To meet the demands posed by special environmental conditions and high hygiene requirements, Nord Drive Systems developed the nsd tupH (Sealed Surface Conversion System) anti-corrosion treatment: an innovative surface treatment making aluminium drives extremely robust and durable.

The nsd tupH surface treatment is an outstanding anticorrosion treatment for gear units, smooth motors, frequency inverters and motor starters in washdown-optimised cast aluminium housings. Applying a special method, the surface is made corrosion-resistant and harder; in this way, aluminium behaves like stainless steel with regard to corrosion protection.

This is not a coating, but the surface treatment creates a protective layer which is permanently bonded to the substrate material. In contrast to painting or coating, nothing can detach or flake off. Damages remain locally restricted and do not propagate. The surface is easy to clean and largely resistant to acids and alkalis. It is even possible to use high pressure cleaners or a great variety of aggressive media.

The nsd tupH surface treatment is available for almost all NORD aluminium products. For nsd tupH aluminium drive units, all DIN and standard components, including drive shafts, are made from stainless steel.
