SPX Cooling Technologies Highlights Video Series on Marley® Geareducer® Gear Drive


Overland Park, Kan. – SPX Cooling Technologies, Inc., a full-line, full-service industry leader in the design and manufacture of evaporative and air-cooled heat exchangers, has issued a series of three short and informative videos on the Marley Geareducer, a gear drive that is standard equipment in many Marley factory-assembled cooling towers, and optimizes cooling performance and minimizes maintenance.

The first video, presented by Mitch Case, sales engineer, starts off the series with a brief overview of a key advantage of the Marley Geareducer gear drive for controlling cooling tower mechanical equipment: reduced loss of efficiency between the motor and the drive system itself. Case also highlights the extended warranty, noting that the first oil change is needed only after five years of operation.

The second video, presented by product manager Jerome Jennings, highlights the significant energy and installation savings of the Marley Geareducer gear drive compared to belt drives. The Marley Geareducer gear drive produces 98 percent energy transmission consistently, higher than a belt drive that can drop to 90 percent efficiency or less as belts stretch and wear over time. Installation costs are also lower, because Marley Geareducer gear drives do not require external vent lines.

After installing the Marley Geareducer gear drive, routine maintenance and oil changes are not required for approximately five years. By comparison, a belt drive system requires quarterly belt inspection and adjustment and fan shaft bearing lubrication, as well as annual replacement of the belt.

The final video, also hosted by Jennings, provides some practical tips on how to change the oil in the Marley Geareducer gear drive. Smart maintenance practices covered include routinely checking oil lines for leaks or blockage, recording static and operating oil levels, and properly draining older oil from the gear drive.

Jennings also recommends testing oil quality semi-annually, and offers additional oil quality considerations. In new Marley towers, operators only need to change the synthetic oil supplied with the drive after five years of operation. In older towers with turbine mineral oil, it should be replaced every six months.

These videos provide a useful reference library of Marley Geareducer gear drive information, helping customers gain a working knowledge of this component’s function and importance. To watch additional videos, visit: http://spxcooling.com/video.
