Midwest Towers, Chickasha, Okla., now carries the Composite Drive Shaft line from Amarillo Gear Co., Amarillo, Texas, for cooling tower service. Amarillo designs and manufactures gear drives for mechanical-draft cooling towers and air-cooled condensers.

Each drive shaft connects the electric motor to the gearbox input shaft, thereby transmitting torque to rotate the cooling tower fan. The drive shafts accommodate spans ranging from 2 to 20', from small HVAC systems to large field erected towers.
