<strong>The</strong> turbo generator unit comprises the<br />
following modules:<br />
<strong>Steam</strong> turbine<br />
Gearbox/generator unit<br />
LP lubricating oil system<br />
HP control oil system<br />
Control cabinet<br />
<strong>The</strong> lubricating oil module, control oil<br />
module and the control cabinet can be<br />
individually arranged around the unit.<br />

Benefits of the modular concept:<br />
Proven turbine design with robust<br />
technology and high availability<br />
Space-saving, low-noise epicyclic<br />
gear generator unit (up to 25 MW)<br />
High level of efficiency thanks to<br />
optimised turbine design and use of<br />
epicyclic gearing<br />
Use of proven system modules for<br />
lubricating oil and control oil<br />
Compact control cabinet as blackbox<br />
for connection via bus system<br />
to the central control system<br />
Low investment costs<br />

Five different turbine sizes cover a performance<br />
range from 1.5 MW to 50 MW.<br />
<strong>The</strong> <strong>MARC</strong> production programme<br />
includes backpressure, heating and<br />
condensing turbines that can also be<br />
fitted with extraction and bleed ports.<br />
