Permanent-magnet motor : in replacement of cooling towers’ transmissions
The transmission system of motor fans (belts and gearboxes) requires a strengthened care for the good cooling of a process, in particular if they are placed in the wet airflow. The elimination of these critical organs decreases the costs and the maintenance operations while securing the reliability of the equipment.
Replacement of reducers or belts by a permanent-magnet motor reduces significantly maintenance costs and operations of handling. Besides, this new generation of motors coupled with their frequency converters guarantees efficiency much superior to those of the asynchronous ones (minimum 6 %).
A solution saving the installation, and reduces maintenance costs: guaranteed 5 years.
