Corrosion-resistant surface treatment for aluminium drive units

NORD DRIVESYSTEMS will be exhibiting its aluminium drive units for the food and beverage industry at ANUGA FOODTEC, from 20th to 23rd March. The lightweight, corrosion-resistant gear units, smooth surface motors, frequency inverters and motor starters in wash-down optimised die cast aluminium housings are extremely robust and durable thanks to a special surface treatment: NORD nsd tupH surface protection.

For use in demanding environments, NORD offers the extremely effective nsd tupH anti-corrosion treatment for aluminium drive units. With this process, the material is hardened below the surface. The surface treatment creates a protective layer which is permanently bonded to the substrate material. It is based on an electrolytic process and gives aluminium corrosion resistance properties which are similar to those of stainless steel. The scratch-resistant surface is more than seven times harder than untreated aluminium alloy. The drives can easily withstand high pressure steam washing or contact with aggressive media.

Aluminium drives in oyster farming
Among other applications, NORD nsd tupH modules are used in the many conveyor systems which are used in oyster farming. While cast iron geared motors only remain operational for one or two years due to corrosion by the salty environment, the aluminium drive units from Northern Germany offer a durable and economical solution, which usually completely outlives the ten year life cycle of the conveyor belts which they drive. Therefore, users save time and expense for the maintenance and repair of their systems.

An economical alternative with many variants
nsd tupH drive units are a robust, durable and economical alternative to painted cast iron geared motors or stainless steel versions. The nsd tupH treatment is available for all NORD aluminium products, unlike stainless steel drives, which are only offered in a small number of versions by other manufacturers. For nsd tupH aluminium drive units, all DIN and standard components, including drive shafts, are made from stainless steel. The fanless smooth motors do not spread germs and also run very quietly. They are available as synchronous and asynchronous motors and fulfil efficiency classes IE2 and IE3 (asynchronous motors) and IE4 (synchronous motors).

In addition to robust and corrosion-resistant geared motors for the food and beverage industry, NORD DRIVESYSTEMS will of course also present other products from its comprehensive range of drives and drive electronics at ANUGA FOODTEC 2018 in Cologne. NORD can be found in Hall 10.1, on stand B061.
