Purge Air Consumption
Dryer is designed to operate either in 8 minute (-40°F/-40°C)
or 4 minute (-94°F/-70°C) cycle.
6.6.1 Maximum Purge Flow
Maximum purge flow is the amount of purge flowing through
the off-stream tube when the purge/repressurization valve
is open. After the purge/repressurization valve closes the
purge flow will gradually decrease as the off-stream tube
repressurizes to line pressure.
6.6.2 Average Purge Flow
The average purge flow is the actual amount of flow aver-
aged over the entire purge/repressurization cycle. It in-
cludes the maximum purge flow for a set amount of the
purge/repressurization time and the volume of air used for
repressurization.
6.6.3 Minimum Outlet Flow
Determine minimum outlet flow available from dryer by
subtracting maximum purge flow from inlet flow to dryer
(specification by authorized dealer).
IMPORTANT: Air compressor should be adequately sized to
handle air system demands as well as purge loss. Failure to do
so could result in overloading air compressors and/or insuf-
ficient air supply downstream.
6.6.4 Timer Board Setting & Remote Control
With the dryer de-energized (disconnect plug), verify position
of the cycle time DIP switches. The DIP switches are located
on the timer board in the cabinet.
