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 – from environmentally-friendly paint to long-life high-performance coatings.

This also includes Nord’s nsd tupH surface treatment, which provides corrosion protection for gear units, smooth surface motors, frequency inverters, and motor starters in wash-down optimised cast aluminium housings.

“In almost all industries, it is important to efficiently protect plant and machinery, as well as the drive technology used from external influences like dirt, moisture, spray water and aggressive media,” the company said.

“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.”

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 per cent, high-solid paints contain a large proportion of solid material and combine the emissions benefits of hydro paints with the functionality of solvent-based coating materials,” Nord said.

“In addition, the lower solvent proportion of only 20 per cent allows for very short drying times in production – a decisive advantage over water-based coating systems.”

For the electrical sector, Nord offers robust and long-life powder coatings. The treated surfaces are resistant to impact, scratches, and wear. It is 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, according to Nord, is that powder coatings are free from solvents and make an important contribution to protecting the environment.

An alternative to stainless steel

In case of stringent requirements on surface and corrosion protection, Nord claims that the nsd tupH surface treatment is the technology of choice. This is not a coating, but a surface treatment that creates a protective layer, which is permanently bonded to the substrate material.

Thanks to the special method, the surface is made corrosion-resistant and harder, and makes aluminium behave like stainless steel, with regard to corrosion protection.

“So, nothing can detach or flake off. Damage remains locally restricted and does not spread,” Nord explains.

“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.”

Nord’s nsd tupH surface treatment is available for most of its aluminium drive system and are not only suitable for hygienically sensitive applications in the food sector, but also for various applications in process and pharmaceutical industries.

It is typically used on conveyor belts, pumps, mixers, or agitators, but also in water and sewage plants and car wash facilities.

Nord Drivesystems is a member of the Australian Packaging & Processing Machinery Association (APPMA).
