Tower Fan

Tower fan can be turned on direct drive belt drive or use the drive shaft and gearbox. The direct drive applications, fan or blower blades are mounted directly to the engine shaft. No pulleys, belts and timing drives used in this design. The engine power is transmitted directly to the fan, without any drive losses. Belt-driven fans use several belt pulleys and flexible belts, power transmission from the shaft of the engine to the shaft of the fan. Losses incurred in die disk configuration, when straps start gliding on the pulleys, converting some of the power of the engine to heat and noise. This configuration is typically found in a forced draught.

The drive shaft and gearbox is used in the dungeons, where the motor and fan shafts are perpendicular to each odier. In these applications, the engine is installed with its shaft in a horizontal plane, while the shaft die axial fan is oriented to die in the vertical plane. Drive gear is used to change the die direction of the shaft of engine power output of 90 at reducing the frequency of rotation of the fan die. The deceleration of the die fan gear transmission of vibrations of large blades, lowers the atmosphere speed below the level of drift eliminators are required and reduces the noise level of the tower. This configuration is typically found in a forced draught.

Electric motor of the fan of the cooling tower can be widiin saturated medium tower chassis or attached to a shelf, on the outer side of the case. Since the motors in enclosure is designed for the expected environment, choice of place, as a rule, on the basis of service considerations and personal preferences. The tower engines have special wires and insulation requirements to die debt encountered in these applications. They are designed to withstand the harsh conditions of the tower environment. Therefore, defective tower engine cannot be replaced by any totally enclosed motor with the same power rating.
