Yes. Amarillo Gear Drives are designed specifically for the demanding environment of cooling towers. Therefore, the drives may be physically larger than many of the “industrial” gear drives that have been adapted for use in cooling towers. Some tower modifications may be required to replace the existing gear drive with the Amarillo model. Some of the items that must be considered are shaft sizes, location of the fan in the fan stack, height of the input shaft from the base, required coupling length, and bolt hole pattern. Please provide the nameplate HP and speed of the motor being used as well as the desired reduction ratio (or fan speed) when requesting a recommendation for a replacement Amarillo gear drive. For tower modifications, Amarillo Gear recommends you engage a qualified cooling tower manufacturer to assist with these changes.
