Right-angle double reduction gearboxes for large cooling tower fans: self-lubricated, anti-reverse, replacements for Amarillo, Sumitomo Paramax and Hansen P4.
Large cooling tower fans turn slowly with high torque. Double reduction right-angle gearboxes provide the higher ratio and torque they need, and are the standard drive in field-erected towers of power plants and refineries.
Self-lubricating design without an external oil pump, anti-reverse device and generous bearing sizing give long life in the wet, vibrating tower environment.
We supply original-make gearboxes and equivalents that match shaft heights, mounting and ratio, so the drive shaft, motor and fan remain unchanged. For smaller fans see the single reduction gearbox.
We supply replacement parts for crossflow and counterflow towers of all major manufacturers. Send us the tower make, cell size and photos, and we confirm the matching part.
Yes, when shaft heights, mounting, ratio and torque match. We compare the drawings before we quote.
The tower make and model or cell size, photos of the nameplate and the existing part, dimensions and quantities. For new towers and upgrades: water flow, hot and cold water temperatures, wet-bulb temperature, water quality and site location.
