NORD nsd tupH aluminium drives

NORD Drivesystems nsd tupH aluminium drives offer permanent corrosion resistance through a sealed surface conversion system.

The drives are given a smooth, ultrahard surface which, in contrast to paint, is unaffected by blows or scratches. The drives have been tested in wet applications and are resilient against blistering and corrosion as per ASTM and ISO standards. The unit showed no loss of adhesion or chipping during the spray test and produced no corrosion even after 2000 h.

In demanding atmospheres, the drives can be used beyond the usual service life of paint-coated systems. Their resilience and prolonged service life reduces service and maintenance requirements. 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.

nsd tupH is available for all aluminium-enclosed drives — four gearbox families, smooth-surface motors and distributed drive electronics units. Treated systems resist cleaning agents in the 2–12 pH range.
