ADDAX

The ADDAX transmits torque through composite disc packs between the drive and the fan shaft. As with a disc coupling, the elastic deflection of these packs compensates the axial, radial and angular misalignment that occurs in the often long drivetrains of cooling tower fans. The composite construction keeps the coupling light and thereby reduces the moving masses in the drive.

The key advantage of the composite material is its corrosion resistance. Cooling towers create a permanently humid, chemically aggressive atmosphere in which metallic components can corrode. The ADDAX is designed precisely for this environment and runs there with low maintenance, since it needs no lubrication and is insensitive to the moist, corrosive surroundings. Its low weight also simplifies the installation and handling of the long fan shafts.

As a specialised cooling tower coupling, the ADDAX can be maintained through its composite disc packs as wear and spare parts.
