11.3 Chain and Sprockets
11.4 Desiccant Rotor
The state-of-the-art desiccant rotor supplied with NWDC series dryers will last very long
under ideal conditions. Due to the nature of desiccant and honeycomb matrix they make very
good filters. The life of desiccant is directly related to the air born contaminates passed
through it. Avoid exposure to acidic gases or unusual amounts of dust. Although the
desiccant rotor is considered a cleanable/washable media, the preferred method of cleaning
is to blow dust out with low pressure compressed air and to reactivate the rotor at a
maximum temperature of 380°F (190°C) for 15 minutes. Washing the rotor, although
possible, is not recommended as wash water impurities may contaminate the desiccant.
Proper filtration and preventing contact with chemicals will greatly improve the life of the
desiccant. Inspect the face of the rotor to see that no surface damage has occurred. The
rotor should turn smoothly upon the shaft.
