NORD Drivesystems NXD tupH surface treatment

The NXD tupH surface treatment has been developed by NORD to make aluminium as resistant as stainless steel, thus making it suitable for drive technology in hygiene-sensitive production areas such as food and beverage.

While stainless steel is the preferred material in wash-down areas, NORD said it can have disadvantages when applied to drive technology.

The new surface treatment is designed to strengthen the surfaces of drive components such as gear units, smooth motors and frequency inverters, making them resistant to harsh environmental conditions. In the NXD tupH version, it also provides protection against aggressive cleaning agents, chemicals, acids and alkalis. Drives made of aluminium are furthermore lighter and operate at lower temperatures.

Using the two-step treatment process, the treated surfaces are free from PFAS, and food-safe according to the FDA, the EU Regulation 1935/2004 and the respective regulations in Switzerland and the MERCOSUR states. They are therefore designed to be used in hygienically critical areas in the food, beverage, packaging, pharmaceutical or chemical industries.

For hygiene-sensitive environments, NORD has a selection of fanless smooth motors that can be cleaned easily, quickly and thoroughly. With the optional NXD tupH treatment, the drives are engineered to be wash-down capable, corrosion-resistant and sustainable.
