Voith Receives First Order for Retrofit of AeroMaXX Technology in the Air Separation Industry

• The existing Voith parallel shaft gear unit will be upgraded with Voith AeroMaXX technology

• It will help to significantly increase efficiency by decreasing power loss and oil consumption

• Conducted simulations have shown significant energy savings for the customer, a global player headquartered in Europe

The inner housing and optimized sleeve bearings of the AeroMaXX technology significantly reduce power loss and oil consumption

Voith will retrofit a parallel shaft gear unit with the Voith AeroMaXX technology at an air separation plant in China. The respective turbo gear unit from Voith is currently in service as part of a steam turbine compressor driveline in northern China. The contract includes retrofitting the existing housing and bearings to reduce the power loss of the gearbox by up to 30 percent as well as subsequent re-commissioning of the gearbox.

With the installation of AeroMaXX, the producer of technical gases will be able to significantly increase energy savings of its plant that delivers oxygen to a nearby methanol plant. According to upfront calculations, the AeroMaXX technology will lead to a reduction of approximately 190kW per hour, which equals annual steam cost savings of an estimated EUR100,000 (USD110,400) and a coherent amortization time of around 1.5 years. Start of commissioning is expected for May 2020.

Reduction of power loss and oil consumption

AeroMaXX technology minimizes losses by separating lubrication and cooling, with no additional accessories needed due to its passive mechanical construction. Such losses usually appear at high pitch line velocities of up to 200m/s when the oil swirls and squeezes into the gear mesh. The solution has a passive-mechanical character and requires no additional accessories. Operators profit from identical design standards, unchanged overall operating behavior and maximum reliability.
