Air cooled condensers are used in power stations to condense waste steam after the steam turbine. The heat is dissipated to the ambient air by convection. This is a closed cooling circuit.
The steam circulates through a heat exchanger which is cooled by the air flowing round it. The accumulated condensate is collected and re-used in the power plant process. Flender gear units for air condensers are specially designed for condensing turbines in power plants.
The fan is directly mounted on the two-stage helical gear unit which absorbs the reactive forces of the rotor via a reinforced output bearing arrangement. Flender gear units for oil and gas and air condensers are optimized for both fixed and variable speeds and are characterized by high operational reliability.
