Cooling towers present unique challenges for a transmission: housings must be sealed against the environment and protected from corrosion, bearings must be fortified to support a fan's rotation, and vibration and noise must be kept to a minimum. Hansen industrial gearboxes exceed these challenges with:

• Weather-resistant epoxy coating with option.
• Grease purged labyrinth seals at the low speed shaft prevent water or moisture, while Oil –Lock™ and Oil Guard™ systems offer maintenance free sealing on high speed shaft extensions.
• Extended bearing span to increase dynamic stability.
• Careful placement of fill and drain plugs to ensure ease of maintenance.
• Wide range of bearing and shaft arrangements to meet any application requirements.
