FLENDER transmission units for wet cooling towers

Wet cooling in wet cooling towers is specifically regulated by the cooling tower’s transmission unit. Besides the motor helical bevel geared units are generally utilized. FLENDER transmission units are specially conceptualized for use in wet and hybrid cooling towers. The fan speed, which is the fundamental design criterion, is optimized by means of diverse gear ratios. If necessary special gear ratios can be designed. The ventilators resulting reaction forces are directly absorbed by the transmission unit.

As the motor is installed outside the cooling tower, the transmission unit which is placed in the middle of the tower is driven from the outside by a long composite coupling which is likewise available in the FLENDER product portfolio.
