MOTOX Cooling Tower Geared Motors

Geared Motors for Use in the Rugged Environment of Cooling Towers

MOTOX cooling tower geared motors have been designed for the use in the rugged environment where industrial water is cooled – and also for climate control systems (HVAC). The gear units can absorb high axial and radial forces. Further, MOTOX cooling tower geared motors distinguish themselves as a result of the high operational reliability – guaranteeing reliable and maintenance-free operation.

Geared motors are available as single-speed or pole-changing versions with pole numbers 8/4 and 6/4. The high IP65 degree of protection and special protection against humid& moist environments is provided as standard.

MOTOX cooling tower geared motors are implemented as helical geared motors. They are available in the power range up to 200 kW and rated gear unit torques up to 20,000 Nm.
