About the Marley 3000 Series
Marley Geareducer units are the standard gear drive for Marley cooling towers — found in power plants, refineries, and large commercial HVAC systems across the US. SPX Cooling Technologies provides direct factory parts support.
The 3000 is a cooling tower drive, heavy duty unit with a rated capacity of 10–40 HP and output torque of 3,500–14,000 ft-lb. Typical operating weight is 195–358 lbs. Mounting configurations include Flange-mount.
Marley Geareducer units most commonly fail from bevel gear wear, bearing fatigue, and seal failure from water exposure in cooling tower environments.
When your Marley 3000 Series fails, downtime costs mount fast. Our standard rebuild turnaround is 8–14 business days with free freight both directions. Emergency 24–72 hour service is available. We publish pricing before teardown — no surprises.
