Corrosion Protection

Optimal Protection for Demanding Environments

nsd tupH™ is our solution for corrosive environmental conditions. Used in a variety of our aluminum gearboxes, motors, & frequency converters in many different industries e.g. food, chemical, pharmaceutical, & marine.

Exceeding Protection Standards

Cleaning processes with highly effective washing additives are constantly being expanded and are making increasingly higher demands on hygienic design and corrosion resistance.

The standards for the food industry, chemical industry, and the pharmaceutical industry call for intensive, strict washing, and disinfection processes.

In order to prevent material destruction by cleaning agents and disinfectants, the design and coating of machines for these applications must be smooth and ensure the best possible cleanability in manual or automated cleaning cycles.

Geared motors and frequency converters with a smooth surface and the nsd tupH™ surface finish meet the requirements for wear resistance and cleanability.

NORD DRIVESYSTEMS has introduced new solutions (in terms of materials, treatment and processing) for the surfaces of motors, gears, and components while offering a protection package with exceptional resistance to cleaning agents typically used in food, chemical, and pharmaceutical industries.

Sealed Surface Conversion System

nsd tupH™ from NORD DRIVESYSTEMS is the perfect solution for high-performance applications and extreme conditions. It is an alternative to multi-layer painting and stainless steel in highly corrosive environments.

  • Complies with FDA Title 21 DCFR 175.300
  • Easy to clean surfaces
  • Resistant to acids and alkalis (wide pH range)
  • No spreading of corrosion, even if damaged
  • No Flaking
  • Corrosion Resistant - prevents contact corrosion
  • Free from chromates

How It Works

While with conventional methods the paint is only applied superficially and possibly even covers porous areas, the nsd tupH™ process has a base layer that permanently penetrates the surface of the aluminum and ensures a strong foundation for the connection of the surface coating. This combination offers extreme durability and is a harder surface than an untreated aluminum alloy.

Modern gearboxes must be robust, compact, powerful, economical, and light. The advantage of aluminum is its low weight, because weight is a cost factor, especially when the gear itself is a load that must be moved as part of an automated positioning system. For this reason, aluminum alloy has become the preferred material for gearboxes in many areas.

NORD DRIVESYSTEMS improves many of the optimal properties that an aluminum alloy offers for NORD gear housings. The material also has a certain inherent corrosion resistance and does not need additional protection in all cases. At the very least, an aluminum case is a much better conductor of heat than one made of cast iron. The resulting low operating temperatures have a beneficial effect on the internal transmission components and allow a longer service life.
