The gearbox of your cooling tower is a supremely valuable asset, and we realize how important it is for you to keep it running at its best. SPX Cooling Tech has in-house engineers that have been designing Marley Geareducers for over 70 years. Who can troubleshoot and diagnose your particular situation better than the one who designed it? Whether you have questions on Geareducer® operation and maintenance, need components to perform a repair yourself, or want to send your unit back to us for the highest level of care, SPX has the solution.


In-house Marley Inspection and Repair: Send your Marley Geareducer to our repair facility in Houston or Olathe, Kansas, where we will diagnose the gearbox’s condition to determine a level of repair that is most appropriate for your particular model.
