I have located the problem. The Hankison air dryer did fail due to
a problem in the control board and probable misadjustment of the
purge pressure under the recent humidity levels around here.
It was my mistake to overlook the moisture indicator on the unit itself
(at the time of the posting of my email) and look merely at the other
two moisture indicators installed by the compressor people (not dryer
people) on the inlet and outlet of the dryer,
So they've ordered new parts and we'll just be on nitrogen till
Monday or so.
Thank you all for the great help you've been.
Sincerely,
John Chung
