Series M Geareducers (photo) are designed and manufactured to directly replace other gearboxes in field-erected cooling towers. The Geareducer’s primary function is to reduce the speed of the electric motor to optimize fan performance by maximizing air movement through the cooling tower and minimizing maintenance requirements. It provides primary support to the fan, anchors it against lateral movement, withstands shock loads at startup and during speed changes, and minimizes power-transmission losses and noise generation. The M Series features gears of case-hardened alloy steel. To further extend service life, the Geareducer is fitted with large oil passageways to help maintain lower oil temperatures. The Geareducer operates without the 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 surface area for cooler operation. — SPX Cooling Technologies, Inc., Overland Park, Kan.
