ECONO-PURGE CONTROLLER (OPTIONAL)
NOTE: At ini al startup and during the first six months of con nuous dryer opera on, the Econo -Purge Controller
logic SHOULD NOT BE ACTIVATED. A condi oning process must occur in new desiccant, this will allow
the desiccant to remove its precise water vapor capacity from the airflow.
The func on of EPC is to conserve energy by elimina ng unnecessary dryer cycling, purge air consump on, and com-
pressor power consump on.
The EPC works by u lizing a moisture sensi ve probe to measure the water vapor content of the outlet air flow. The
moisture content of the sample air stream indicates the wetness of the drying tower's desiccant bed. The purpose of
the probe and its associated electronics is to first measure the "wetness" of the air within the desiccant beds and
then regenerate the desiccant beds only when the moisture loading reaches a pre-set maximum, desired dew point.
The ECONO- PURGE CONTROL Plus is packaged with a digital dew point controller and High Humidity Alarm op on.
The digital dew point controller allows the end user to pre-set a desired dew point at which the dryer will start the
Energy Savings Mode. This controller also allows the end-user to pre-set a dew point at which a high humidity alarm
condi on would occur. See High Humidity Alarm op on for full descrip on. See the digital dew point controller Own-
ers Manual enclosed for changing desired dew points.
NOTE: Energy Savings Mode is factory preset
to ac vate at -30° F dew point. High Hu-
midity alarm is factory preset to +10° F dew
point.
