Cooling Tower Mechanical PartsSingle Reduction Cooling Tower Gearbox (Right Angle)
Right-angle single reduction gearboxes for cooling tower fans: spiral bevel gears, anti-reverse device, replacements for Amarillo, Hansen and other makes.

Adjustable-pitch FRP cooling tower fans with low-noise blades and leading-edge protection. Replacement fan assemblies for TUF-LITE II/III and other makes.
The fan is the main energy consumer of a cooling tower. Modern FRP fans with aerodynamic blades move more air for less power than old aluminium fans, and their pitch can be adjusted to match the airflow to the motor and the season.
FRP blades are light and corrosion-resistant, which reduces loads on the gearbox. Leading-edge protection extends blade life, and low-noise blade shapes help where noise limits apply.
Fans are supplied as complete assemblies with hub and hardware, balanced and ready to install in the existing fan stack. For very large diameters see the large-diameter axial fans.
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.
Usually yes. Replacing older fans with efficient FRP fans typically reduces fan power noticeably at the same airflow.
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.
