAT S2 (P out =3956kW / n out =11029rpm) What s my benefit? Output Speed [% Nominal Output Speed]

20 Our Idea... 3 Casings 4 Sets of Planetary Gears 8 Torque Converter Sizes + Tailor Made Parallel Shaft Gear Standardization Customization

21 ...Your Benefit Smaller footprint compared to Vorecon Classic Available with an integrated oil system Better serviceability due to horizontally split casing Reliable and Proven Vorecon Technology Improved Efficiency at Part Load by 8% compared to Vorecon Classic 6 months delivery time Highly Competitive Price (25-35% less than Vorecon Classic)
