Cooling

At the end of stripping, the regenerating tower is
repressurized. The cooling cycle valve opens (V13) and
cooling begins. During cooling, a portion of the dry outlet air is
directed into the regenerating tower to reduce the temperature
of the bed prior to tower shift. Cooling and stripping combine to
provide extremely low dew points and to eliminate dew point
fluctuations during tower shift.
As this design has been carefully tailored to your specific
application, the dryer operation can be easily understood by
combined reference to the process flow schematic; the
electrical ladder schematic; listing of various options available
and included; and descriptive operational legends.
