Gearboxes for field-erected cooling towers
SPX Cooling Technologies' Series M Geareducer gearboxes reduce the speed of the electric motor to optimize fan performance.
Series M Geareducer gearboxes provide primary support to the fan, anchors it against lateral movement, withstands shock loads at start-up and during speed changes, and minimizes power transmission losses and noise generation. The M series features gears of high strength, case-hardened alloy steel machined to AGMA Quality Class 9 and above. It is designed to fit into cooling towers for easy replacement and has heavy duty double row interstage bearings for 100,000 hours of life or more. To further extend service life, it is fitted with large oil passageways to help maintain lower oil temperatures. The new Geareducer operates without need for oil pumps, oil filters or oil coolers. It runs with two-stage gear reduction for efficient power transmission and the external cooling fins maximize the surface area for cooler operation.
