9.4 ENERGY MANAGEMENT SYSTEM (OPTIONAL)
The Energy Management System option includes a dew point sensor
that transmits the outlet pressure dew point to the Microprocessor
Controller. The Microprocessor Controller displays the outlet pressure
dew point in real-time. This option package also includes Energy
Management System, an energy savings feature that matches moisture
loading and regeneration energy usage. Drying equipment is typically
operated below full flow rating and/or below maximum water loading
capacity of the desiccant bed. The Energy Management System feature
utilizes the data communicated from the dew point sensor and extends
the normal timed switching sequence in proportion to the moisture
loading on the dryer.
When the Energy Management System feature is turned off, all
switching sequences occur as described in Section 7.3. When the
Energy Management System feature is activated, the drying sequence
is governed by the outlet pressure dew point as measured by the dew
point sensor. When the sampled outlet dew point registers below the
customer set point (-43°F default for -40°F dryers; -102°F on -100°F
dryers), an immediate change in dryer operation will not be noticeable.
The dryer will continue its normal regeneration process through tower
re-pressurization. Once the tower is re-pressurized, both towers will be
at line pressure but air will only flow through the tower indicated by the
status panel. Tower switch over sequence is delayed until the dew point
elevates above the Energy Management System setpoint, at which point
tower switch over will occur.

NOTICE
New desiccant has a moisture holding capacity higher than the dryer's
design regeneration capacity. The desiccant ages in a three- to six-
month time period at which point it stabilizes to an "aged" state. During
this aging process at initial start-up or after desiccant replacement, the
Energy Management System feature should be deactivated.
