13.4 Chain and Sprockets
13.5 Desiccant Rotor
The state-of-the-art desiccant rotor supplied with NWBDC 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.
