Motor and Reducer (Fan Group)

The motor and reducer operate as a group with the fan and fan stack on the tower deck. They are among the most critical components of a water cooling tower. Units with fan diameter Ø ≤ 1600 mm may use only an electric motor; larger units use motor and reducer together. Fan peripheral speed is 52–60 m/s. Motors and reducers are used in V1 vertical flange configuration. Motors are Class F insulated and IP56 protected against dust, oil and moisture.
