Sealed Surface Conversion System

NORD DRIVESYSTEMS manufactures permanently corrosion-resistant drives by means of the nsd tupH sealed surface conversion system. Aluminum drives are treated to produce a smooth ultra-hard surface that in contrast to paint, is unaffected by blows or scratches. The drives are tested and proven in applications with a maritime atmosphere. Previous to that, they have proven their resilience against blistering per ASTM D714, corrosion per ASTM D610-08, and scribe per ASTM D1654-08 according to DIN EN ISO 2409. Additionally, ASTM D3170 Gravelometer test showed absolutely no loss of adhesion or chipping. The ASTM B117-09 salt spray test according to DIN EN ISO 9227 produced no corrosion even after 2,000 hours.

In demanding atmospheres, nsd tupH drives can be used much beyond the usual service life of paint-coated systems. Their resilience and prolonged service life significantly reduces the service and maintenance requirements placed on customers. In addition, the treatment ensures high process safety: since no coating is applied but the surface itself is hardened, there can be no pollution of products or process media as for instance with chipping paint. Even heavy impacts or scratches do not diminish the corrosion resistance. In contrast, scratches in paint or coatings can result in the damage spreading to adjoining areas, effectively rendering the protection useless. nsd tupH is approved for food applications according to FDA Title 21 CFR 175.300. Thus treated systems resist cleaning agents in the pH2 to pH12 range. nsd tupH is available for all aluminum-enclosed drives - four gearbox families, smooth-surface motors, and distributed drive electronics units.
