Steam Turbines

A broad range of industrial steam turbines

MAN Diesel & Turbo is one of the leading suppliers of industrial steam turbines worldwide with a comprehensive range of products and services.

Our multi-stage reaction-type steam turbines (DK/DG) can be used for both power generation and mechanical drive applications and are available in sizes up to 160 MW. MARC® steam turbines are multi-stage, highly standardized reaction type turbines and cover sizes up to 40 MW. Our single/multi-stage impulse steam turbines (MARIM) can be used for power generation applications and are available in sizes up to 10 MW.

The possible applications include:        

Power Generation                                        Mechanical Drive

 Waste-to-Energy (WtE)  Refinery
 Pulp & Paper  Iron & Steel
 Combinded Cycle (CC)  Fertilizer
