To protect its drive systems from corrosion, chemicals, wear, scratches, impacts, and moisture, NORD DRIVESYSTEMS offers a wide range of different methods for each application area – from environmentally friendly painting to long-life high-performance coatings and the innovative nsd tupH surface treatment.
In almost all industries, it is important to efficiently protect plants and machinery as well as the drive technology used from external influences like dirt, moisture, spray water, and aggressive media. NORD motors and drives are already designed with a high level of protection. Furthermore, high-performance coatings, paints, and finishing processes protect the surfaces of drive systems and ensure an aesthetic and uniform appearance.
High-solid paints protect the environment
For paint finishes, NORD uses the latest generation of high-solid paints which considerably reduces the emission of solvents far below the legally required limits. With up to 80%, high-solid paints contain a large proportion of solid material and combine the emission benefits of hydro paints with the functionality of solvent-based coating materials. In addition, the lower solvent proportion of only 20% allows for very short drying times in production – a decisive advantage over water-based coating systems.
Powder coatings for the electrical industry
For the electrical industry, NORD offers robust and long-life powder coatings. The treated surfaces are resistant to impact, scratches, and wear. They are resistant to weather and chemicals and are even more robust than conventional NORD paints. The anti-static properties of the electrically conducting powder paints prevent static charging of the drive technology and so downtimes are reduced to a minimum. A further advantage: Powder coatings are free from solvents and make an important contribution to protecting the environment.
nsd tupH surface treatment: An alternative to stainless steel
In case of stringent requirements on surface and corrosion protection, nsd tupH surface treatment is the technology of choice. Thanks to a special method, the surface is made corrosion-resistant and harder and makes aluminum behave like stainless steel with regard to corrosion protection. This is not a coating, but a surface treatment that creates a protective layer that is permanently bonded to the substrate material. So nothing can detach or flake off. Damage remains locally restricted and does not spread. The drives are easy to clean and largely resistant to acids and alkalis. It is even possible to use high-pressure cleaners or apply aggressive media. An nsd tupH treatment is available for most of the NORD modular drive systems made from aluminum. They are not only suitable for hygienically sensitive applications in the food sector but also for various applications in the process and pharmaceutical industries. They are typically used on conveyor belts, pumps, mixers, or agitators, but also in water and sewage plants and car wash facilities.
Competent advice from the NORD experts
Selecting the optimal surface protection – painting, powder coating or nsd tupH – for the respective application primarily depends on the environmental and operating conditions at the installation site of the drive solution. The NORD experts advice on the selection.
