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

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
